Claims

[Claims for Utility Model Registration] In a specimen fading prevention device for an epifluorescence photometry microscope, the device is provided between a light source and an excitation filter, and is normally in the first state to reduce the brightness of the illumination light. a variable device that almost instantaneously changes to a second state to increase the brightness of illumination light by inputting a switching signal; and a variable device that changes to a first state almost instantly by inputting a second switching signal; a command device that generates the first switching signal in response to an external command; and a device that generates a photometry start signal when the variable device changes from a first state to a second state after the first switching signal is generated. , a photometry device that starts photometry in response to a memorized photometry start signal and ends photometry after a certain period of time;
A fading prevention device comprising: a device for outputting a second switching signal;
