Optical Filter, Laser Line, 12.7 mm, 780±3 nm Center, 20±3 nm FWHM
The 05LF20-780 Laser Line Filter is 12.7 mm diameter with a center wavelength of 780 ± 3 nm, and full width half max of 20 ± 3 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. Specifications
