12.5mm Dia. 2.5° Beam Dev. Fused Silica Wedge Prism Uncoated

Product Details Deviates Laser Beam Path from 0.5° – 5.0° Ideal for UV to NIR Beam Steering Applications from 250 to 1064nm Ideal for High Power Beam Steering Applications TECHSPEC Fused Silica Wedge Prisms are designed for a range of laser beam steering applications requiring UV-VIS or first through fourth Nd:YAG harmonic Anti-Reflection Coatings. They are optimized to ensure the highest level of system performance using tightly controlled specifications including λ/10 surface flatness, 20-10 surface quality, and a wedge tolerance of 15 or 30 arcseconds. The Nd:YAG coated versions feature high transmittance and guaranteed laser damage thresholds specific to the design wavelength. TECHSPEC Fused Silica Wedge Prisms utilize a wedge design to deviate laser beam path from 0.5° – 5°. By creating a risley prism pair using two wedge prisms with the same ray deviation, custom beam steering up to two times the wedge deviation is possible. A low coefficient of thermal expansion ensures accurate beam steering in high power laser applications. Note: Power Diopter is defined as 1cm deviation at a distance of 1m from the prism. TECHSPEC Wedge Prisms are also available in N-BK7 versions .
