These colour glass filters are mounted in high quality black anodized rings for easy integration into aesthetic lighting, imaging and cosemetic laser applications. Our extensive filter range includes long pass, short pass and band pass types over a broad range of wavelengths.

Our camera filter mounts are designed to stack with each other enabling several filters to be used together. Two or more filters can be overlapped in order to create unique spectra that would not otherwise be possible with a single filter. Mounts can be custom designed to fit individual applications. Each mount is made from sturdy aluminium and the filter is supplied mounted in place via a fitted locking ring.

For more information on our stock mounted filters, or to enquire about our custom capabilities, please contact our technical sales team.
