SLB-50.8B-200NIR2 50.8 mm Dia. x -199.5 mm FL; Coated; Double-Concave Lens 750-1550nm
The SLB-50.8B-200NIR2 is a high-quality double-concave lens, boasting a diameter of 50.8 mm and a focal length of -199.5 mm. This lens is sourced from OptoSigma, a renowned vendor known for their precision optical elements.
The lens is made from n-bk7 schott, a material widely used in optical systems due to its excellent optical properties. The base shape of the lens is circular, making it suitable for a wide range of applications.
The geometry of the lens is characterized by its diameter, thickness edge (6.1 mm), and thickness center (3 mm). The front and back surfaces of the lens are coated with opt ir2, a coating specifically designed for the 750-1550nm wavelength range. This coating enhances the lens' performance in the infrared spectrum, making it ideal for applications in this range.
The lens' spherical shape and double-concave design contribute to its high optical power. The inner and outer radii are 0, indicating a symmetrical design. The effective focal length (EFL) is -200.5 mm, and the back focal length (BFL) is -199.5 mm.
The lens is currently in stock and can be purchased directly from the vendor's website. The provided weblink leads directly to the product page for convenient access.
