Overview

Flexible Beam Steering: High Reflectivity Maintained Across 0-45° AOI

The VLGLM/VLQLM Series is a high-performance laser mirror designed for versatility in complex optical setups. Unlike standard mirrors optimized for a single angle (e.g., 45° only), this series features advanced dense dielectric coatings that maintain exceptional spectral performance at any Angle of Incidence (AOI) from 0° to 45°.

This wide-angle insensitivity makes it the perfect solution for laboratory optical construction and industrial laser alignment. Whether you are steering a beam by 90° (45° incidence) or performing fine angular adjustments, these mirrors deliver >99.5% (up to 99.9%) reflectivity, minimizing energy loss and preventing thermal buildup.

Available in both K9 (N-BK7 equivalent) and UV Fused Silica substrates, these mirrors are optimized for common laser lines including Nd:YAG (1064nm, 532nm) and Ti:Sapphire (700-900nm).
