Antireflection Coatings


ANTIREFLECTION / INDUSTRIAL / INFRA-RED / DIELECTRIC / LASER / METALS


The solution to the problem of unwanted surface reflection from various glass and other optics. By increasing the transmitted visual energy in multi-element optical systems and maximizing resolution by maintaining a sharp, crisp image throughout. These dielectric coatings are extremely durable with high damage threshold and provide state-of-the-art performance when used in diverse environments.

Magnesium Fluoride (MgF2)

  • Meets MIL-C-675 durability requirements.
  • May be centered at any chosen wavelength between 250nm and 4000nm.
  • The effective band width will vary as the wavelength range shifts from near UV to Visible to IR.
  • While the coating will withstand diverse environments, some substrate types may fail this exposure.

BroadBand Antireflection (BBAR)

  • The coating of choice when maximum trans-mission is desired over a wide bandwidth.
  • Meets MIL-C-675 and MIL-C-14806 durability requirements.
  • May be centered at any chosen wavelength between 250nm and 2000nm.
  • The effective band width will vary as the wavelength range shifts.

V-Coats

  • Designed to optimize transmission at one specified wavelength, with an effective bandwidth of +/- 20nm in the visible, +/- 5nm in the UV,
    +/- 40nm in the IR.
  • Near-zero reflectance at one specific wavelength and angle of incidence. Maximum reflectance often less than 0.2% typical reflectance at 0.1%
  • Standard coatings available for most laser lines.
  • Custom center wavelengths at specific angles of incidence available on request.
