Dear List,
Please let me clarify CSUX1 filter requirements.
As for emission filters, you can use any commercailly available emission filters of 25mm diameter as long as they have appropriate wavelength range and enough blocking capability.
However, the dichroic (dichromatic) mirrors for the CSU heads(all CSU10/22/X1) have reverse charcteristics from those used for standard microscope.
Please imagine the location of the dichroic mirror in the CSU scanners, which is placed between the microlens array and pinhole array at about 45 degree angle. The excitation laser beamlets focused by the the microlens will pass through the dicroic mirror and then go through the pinholes. The emission light goes back the light path to the pinholes then reflrcted by the dichroic mirror to reach at the detector(CCD camera). So, please only use specific dichroic mirrors for the CSU heads. Also, the thichness of the dichroic mirrors should be 0.5 mm +/- 0.02mm(0.01mm is more desirable) for optimal light efficiency.
Please always feel free to directly contact Yokogawa for any questions.
Best regards,
Mizuho Shimizu

CSU-X1 is not using 45 degree dichomatic mirrors either, they also have
low-angle incidence ones. I am not sure about the precise angle, however,
these mirrors have to be produced and there are probably not so many
different low-angles out there (for Nikon, Zeiss, Yokogawa). But it might
make sense to ask Yokogawa for the correct angle.
