UVFS Optical Wedge, Ø50.8 × 5.0 mm, 3°

Overview

High-precision transmissive optical wedge made from UV-grade fused silica (UVFS 7980 OF), offering excellent optical homogeneity, low absorption loss, and good environmental stability across the ultraviolet to near-infrared range. The precisely controlled wedge angle on both surfaces eliminates the interference fringes (etalon effect) caused by parallel plates and produces a small, controllable beam deflection. An optional 2D precision adjustment mount is available for convenient alignment and mounting on standard optical tables or optomechanical systems.

Applications

• Femtosecond / picosecond laser systems
• Interferometry
• Nonlinear optics experiments
• High-stability beam-path alignment

Storage & Handling

Store in a clean, dry environment at 25 °C and 40–60% relative humidity. Handle with lint-free materials and avoid mechanical contact with the optical surfaces. If a surface becomes contaminated, gently wipe it with ≥99% alcohol and lint-free lens tissue; do not use coarse cloth, water, or cleaners containing abrasive particles.
