SLB-50.8-700PIR2 50.8 mm Dia. x 700.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-50.8-700PIR2 is a Plano-Convex Spherical Lens with a diameter of 50.8 mm and a focal length of 700.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.
The lens's geometry includes a 3.0 mm edge thickness and a 3.9 mm center thickness, contributing to its robustness and durability. The inner and outer radii are both 0, indicating a straightforward design. The lens's effective focal length (EFL) is 700.0 mm, and the back focal length (BFL) is 697.4 mm, providing a clear focus and optimal performance.
The SLB-50.8-700PIR2 is coated with Opt IR2 on both the front and back surfaces, enhancing its performance in the 750-1550nm wavelength range. This coating reduces reflection and increases transmission, making it ideal for applications such as IR imaging, spectroscopy, and beam shaping.
