Biconcave Lens Synthetic Fused Silica 30mm Diameter −99.7mm Focal Length

SLSQ-30B-100N

These biconcave lenses are used when a very high negative power is required. They can be used in a multi-element system or alone to produce a diverging cone or virtual image. Sharpe edges, which are common in negative lenses, are removed by beveling to reduce the likelihood of chipping.

Details

◦There are two types of biconvex lenses available; synthetic fused silica for wavelengths less than 350nm ultraviolet light.
◦Consult our Sales Division for anti-reflection coatings suitable for your application.
◦Our lenses are listed by outside diameter and focal length to assist your selection according to required specifications.

Weight	0.0500kgs
Standard Coatings Available	Yes
Guide	Lenses are available in a large selection and in custom sizes and focal lengths. In addition to our standard coating we offer custom anti-reflective coating at specific wavelengths.
Remark	-
Attention	When a concave lens is used in combination with a convex lens it will be able to converge the light and can projected a suitable image. The biconvex spherical lens has chromatic aberration, and the focal length will vary depending on the wavelength. Please check the “wavelength characteristic of the focal length data” on “Technical Data” for the focal lengths of each wavelength. Transmissions losses due to reflection off the front and rear surfaces of the lens can be minimized by coating the surfaces. Consult our Sales Team for anti-reflection coatings suitable for your application. The outer edge of the concave side is chamfered and the result is possibility that the lens may have a smaller edge thickness for this design.
