Wondering about being able to mounting a COTI style device on an Anvis objective

The mount rings have some adjustment but can the clamp to the very front? Would any device have clearance issues with the Anvis nubs?

Has anyone here done it or seen it done?

Thanks

BUT......

ANVS objective lenses being what they are (for aviation) filter certain wavelengths of light that are used specifically in NV compatible cockpit lighting and this can render the COTI useless or diminish its performance. Most of the ANVS lenses floating around on the commercial retail market are unknown in terms of which type they are. Unfortunately, most folks including many resellers aren't even aware there are different types of filters (A,B,C). I've seen guys with two different filter types (A & B for example) on the same goggle

The safest bet is to assume your lenses will filter all light below 665nm (all colors from red to green).

If you can test the COTI pre-purchase then it's worth trying it to see if it is compatible as there are exceptions depending on the lens.

ETA: Yes, you can "test" different color lights but in my experience with these lenses you need to test with the actual display that will be used.

Thanks for the info I had no idea about the light filtering aspect I just kinda ended up with this device because I got a good deal on it lol

Seems like it won't be worth the trouble I'll get something different before I think about getting one
