Abstract
The utility model relates to a fall radio fluorescence light path tube for microscope which is used for a fall radio fluorescent microscope, comprising a converging barrel, a light splitting chamber and various glasses which are assembled in the converging barrel and the light splitting chamber. The first lenticular sheet in the converging barrel is made of transparent ultraviolet quartz glasses, and each excitation filter, auxiliary excitation filter or two-way colour-separating glass of the converging barrel and the light splitting chamber is respectively plated with a rigid filming layer. The utility model has a strong brightness and long service life, working in dark room condition is not needed, and the mirror checking effect is markedly raised.
Description
The utility model relates to that a kind of epifluorescence microscope device uses falls to penetrating fluorescence light path tube.
Because fluorescence microscopy is applied to microscopic examination device, has developed the epifluorescence microscope device, carry out the microscopy research work so carry out the utilization fluorescence microscopy just gradually in each scientific research department.Particularly the practicality in medical domain more makes it use and has a distinctive style.But, because of removing, existing epifluorescence microscope device costs an arm and a leg, outside the defectives such as need be worked under dark room conditions, and serviceable life is short, its structure also exists some to wait improved problem, all adopting ordinary optical glass to add heat-protecting glass as first lens in the light collecting barrel that joins with lamp house forms, this lens arrangement not only because of lamp house mercury lamp temperature height, easily makes lens burst, and heat-protecting glass increases the loss of light, approximately loss 40% influences luminance brightness.Used exciter filter, auxiliary exciter filter and two-way color separation eyeglass all adopt mantle method plated film, and this limit diaphragm can not wiping, and transmitance is low, and diaphragm easily comes off, and serviceable life is low, influences fluorescent brightness, is unfavorable for applying of fluorescence microscopy.
The purpose of this utility model provides a kind of improved microscope and falls to penetrating fluorescence light path tube, and its light is strong, and long service life need not to work under dark room conditions, significantly improves the microscopy effect.
The purpose of this utility model is achieved in that this device is in addition improved on the light path tube basis in existing epifluorescence microscope device.The light path tube comprises lens, exciter filter, the auxiliary exciter filter that is assembled in the light collecting barrel and is assembled in the lens in the light-splitting chamber, auxiliary exciter filter, two-way color separation eyeglass, additional cutoff filter, cutoff filter, wherein first lens in the light collecting barrel adopts the outer quartz glass of transparent violet to make, and is coated with the hard coatings on each exciter filter in light collecting barrel and light-splitting chamber, auxiliary exciter filter, the two-way color separation eyeglass respectively.
Because the utility model is improved to form on existing light path tube basis, so be easy to realize.Adopt the outer quartz glass of transparent violet to get first lens that combine for by ordinary optical glass and heat-protecting glass, both simplified the structure of lens, make lens not be subjected to temperatures involved again and burst, reduce light loss, light is strong, has improved light path tube serviceable life.Used various exciter filters, auxiliary exciter filter, two-way color separation eyeglass all are coated with the hard coatings, and rete is firm, is not afraid of wiping, does not come off, and the transmitance height significantly improves visibility factor, by effective.Because each plating sheet adopts hard coatings, and the excitation light flux is strengthened, the fluorescence volume that is excited also obviously increases, and light is strong, makes background and image appropriateness, clear, thereby the rate of distinguishing be improved (positive rate height).Because of the improvement of said structure, the brightness of the utility model light path tube is significantly strengthened, adopt the epifluorescence microscope of this light path tube to work under the dark room conditions, as long as get final product microscopy in dark place, bright chamber.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the concrete structure longitudinal sectional view of the utility model light collecting barrel.
Fig. 2 is the concrete structure transverse sectional view of the utility model light-splitting chamber.
Describe concrete structure of the present utility model in detail according to Fig. 1-2.This device comprises light collecting barrel 1 and light-splitting chamber 5 and assembles its each interior lens set.Wherein the structure of light collecting barrel 1 and light-splitting chamber 5 is with the light path tube of prior art, just first lens 2 of its light collecting barrel 1 adopts the outer quartz glass of transparent violet to make, rather than ordinary optical glass adds the array configuration of heat-protecting glass, simplified manufacturing process, the saving of labor, saves time.Eyeglass in light collecting barrel 1 and the light-splitting chamber 5, as the auxiliary exciter filter 3 on the auxiliary horse, the exciter filter (not drawing among the figure) that install junction between light-splitting chamber 5 front ends and light collecting barrel 1, fall to penetrating eyeglasses such as the two-way color separation eyeglass 8 in the light tube, auxiliary exciter filter 9, all be coated with the hard coatings.Excite the exciter filter 4 on the light quantity arm-tie, additional additive filter 6 on horse, the coloured optical glass of employing high-quality such as cutoff filter 7 that fall to penetrating in the light tube are made.It has overcome in the prior art eyeglass plating limit diaphragm effectively can not wiping, serviceable life low defective, rete is firm, erasable, long service life, the transmitance height, light is strong.
