Metallized Plate Beamsplitters
- The thin metallic film acts as broadband partially transmitting mirror
- Substrates polished both sides to λ/10
- Wedged substrates (for ghost suppression) are also available as standard
- Standard diameters from 25.4 to 100mm
These beamsplitters provide a highly neutral reflectivity over the visible spectrum and are most useful for broadband or tunable wavelength applications. A separate coating, optimized for use at the near-IR diode wavelengths, is available.
