Filtering foil for 730 - 1000 nm

    Hi all, I have a system sensitive to VIS and NIR. I would like to apply foil(s) onto the windows of the system to filter out the wavelength range of 730 - 1000 nm. I still want to be able to look into the system through the windows, but a partial transmittance is ok.

    I noticed that standard sun-light control foil only filters properly > 900 nm, and I would like to add a semi-transparent blue foil.....

    Does anyone here know of specific products / suppliers, or have had some user-experience with semi-transparent foils ?

    Thanks :smile:
