Description

UNIVERSAL MULTIPLE COMPOSITE FILTER HOLDER FOR MICROSCOPE LIGHT CONDENSERS

The following invention relates to a universal multi-compound filter holder for microscopes, thanks to which notable improvements are achieved in relation to conventional filter holders known so far, whose improvements affect the simplification of the interaction with the parts to achieve the lighting effects , to the way of placing the filter and multiple filter holder in the microscope filter holder, to the amount of filters that it is capable of housing and its movement, and, thanks to this, it gives rise to the application of a type of contrast lighting Color controlled.

BACKGROUND OF THE INVENTION

The filter holders of the standard capacitors (both dark field, phase, light field, and oblique) are known for a single filter, which, in addition, is permanently still being impossible to rotate, with which it limits the ability to use various optical contrast techniques for which several filters and patches of different types that can also rotate are needed. For this type of optical contrasts some microscope companies have designed different types of exclusive accessories for each type of lighting, for example, olympus in the CX2 series owns the CX41 (see Fig. 12), with all the necessary accessories for these common systems , such as phase contrast accessory, dark field stop,

polarization system, clear field condenser ... etc. being always exclusive and incompatible with other brands and of a high cost. However, all of them lack the ability to, even

combining the accessories between them, always in very exclusive models, to be able to offer high contrast illuminations by controlled projection of wavelengths, with different directions, on the sample, in polarized light, in addition to being able to simplify all these systems in a more practical way and universal and, consequently, this universal multiple composite filter holder has been devised, for filter holders, with which a novel and practical lighting system can be applied, the characteristics of which are the subject of this

. .,

lnvenClon.

DESCRIPTION OF THE INVENTION

The universal multiple compound filter holder for microscopes is a filter holder of the type fitted with the filters fitted, with an eccentric thyme with respect to the passage of light that makes the axis of rotation to open and close it, and a rotation stop to fit the passage of light with that of the condenser. From this embodiment, the universal multiple composite filter holder

It is essentially characterized by the fact that it is divided into two parts, upper and lower. The upper part is placed in the microscope condenser filter holder and the lower part can house three filters in three filter holders that fold and unfold and allow the filters to rotate

3600 during observation, and is attached to the top by magnets through pins by guides.

In an optional embodiment, the multiple composite filter holder

universal presents, once integrated into the microscope, an increase in the optical capacity of the same in the sense of converting a simple filter holder, into three filter holders, placed in its lower part, with filters that rotate 360 ° with a slight movement of the finger, and a patch of light placed on its upper part. The upper and lower parts of the universal multiple filter holder are attached by magnets at the level of the microscope condenser filter holder. The universal multiple composite filter holder has sufficient versatility that allows it to interact with it during the observation in the sense of inserting and removing the filter holders, put and remove different types of filters and rotate them, and obtain high contrast color illuminations by controlled projection of wavelengths on the sample in a polarized light field, thanks to the ability of the transparent injected polystyrene resin, both injected as extruded, to change the direction of the light by rotating the filters of this compound in a polarized light field, since it is for this reason for which it is designed, in addition to combining this lighting, which is applied with this filter holder, with other lighting systems such as dark field, phase contrast, DIC nomar sky and oblique, thanks to the design it has that allows it with all the options that entails

DESCRIPTION OF A PREFERRED EMBODIMENT

The microscope filter holder consists of a piece (figure 11) as an open disk-shaped box (101), with a hole in the middle to allow the passage of light (102), to fit the filter. This fitting or filter holder is attached to the condenser (106) by a thyme located on the side of the disc

(103), which also serves as an axis to remove and insert it and thus be able to put and remove the filter, in addition, just on the opposite side

of the axis thyme, the filter holder, usually has a tab in the form of a downward cylinder (104) to be able to operate it with the finger, and a rotation stop as a cylinder downwards in the condenser (105), just next to the thyme what does axis and

it holds the filter holder to the condenser, to limit the rotation and does not exceed the height of the filter holder downwards and that serves to make the light passage hole of the filter holder fit with that of the condenser light passage when it is closed until that stop. So far, aspects of the filter holder of the known microscopes have been described. The universal multiple compound filter holder for microscopes consists of two upper parts, figures 7,8.9 and lower figures 1,2,3,4,5,6 composed of several pieces, the upper part consists of several parts, see 12,13, 14 (Fig. 7,8,9) and the lower part also consists of several pieces, see 1,2,3,4,5,6,7,8,9,10,16 (Fig. 1, 2,3 , 4,5,6). The upper part and the lower part are joined by four magnets (6) of 1,4kg of load capacity each, which are glued to the immediately superior piece (1) because the composition of this is iron and less protruding of the half being immobile and guided by the design of the piece (2) that keeps them embedded, the rest of the pieces, except the bottom piece (13) of the upper part that is also iron, are all of light aluminum. Pieces 1 and 2, are joined with the two thymes 8 and 7 that pass through all the pieces of the lower part (fig. 4,5,6) (3,4,10) And that are screwed with their corresponding nuts, the which, in addition to joining these pieces, make one of shaft (8), for filter holder plates (3,4) and the other (7) of turning stop, for those same plates. Too,

the magnets (6) protrude from the upper part (1) almost half, so that the upper part (Fig. 12,13,14), when fitted in

that central circular hollow of the bottom, through four

holes (5) that guide the four protruding thymes (13) of the upper part that act as pins, apart from joining the pieces (12,13) of the upper part, it remains

glued by magnetization, the upper part to the lower one, thanks to the fact that, as we have said before, the piece (13) that touches the magnets

(6) is iron. We have already seen the way in which the upper and lower parts are glued by magnetization and guided in a position

concrete, quality that gives this filter holder a great versatility, since it can be combined, and an extraordinary maneuverability, in addition to training it to be adaptable to all filter holders, for filters with a diameter

minimum of 32mm, since, simply by changing the external diameter of the part 12 (Fig. 7,8,9), it could be adapted to any diameter of microscope filter holders, characteristic that gives it the condition of universal. Let's move on to why it can be put in the filter holder of the

. .

microscope. Thanks to the fact that the thickness of the piece 13 (Fig. 9) is greater than the thickness of the piece 1 (fig. 5), they penetrate at a distance from each other 1.5mm thick which is approximately the maximum universal thickness that we we will find in the construction material of the support ring of the filters of the filter holders of the standard light condensers (fig 10.11) (101) for microscopes, that is, placing the upper part (Fig. 8,) of the filter holder in question in the support ring of the filter holder (10 1) of the microscope condenser (Fig. 1 O), from which the part 13 of the upper part (Fig. 9) will protrude below, its thickness minus the thickness of the material construction of that ring (10 1), while the thickness of the filter holder ring material of the

condenser does not exceed 1.5mm thick do not open loss of

magnetizing power since parts 13 (fig. 9) and 2 (fig. l)

they will never be separated, also the wings (15) from the top

(Fig. 1) allow to avoid the screw (103) of the eccentric shaft of the

filter holder (10 1) of the microscope light condenser (Fig.

11.12) thanks to which it can be removed and inserted from the condenser, and

of the rivet (104) used as a tab to move it

protrudes down just on the opposite side.

We have already seen how it is placed in the filter holder of the

microscope light condenser, now we will see how it

They put the filters and patches.

First, let's understand how the filter holder plates are folded and deployed (Fig. 2) and the filters are rotated. Well, pieces 3 and 4 of the upper part are joined by a screw (9)

in the tab of its most extreme part that holds them together

in pairs and fastened by the screw (7) that acts as an axis for the

bottom located on the opposite side. These groups of two

pieces are separated by small washers (16) (Fig. 6) to

allow rotation without friction. The top of the turn for

plates are marked by the other screw (8) in front that makes

stop, top, maximum as a noun, top as an adverb. To insert a filter, we will open the filter holder plate

formed by the union of pieces 3 and 4 (Fig. 2), and we will put it

in the cavity marked by the circle, eccentric with respect to the

central circle of light passage (11), the diameter of the filter is

slightly smaller than the diameter of the eccentric circle of that

filter holder plate so that this feature allows you to rotate

within that eccentric circle with hardly any friction

just moving it slightly with your finger

by the part of the filter protruding from the eccentric cavity (3)

which is sectioned While light patches

they are supported by piece 13 (Fig. 8) that has a diameter of

inner hole, smaller than the outer diameter of the light patch and this in turn has the same outer diameter as the diameter of the inner hole of the piece 12 (Fig. 8), being perfectly fitted in the hole hole of the piece

from the top. From all the described and by the observation of the drawings the advantages of the universal multiple composite filter holder in question, with respect to other preceding embodiments, emerge. First of all, we must highlight its magnetization system that allows it to be placed and removed in a very simple way. In addition, the strength of the magnets, equivalent to a total of 5.6 kg that they could support, provides a stable and safe grip to interact with it in the movement of the filters. Secondly, we must also highlight the design of the filter holder plates that allow the filters to rotate with total smoothness 3600, facilitating the polarization of light and the emission of colors with polystyrene filters. In addition, thanks to the design of the upper part, it can be adapted to any size of filter holder, making it universal, and housing the light patches of the different lighting systems such as DIe Nomarsky (differential interference contrast), phase contrast, dark and oblique field or place it directly in the filter holder of the condensers of these types of lighting, demonstrating a total versatility. All this together offers the possibility of having in this universal multiple composite filter holder for microscopes a light patch and three filters that can be rotated 3600 and exchanged during observation simply using the mechanisms available, offering the possibility to enjoy

with a simple condenser of much more complex lighting methods.

Materials will be independent of the object of the invention.
