Broadband Anti-Reflective Coating ARB 1 IR

Hard and scratch resistant anti-reflective coating to reduce reflection losses and increase transmission for the IR spectral range
Residual reflection < 1 % for angles of incidence 0° ≤ AOI ≤ 15°
Damage threshold H_∞ > 30 J/cm²at 1064 nm with 11 ns laser pulses (s-on-1) at 10 Hz (Substrate: fused silica)
Design adaptable in the spectral range of 1000 nm ≤ λ ≤ 5000 nm and for higher angles of incidence
Bandwidth: between 20 % and 50 % of design wavelength with R < 2 % depending on substrate material
Substrates: sapphire, silicon
