SLB-50B-100NIR2 50.0 mm Dia. x -99.5 mm FL; Coated; Double-Concave Lens 750-1550nm
The SLB-50B-100NIR2 is a high-quality double-concave lens, designed and manufactured by OptoSigma. This lens, with a diameter of 50.0 mm and a focal length of -99.5 mm, is specifically designed for use in the infrared spectrum, between 750nm and 1550nm.
The lens is made from n-bk7 schott, a popular material in optical systems due to its excellent optical properties. The base shape of the lens is circular, and it features a spherical geometry with a center thickness of 3mm and an edge thickness of 9.1mm. The inner and outer radii are both 0mm, and the back focal length is -100.5mm.
The SLB-50B-100NIR2 is coated with Opt IR2 on both the front and back surfaces, enhancing its performance in the infrared spectrum. This coating helps to reduce reflection and increase transmission, making it ideal for use in applications such as thermal imaging, spectroscopy, and other infrared-based technologies.
The lens is currently in stock and available for immediate purchase. For more information, including detailed specifications and purchasing options, please visit the vendor's website using the provided weblink.
