Laser Line Filter, 25.4 mm, 694.3±2 nm Center, 11±2 nm FWHM

The 10LF10-694 Laser Line Filter is 25.4 mm diameter with a center wavelength of 694.3 ± 2 nm, and full width half max of 11 ± 2 nm. It is optimized to block X-ray to Far IR wavelengths. Laser Line Filters are ideal for transmitting laser light while suppressing ambient light. The center wavelength shifts linearly with temperature less than 0.02 nm/°C. The highly reflective side of the filter should generally face the source, minimizing the thermal load on the blocking glass and epoxies.
