SLB-50.8-70NIR2 50.8 mm Dia. x -70.0 mm FL; Coated; Plano-Concave Lens 750-1550nm
The SLB-50.8-70NIR2 is a Plano-Concave Spherical Lens, 50.8 mm in diameter, with a focal length of -70.0 mm, specifically designed for use within the wavelength range of 750-1550nm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry.
The lens is made from n-bk7 schott, a high-quality optical glass, and features a Plano-Concave geometry. The lens's thickness at the edge is 13.4 mm, while the center thickness is 3 mm. The effective focal length (EFL) is -70 mm, and the back focal length (BFL) is -72 mm. The inner and outer radii are both 0 mm, indicating a flat surface on one side and a curved surface on the other.
The SLB-50.8-70NIR2 is coated with Opt IR2 on both the front and back surfaces, enhancing its performance within the specified wavelength range. This coating helps to reduce reflection and increase transmission, making it ideal for use in various applications such as beam shaping, collimation, and imaging.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
