MidOpt AC850 Acrylic Near-IR Longpass

AC850 is similar to AC800 IR Pass/Visible Block acrylic sheet except that it blocks further into the near IR. It is available both with and without scratch-resistant hard coating and is very well suited for use with 880nm and 940nm LED illumination, or in situations where visible light emitted by arc/flash lamps needs to be blocked while near-IR light is passed. AC850 material is custom cut from 3mm thick sheets according to customer requirements and is supplied with a removable protective overlay material. Orders for AC850 material are most often shipped “next day”. Other thicknesses are available on request.
*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.
