MidOpt - LP900 Near-Infrared (IR) Longpass Filter

The MidOpt LP900 Near-Infrared (IR) Longpass Filter sharply blocks light below 900nm while allowing longer wavelengths to pass. The LP900 is a great option when viewing reflected 915nm laser diode light. These filters can also be used in infrared digital photography as detector windows and in various scientific and forensic applications. For example, images of blood stains or gun shot residue on dark-colored fabrics or denim can often be enhanced by causing the fabric to appear white or much lighter when the LP900 is used over a camera lens that has its IR blocking filter removed. MidOpt Longpass Filters have a broad, Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths, are double-side polished for exceptional parallelism and optical flatness and are anti-reflection (AR) coated to limit glare and minimize reflection loss.
