Plano Concave Lens Synthetic Fused Silica 30mm Diameter −170mm Focal Length

SLSQ-30-170N

These simple negative lenses have many uses. Alone they form a virtual image of a distant object or collimated light source. Used in combination with other optics they reduce the power of the system. Sharp edges which are common in negative lenses are removed by beveling in order to reduce the likelihood of chipping.
◦There are three types of plano concave lenses available; synthetic fused silica for wavelengths less than 350nm ultraviolet light, and synthetic fused silica lens for excimer laser wavelengths such as KrF (248nm) and ArF (193nm).
◦Our lenses are listed by outside diameter and focal length to assist your selection according to required specifications.
