SLB-50.8B-100NM 50.8 mm Dia. x -99.5 mm FL; Coated; Double-Concave Lens 400-700nm
OptoSigma's SLB-50.8B-100NM is a spherical lens with a base shape of a circle, designed for use in the 400-700nm wavelength range. This lens is a double-concave type, featuring two concave surfaces. The lens has a diameter of 50.8mm and a center thickness of 3mm, while the edge thickness is 9.3mm. The effective focal length (EFL) of this lens is -99.5mm, and the back focal length (BFL) is -100.5mm.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The front and back surfaces of the lens are coated with opt m, a broadband anti-reflection coating that enhances transmission and reduces surface reflections.
This lens is a great choice for applications that require a broad spectrum of light to be focused or collimated, such as in imaging systems, beam shaping, or spectroscopy. The double-concave design allows for a wide range of focal lengths, making it a versatile component in many optical systems.
