It has intensive OH absorption band in the interval of wavelength 2600-2800 nm. JGS1 is used for optics operating in the deep UV and the visible wavelength range (Laser Lenses, Windows, Prisms, Mirrors, etc.). It is practically free of bubbles and inclusions. </p><br> <p class="JGS1"> <strong>JGS2: : </strong> Equivalent to Homosil 1,2 & 3 (Heraeus), Dynasil 1000 & 4000 and 5000 & 6000 (Dynasil)<br> JGS2 provides good UV and visible transmission.It is close in physical and chemical properties to JGS1. Available in thin & small sheet pieces, JGS2 is virtually bubble-free. Elements built from large pieces will most likely contain bubbles, so application should not be sensitive to these inclusions. Ideal Applications for JGS2: Condenser optics not concerned with scatter or distortion, high temperature and pressure applications, optical flats, microscope slides and sight glasses. </p><br> <p class="JGS1"> <strong>JGS1 : </strong> ENDquivalent to Suprasil 300 (Heraeus).<br> JGS3 is transparent in the ultraviolet, visible and infrared spectral regions, without considerable absorption bands in the 185-250 nm spectral region. It has no absorption bands in the visible physical properies with outstanding optical characteristics in the deep UV and the IR wavelength range. It is those requiring very wide wavelength range from DUV to MIR. It is quite a bit more expensive than Silicon and slightly less expensive than Calcium Fluoride or ZnS Multi-spectral grade. </p> </div> </div> <!-- Right Content 8 Cols --> </div> <hr> <div
