Materials: alpha-BBO or Calcite single crystal.
Optically cemented structure.
Large length/aperture ratio for wide acceptance angle.
High extinction ratio (>100,000:1) over a large wavelength range.
Minimal beam displacement and angular deviation for
the transmitted beam.
Suitable for low power applications.
Housing OD: 1" (25.4 mm) or 30 mm. OD 2" available upon request.
