High energy parallel windows are made with low-scatter excimer grade UV Fused Silica and optimized for high power Nd:YAG laser systems. Each surface is coated with a high efficiency, high damage-threshold antireflection coating.
High efficiency, high damage threshold, Laser Line V-Coatings
Excimer Grade UV Fused Silica for excellent thermal stability
<5 arc-second parallelism
Fine low-scatter surface with 10-5 scratch-dig surface quality
Each surface of our High Energy Parallel Windows is coated with a high efficiency, high damage threshold V-coating. Coatings are available to maximize transmission at 1064nm, 532nm, 355nm and 266nm, corresponding to the 1st, 2nd, 3rd, and 4th harmonics for Nd:YAG lasers.
High Precision Manufacturing
These high energy parallel windows are manufactured to the highest precision with flatness up to λ/10 for low distortion and < 5 arc second parallelism for exceptionally low beam deviation.
Low Scatter
Our high energy parallel windows are made with the finest quality excimer grade UV fused silica material for extremely low bulk scatter and autofluoresence. These optics boast a high quality surface of 10-5 scratch-dig for very low surface scatter.
