Product Family Description

  • High Quality Fused Silica Substrate
  • <10Å Surface Roughness for Low Scatter
  • 90° Offset Angle for Easy Integration

TECHSPEC® High Performance Fused Silica Off-Axis Parabolic (OAP) Mirrors feature a surface roughness of less than 10Å which is the lowest scatter available in an off-the-shelf solution. Featuring a fused silica substrate, these low scatter alternatives perform better in the UV wavelength range than traditional metallic substrate OAPs. These mirrors are coated with broadband dielectric coatings for enhanced performance across the UV, VIS, and NIR spectrum. TECHSPEC® High Performance Fused Silica Off-Axis Parabolic (OAP) Mirrors are ideal for Schlieren, MTF, and Czerny-Turner and Littrow spectrometer systems due to their low scattering.

Note: Uncoated options require a coating for use. Contact us for a custom coating quote for your specific wavelength.
