25° Diffusing Angle, 5mm Sq., Wide Angle Diffuser

Product Details 25 and 125° Diffusing Angles Available 90% Transmission Efficiency Eye-Safe ROE, No Zero-Order and No Hot Spot Wide Angle Diffusers are used to create diffused top hat beam profiles in one dimension and are available in angles of 25 or 125°. These diffusers can be easily paired for diffusion in two dimensions for square or rectangular output profiles with a steep edge slope and high homogeneity. These diffusers have increased transmission efficiency and uniformity versus standard ground glass diffusers. Wide Angle Diffusers are an eye-safe refractive optical element (ROE) with no zero-order and no hot spots. These diffusers are ideal for integration into LIDAR, heads up displays (HUDs), time of flight, 3D sensing, and machine vision applications. Note: These are designed for use with collimated light with a minimum beam size of 2.5mm FW/e². Use with diverging beams or beam arrays will change output profiles. Specifications General Type: Flat Top Diffuser Note: Recommended M 2 >10 and beam size >2.5mm FW/e 2 for best homogeneity and steep slopes Physical & Mechanical Properties Clear Aperture CA (mm): 4.5 x 4.5 Dimensions (mm): 5.00 x 5.00 ±0.1 Thickness (mm): 0.50 ±0.05 Optical Properties Diffusing Angle (°): 25 Coating: Uncoated Substrate: Many glass manufacturers offer the same material characteristics under different trade names.
