New Diffractive Lens Array Diffusers from Holo/Or

Various laser applications require precise and efficient diffusers at low angles. Holo/Or’s new diffractive lens array diffusers have total (<10-5) ROC accuracy and feature diffraction efficiencies of ~ 95%, with no dead zones between the lenses. Due to their thinness and diffractive nature, they are not affected by thermal lensing and other temperature-related effects. They … Continue reading
