Anti-Reflective Coating

Glass and Fused Silica Zero-Length viewports are available with an optional anti-reflective coating. AR coatings increase the transmissive characteristics of the optic by almost completely removing any reflective losses from both surfaces. Three standard A/R coatings are available: 780nm, 1064nm, and 780-1064 Broad-Band coating. When ordering specify “AR” followed by the bandwidth after model number (Example: VP-150-F2-AR780-1064). 

Features:

• Standard A/R coatings available:
  • 780 nm
  • 1064 nm
  • 780-1064 Broadband
• AR coating at 780nm and 1064nm transmission 99.5% minimum
• 780nm - 1064nm broadband transmission 99% minimum
• 200°C Maximum bakeout temperature
• Custom coatings available on request.

Larson Electronic Glass offers anti-reflective coatings as an option for zero-length glass viewports. 780nm, 1064nm, and 780-1064nm broadband are standard coatings. Custom coatings and coated fused silica viewports are also available on request.

NOTE: Price of viewport is not included in the AR coating price. AR coating prices only apply to Zero-Length 7056 glass viewports which must be ordered separately in addition to the coating charge.
