Borosilicate Windows

  • Introduction

 Borosilicate Windows are ideal for high temperature and harsh environment applications. With its excellent shock and thermal resistance property, borosilicate window products can maintain flatness in different environmental conditions.


types of Borosilicate Windows


Unlike common borosilicate that is drawn flat, is produced by a float technique that yields superior surface flatness — typically 4 - 6λ per inch.  For more information per material property, please refer to Schott official  brochure.


Borosilicate Windows


Hyperion Optics orders directly from Schott, offer two grades of custom borosilicate or equivalent windows, float grade which are cut from standard float sheet material and polished grade which are further intensively polished for better flatness and surface quality according to application requirement. We have been providing our standard and custom optical window for filter, first surface mirrors, protection windows utility.
