LECO for Empowering Results
Schott VIS Scratch-Resistant (hard) AR Coating
Categories: Ceramic; Glass; Optical

Material Notes: Spectral range 450-700 nm

Using magnetron sputtering and Schott's process for hard AR coatings results in both scratch resistance and AR characteristics (also for different angle of incidence possible). Dimensions: Up to 590 x 730 mm and thickness < 40 mm

Proof of scratch resistance: Scratch resistance is often measured after performing the so-called Bayer test (often as variation of the original test in ASTM F735) where the hard AR-coated substrate is covered by sand and oscillates many thousand of times with several hundred rounds per minute. The optical performance (e. g. reflection) is measured before and after the Bayer abrasion test.

Information provided by SCHOTT.

Available Properties
  • Thickness
  • Reflection Coefficient, Visible (0-1), before abrasion test
  • Reflection Coefficient, Visible (0-1), after abrasion test
