MidOpt AC685 Acrylic NIR Longpass Filter
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. To view this alternative C-Mount option, click here.
