MidOpt - LP665 Dark Red Longpass Filter
SKU: LP665-25.5
The MidOpt LP665 Dark Red Longpass Filter is recommended for night vision applications using a filtered broadband light source. The LP665 blocks most visible (VIS) light while passing deep red and near-infrared (IR) wavelengths. If the application required blocking IR light for easier subject matter recognition, the MidOpt BP660 is recommended. 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.
