Optical Versatility

This large, oval-shaped dielectric mirror is a highly specialized optical component that offers dual-functionality based on the Angle of Incidence (AOI):

1. At 45° Incidence:
  • Acts as a High Reflectivity (HR) mirror for the IR range (750 - 900 nm), with R > 99%.
  • Acts as a Beam Splitter for He-Ne lasers (632.8 nm) with a Ratio R/T = 40/60.
2. At 0° (Normal) Incidence:
  • Acts as a High Reflectivity (HR) mirror for 840 - 1060 nm.

The mirror features a multi-layer dielectric coating and a precision oval shape with a professional mounting bevel, making it ideal for large-aperture IR applications or beam steering setups.
