T-BBD1-E03 - Ø1" Broadband Dielectric D-Shaped Mirror, 750 - 1100 nm

E03-Coated Broadband Dielectric D-Shaped Mirrors offer >99% average reflectivity over the 750 - 1100 nm spectral range. Although broadband coatings offer smaller operating wavelength ranges than metal mirrors, they typically yield higher reflectivity in those ranges than their metallic counterparts.

The plot to the right shows the measured reflectivity of this coating as a function of wavelength. The shaded region denotes the range over which we recommend using these optics. Data was obtained using at a 45° angle of incidence.

  • Choose from Nine Coatings:
    • UV-Enhanced Aluminum: 250 - 450 nm
    • Protected Silver: 450 nm - 20 µm
    • Ultrafast-Enhanced Silver: 750 nm - 1000 nm
    • Protected Gold: 800 nm - 20 µm
    • MIR-Enhanced Gold: 2 μm - 20 μm 
    • -E01 Broadband Dielectric Coating: 350 - 400 nm
    • -E02 Broadband Dielectric Coating: 400 - 750 nm
    • -E03 Broadband Dielectric Coating: 750 - 1100 nm
    • -E04 Broadband Dielectric Coating: 1280 - 1600 nm
  • Choose from Ø1/2" or Ø1" Versions
  • Ideal for Use with Closely Spaced Beams
  • Reflective Coating Beveled 0.1 mm at Straight Edge
