Broad Band AR coated windows (BBAR)

Features

These coatings are designed to increase the transmission over a broad spectrum

Description

Broad Band AR coatings designed to reduce the reflectivity of a component to near-zero for Broad band wavelength range.

We suplly standard Broad Band AR coatings in the range 0,19 um 10,6 um.
These multilayer broadband anti-reflective coating can higher transmission access a broad spectrum. Therefore, it is the ideal for a wide range of multi-wavelength laser and white light applications. Please notified that the wavelength range and reflectivity of the coating changes according to the angle of the incident beam.

Coatings are provided by Ion Beam Sputtering (IBS) or Electron beam evaporation with/without Ion assistance coating techniques.
