High Performance Off-Axis Parabolic Mirrors


  • High Quality Glass Substrate
  • λ/4 or λ/2 Surface Accuracy
  • Ideal for UV and Visible Applications

Our High Performance Off-Axis Parabolic Mirrors feature a superior surface accuracy glass substrate, making them ideal for UV and visible applications. Unlike standard parabolic mirrors, these off-axis mirrors direct and focus incident collimated light at a specific angle, allowing unrestricted access to the focal point. Typical applications include use in Czerny-Turner and Littrow spectrometer configurations, and in general collimator and beam expander setups.

High Performance Off-Axis Parabolic Mirrors have been replicated from masters which have passed stringent inspection criteria, including zonal interferometric and Foucault testing. The aspheric optical profile is holographically recorded onto the mirror substrate.
