Optical Glass Bk7 Dome Sapphire Dome for CCTV PTZ Camera and Underwater Camera

Product Description
Optical Lenses are optical components designed to focus or diverge light, widely applicated from microscopy to laser processing. A Plano-Convex or Double-Convex lens causes light to focus to a point, while a Plano-Concave or Double-Concave lens diverges the light which traveling through the lens. Achromatic Lenses are ideal for correcting color, aspheric lenses are designed to correct spherical aberration.Ge, Si, or ZnSe lenses are suited for transmitting the Infrared (IR) spectrum, fused silica is well suited for the Ultraviolet (UV). 


Glass Domes
Glass Domes are ideal for commercial applications requiring a protective boundary between two environments. Performing as windows, these N-BK7 glass domes allow you to easily protect electronic sensors or detectors without sacrificing field of view. Our glass domes are hemispheric in shape making them easy to mount directly to any surface.
