OPTICAL COMPONENTS Spherical Lenses Cylindrical Lenses Lens Kits Achromatic Doublets Multi-Element Micro Optics Mirrors Prisms Fused Silica Windows Broad transmission spectrum Օ Thermal stability Scratch rթsistant Round, square and rectangular sizes available When the broadest transmission spectrum is required (from 185nm to over 2 microns) together with high durability, all for a reasonable cost, these windows are ideal. Fused silica is physically Substrates & Windows Beamsplitters Polarizers Filter & Apertures robust and resists chipping and scratches. The coefficient of thermal expansion is quite low, so these windows maybe subjected to higher levels of thermal shock than glass or sapphire can withstand.
