Abstract

The utility model discloses an eyepiece accessory for a microscope, which can be changed with an ordinary eyepiece and can be observed by two persons. The eyepiece accessory for a microscope comprises two eyepieces (8) (9) which are provided with pointers (6) (7), and the meeting part of the light paths of the eyepieces is provided with a beam splitter prism (1). The lower end of the eyepiece accessory for a microscope is provided with a connecting tube (5) which is sheathed on eyepiece sleeves of the microscope when in use; the light ray ascending from an objective is respectively reflected and transmitted by the beam splitter prism and then goes into the two eyepiece sleeves; so the eyepiece accessory for a microscope can be observed by two persons simultaneously. The pointers arranged in the eyepiece sleeves can point at the same observed detail after adjusted.

Description

Ocular accessory for microscope

The utility model relates to a kind of annex that eyepiece is housed that is used on the microscope.

Because observation biological cell commonly used, the microscope of tissue, no matter the monotubular or the bitubular, its eyepiece can only use for a people.When on two people need discuss or impart knowledge to students a certain observed details, needing to explain, just very inconvenient.Normally rely in the eyepiece by last hair pointer, mobile microslide makes pointer face toward the details that comes into question, and two people watch in turn, and solves with pen is delineated cooperation on paper way.Though aim at the microscope of teaching usefulness a few cover eyepieces are housed, but observe simultaneously for the number people, but can not explain thereby can not point to a certain details by dress hair pointer.Shang Youke is by the microscope of dress projection screen or TV camera, but they all are bulky, cost an arm and a leg, thereby use is severely limited.

The purpose of this utility model is that a kind of annex that eyepiece and pointer are housed will be provided, and it can, be installed on the simple microscope usefulness that supplies two people to observe simultaneously, discuss as the transposing eyepiece when needed.

The purpose of this utility model is achieved in that in this annex, is equipped with the Amici prism of plating reflective membrane on interior light path at the object lens image distance, can see through and reflection equivalent light.All put so that the eyepiece stalk of identical eyepiece to be housed on this sees through two light paths with reflection, in the tube pointer is housed, the distance of regulating the eyepiece eyeglass can make the pointer imaging clear.This structure of the present utility model can be seen identical resembling in two eyepieces, and pointer position can point to identical details after adjusting.The utility model is equipped with extend neck, can be installed on the microscope lens barrel.

The utility model relies on a certain details of seeing on the microslide, can use after adjusting to same image spaces two pointers are disposable.Each one regulates eyepiece during use, see that pointer resembles clearly after, regulate object lens again and make on the microslide sample imaging clear, so that observe.After using the utility model, the image distance of object lens has increased about 100mm than originally, thereby with the large-numerical aperture object lens time, should influence the sharpness of institute's imaging.Learn through actual tests, only the time with 100 times of oil immersion objectives, this phenomenon is more obvious, so under the situation of the original oily mirror imaging resolution of needs, can adopt the corrective eyepiece solve (Methodsin Microbiology.V.7B, P.288, edited by J.R.Norris and D.W.Ribbons, Academic Press, London and New York, 1972).The utility model can use Huygens or Ramsden ocular.As long as its lighting source is with the 40W incandescent lamp of a 220V voltage, reached limpid in sight when using oily mirror.

Obviously, the utility model is very useful, when needs, is contained on the simple microscope, and two people sit at one station one, can observe simultaneously and discuss.In addition, in middle school experiment, adapted it, equal to have increased a microscope, and be convenient to teacher and explain observed details.With it fit over the demonstration sample microscope on the time, also can make more observation of students.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is according to the sectional view of the discussion that the utility model proposes with the microscope ocular annex.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

This device comprise one include an Amici prism (1) connect volume (2), its volume wall and upper and lower end opening part connect with sidelong glance lens barrel (3) last eyepiece stalk (4) and extend neck (5) respectively.Adjusting volume (8), (9) that the eyepiece eyeglass is housed are enclosed within and rely on screw thread to form scalable connection on the eyepiece stalk.Two eyepiece stalks respectively are equipped with pointer (6), (7), and wherein the supporting pieces (10) at pointer (6) place heads on and is exposed at the outer adjusting screw (11) of eyepiece stalk and (12), is used to regulate the position of pointer.The cemented surface of Amici prism (13) contains reflective membrane, can reflect and the light that sees through equivalent.Dismountable balance plate (14) is contained in the offside of sidelong glance lens barrel, so that when using on the microscope of lens barrel skew back, the sidelong glance lens barrel is reason gravity and sagging not.

After passing extend neck (5) from the light of micro objective, reflect and the light that sees through, appear the eyeglass of regulating on volume (8), (9) respectively, and can be observed through cemented surface (13).Time spent rotates earlier to regulate to roll up and makes pointer (6) and (7) imaging clear, regulating micro objective then makes on the microslide sample imaging clear, adjusting screw (11), (12) overlap the needle point of two pointers on a certain details of seeing again, at this moment just can use.Two pointers also can manage to aim at after gummed or welding are fixing, and the way that does not adopt adjusting screw to adjust.

Claims

1, on microscope, can discuss and use the eyepiece annex with two people that common eyepiece transposing is used, this annex have one include an Amici prism (1) connect volume (2), its upper end, the opening part of lower end and the volume wall on respectively correspondence connect above eyepiece stalk (4), extend neck (5) and sidelong glance lens barrel (3), every eyepiece stalk (3), (4) all overlap the adjusting volume (9) that has only the eyepiece eyeglass with, (8), it is characterized in that every eyepiece stalk (3), a pointer (7) respectively is housed (4), (6), two pointers (7), (6) position is the same some of their elephants of all indicating same observed object.
