40-Degree Mercury Systems Light Shaping Diffuser

These Mercury Systems / Physical Optics 40-, 60-, 80-Degrees Series Light Shaping Diffusers have a surface that is holographically replicated on polycarbonate from a holographic master. They have a surface with completely random, non-periodic structures that can be thought of as randomized micro lenslets. They cause light to diverge at up to the filter's specified cone angle. The random size and orientation of the structure eliminates both wavelength dependent effects and moiré interference effects. They will work with both polychromatic and monochromatic light that is either coherent or incoherent. They work best with collimated light but also work well in non-collimated light, albeit emitting somewhat wider than the nominal angle.

Hot spots and uneven light distribution are common problems with most light sources, including filament lamps, arc lamps, LEDs, cold cathode fluorescent lamps, fiber optics, and lasers. Light Shaping Diffusers smooth and homogenize these sources while providing uniform light in critical applications. The energy distribution from these diffusers closely approximates a flat top distribution across the specified range of angles. Diffusers are manufactured in both circular and elliptical beam patterns. Large angle diffusers produce the greatest degree of homogenized light.
