The SLB-50-200NIR2 is a Plano-Concave Spherical Lens, designed with a circular base shape and a diameter of 50.0 mm. This lens is sourced from OptoSigma, a renowned vendor known for its high-quality optical elements. The lens is made from n-bk7 schott material, a popular choice for its excellent optical properties.
The lens features a thickness edge of 6.1 mm and a thickness center of 3 mm, providing a robust structure. It has an effective focal length (EFL) of -200.0 mm, making it suitable for a wide range of optical applications. The first radius of curvature (R1) is -103.8 mm, and the back focal length (BFL) is -202 mm, contributing to its unique optical characteristics.
The SLB-50-200NIR2 is coated with opt ir2 on both the front and back surfaces, enhancing its performance in the 750-1550nm wavelength range. This coating ensures optimal transmission and reduces reflection, making it ideal for use in infrared applications.
