Original Press Release:

TECHSPEC® λ/20 UV Fused Silica Right Angle Prisms Tailored for Precision Laser Applications

UV Fused silica substrate offers extended range deep into the UV

Edmund Optics® (EO), the premier provider of optical components, introduces new TECHSPEC® λ/20 UVFS (Ultraviolet Fused Silica) Right Angle Prisms. The versatile UVFS prisms feature precison specifications to meet the most demanding applications. They are ideal for beam steering, retroreflection, or any application where low wavefront error is critical to system performance. The UV fused silica substrate exhibits low thermal expansion and excellent transmission from the UV to the NIR spectra.

Industry-leading ±15 arcsecond angular tolerance

TECHSPEC® λ/20 UVFS Right Angle Prisms are designed for laser applications with a surface flatness of λ/20 and surface quality of 20-10. These laser optic quality prisms feature an industry-leading ±15 arcsecond angular tolerance for guaranteed control of the optical path. They are specially polished using highly refined processes to ensure the flatness of the prism faces. These RoHS compliant prisms are uncoated and have a clear aperture of 90%. Six models are available with legs measuring from 5mm to 25mm long and hypotenuse measurements from 7.1mm to 35.4mm long. TECHSPEC® λ/20 UVFS Right Angle Prisms are in-stock and available for immediate delivery.
