Product Family Description

UV Fused Silica Substrates with a 30 Arcminute Wedge
λ/10 Surface Flatness and 20-10 Surface Quality
Prevent Laser Instability When Used in Laser Cavities
N-BK7 Wedged Windows and Fused Silica Flat Windows Also Available

TECHSPEC® Fused Silica Wedged Windows are manufactured from UV grade fused silica and feature a 30 arcminute wedge. The wedge of these windows eliminates Etalon effects by preventing back surface reflections from traveling along the same optical path as the transmitted beam. This protects against laser instability, mode-hopping, and power spikes when used in laser cavities and beam interference effects when used externally. TECHSPEC® Fused Silica Wedged Windows are ideal for use in UV or high power laser applications due to their high UV transmittance and insensitivity to temperature variations. These windows can also be used as beam pick-off optics or beam samplers to monitor laser beam properties such as beam power over time.
