AC900-49 | AC900 Acrylic Short-Wave Infrared Longpass Filter

Part: AC900-49

Diameter: M49 x P0.75

The MidOpt AC900-49 AC900 is a stock IR Pass/Visible Block acrylic sheet material that blocks a large portion of the near IR spectrum. Both surfaces are hard-coated for scratch resistance. It is ideal for use with 940nm LED illumination or in other semi-covert situations where visible light emitted by arc/flash lamps needs to be blocked while IR illumination is passed. AC900 material is custom cut from 2mm thick sheet material according to customer specifications and is supplied with protective overlays on both surfaces. 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.
