Fused Silica-JGS2
Optical Grade Fused Quartz (JGS2) provides good UV and visible transmission. It has almost the same physical and
chemical properties with JGS1. However only in thin & small sheet pieces, JGS2 is virtually bubble-free. Elements
built from larger pieces will most likely contain bubbles, so application should not be sensitive to these inclusions.
But in cases where simple light gathering and strong mechanical properties are the primary goals, JGS2 grade
provides excellent performance at a low price.  Ideal Applications for JGS2:  
● Condenser optics not concerned with scatter or distortion
● High temperature and pressure applications
● Optical flats, microscope slides and sight glasses
