AC850-77 | AC850 Acrylic Near-IR Longpass Filter

The MidOpt AC850-77 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. All MidOpt filters can also be purchased unmounted and in custom dimensions upon request from Machine Vision Direct.
