General laser microscope filter

In the common laser microscope, the wide field light source and the laser light source have different requirements for the filter, which are mainly shown in the following aspects:

1. The laser has good monochromaticity and requires a narrow band of excitation plates;

2. Generally, experiments have certain requirements for the quality of the reflected laser beam. The dichroic mirror used needs better flatness to minimize the wavefront reflection distortion of the laser;

3. The laser energy density is high, and the emitter needs a higher cut-off depth (OD value) to reduce the excitation noise of the laser.
