Medium diffusers are used for general applications. Wide diffusers are used for source arrays, ring lights, backlights, and rear display screens. Laser Line Filters 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.
