MidOpt AC800 Acrylic Near-IR Longpass
AC800 Acrylic Near-IR Longpass Optical Filter is similar to AC760 IR Pass/Visible Block acrylic sheet except that it is protected with a scratch-resistant coating and blocks an additional portion of the near IR. This material is ideal for use with 850nm laser diode or LED illumination, or in situations where glass covers or filtering are not permitted (e.g., FDA or EFSA-regulated inspection applications). AC800 material is supplied with removable protective tape on both surfaces and can be custom laser cut from 3mm thick sheet material according to customer specifications. Next day shipping is typical. 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. To view this alternative C-Mount option, click here.
