IR cutoff filter glass

[caseymessick]

We're looking for glass that can be used to filter out any infrared radiation. We will be working with CMOS images, and so prefer reflective filtering. We're still in design stages, but need a material that would be work for the glass, so we can start designing the manufacturing process (which will change dependent on the strength of the glass). Appreciate any quick feedback

Thanks!

What do you mean by "infrared?" NIR, SWIR, MWIR, LWIR?

What do you mean by "glass?" and "reflective?" The latter and the former don't tend to go together.

Since you mentioned CMOS imaging, try sticking this in Google:

infrared cut-off filters reflective cmos

Manufacturers typically list their materials and coatings in the data sheets. Here's the first hit you'll get:

Or, contact these folks and speak with their tech support:

Be prepared to answer IRstuff's question about wavelengths.

There's also a good one inside every day/night security camera out there if you want to see how it's been done for many years.

Best to you,
