HEM Grown Optical Sapphire |
|||||||||||||||||||||
HTOT’s HEM grown sapphire provides superior optical qualities. It has low transmission wavefront distortion, a broad transmission range from the ultra violet (UV) to the infrared (IR) spectrum with thermal stability and high strength. HTOT’s sapphire is grown using the automated HEM sapphire growth process. This time proven crystal growth method allows for the growth of sapphire in large sizes with superior crystalline structure and low inclusion levels that provides high optical performance in a wide range of optical window applications. Applications include aerospace, Astronomical and high power lasers. HEM Sapphire CharacteristicsHEM grown sapphire is a preferred material for optical applications that require stability, abrasion resistance, strength and light transmission over a wide range. (150nm to 5000nm) • High mechanical strength Sizes
HEM Sapphire ApplicationsThere is an increasing demand in technical industries for large sapphire windows. Airplanes and UAVs, (Unmanned Aerial Vehicles), have advanced reconnaissance systems and other large view ports that sapphire is perfectly suited for. These advanced systems have many different light sources and detectors working at different wave lengths. Sapphire windows are capable of hosting these various equipment sets, working at different wavelengths under its one protective and efficient optical material. HEM sapphire has no thickness restrictions so windows can be utilized in pressurized and unpressurized situations. Sapphire is also increasingly viewed as a window material upgrade from Zinc Sulfide (ZnS) and Magnesium Fluoride (MgF2) for airborne applications. It is well known that sapphire is commercially available unlike other optical materials such as Alon and Spinel which are more expensive with weaker performance compared to HEM sapphire. GT Crystal Systems is committed to supporting its customers as they develop new technical solutions using HEM Sapphire. This document is copyright © September 1, 2015 GHTOT. All rights reserved.
