Midwest Optical AC685 Acrylic NIR Longpass Filter, 710-1100nm Range, With StablEDGE
AC685 IR Pass/Visible Block filter material is 2mm thick acrylic sheet with carefully controlled near-IR spectral properties. It can be laser cut according to customer specifications, and is typically mounted over full spectrum UV/Visible/IR lamp-based lighting to ensure that (mainly) infrared light reaches the subject while otherwise distracting visible light is effectively blocked.
*Not available in 1mm thickness or standard 25.4™ C-Mount option. For filters thicker than 1mm, we offer an alternative mounting solution that has an overall thickness of 5.5mm. This mount can accommodate filters up to 3.5mm thick.
