The 05LF10-325 Laser Line Filter is 12.7 mm diameter with a center wavelength of 325 ± 2 nm, and full width half max of 10 ± 2 nm. It is optimized to block 100 to 2000 nm 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.
