where to buy an IR filter from?

[orangefish 0]

Hello everyone,

 

I am looking for an IR filter (to cut visible wavelengths). The camera I want to use it on does not have a C or CS mount and the only way, as far as I see it at present, is to place a 48 mm diameter filter along with the glass covering the lens.

 

So, what are recommended places from where I can order a 48 mm, 1 or 2 mm thick, IR filter (similar to Hoya R72, which all wavelengths shorter than 720 nm)?

 

Thanks in advance.
