"Built in" cut filter on ASI Cameras?

Mr_Cellophane

Hi folks
So I have an ASI6200mc, but this question goes for the asi's in general. Where cna I find information on what range of light on the spectrum is actually hitting the sensor? implying that I'm not using any other external filter. Do the camera have a built in cut for UV or IR? Or do they have certain ranges filtered out? Does it differ from Camera to Camera? I can't find this on the website and I'm curious because I'm thinking that any Luminance or Light pollution filter I buy would just be totally useless as the camer aitself has already cut out a specific range.

Mr_Cellophane You can find the specifications in the manual,
The protective window of ASI6200MC Pro is UV IR cut.

Mr_Cellophane

Tech@ZWO Thanks so much!! You say it's UV and IR, but only IR is listed here....is it implied that it's UV as well?

Tech@ZWO

Mr_Cellophane Yes, it's UV IR cut

Be careful what ZWO tells you. Here is what I measured (using the ZWO D60 window that they sell to represent what they use in their cameras):

Install an extermal UV cut filter, or one of the many filters that I tested above.

BTW, there is a typo, as pointed out by TomasK, the head of the table should say 365nm instead of 465nm.
