PALATINE, Ill. — Midwest Optical Systems Inc. has announced the LP900 Near-IR Longpass Filter for use with 915 laser diodes.
The LP900 filters sharply block light below 900 nm while allowing longer wavelengths to pass. The devices are ideal for viewing reflected 915-nm laser diode light.
The filters can also be used in IR digital photography as detector windows, as well as in various scientific and forensic applications. For example, the LP900 filters can enhance images of blood stains or gunshot residue on dark-colored fabrics or denim.
