SLB-50.8B-60PIR2 50.8 mm Dia. x 62.3 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-50.8B-60PIR2 is a high-quality lens from OptoSigma, designed with a 50.8 mm diameter and a focal length of 62.3 mm. This lens is made from the renowned material n-bk7 schott, which is known for its excellent optical properties.
The lens features a double-convex geometry, with radii of curvature of 62.28 mm for both the front and back surfaces. This shape allows for a broad range of applications, particularly in systems where a high level of focusing is required. The lens has a center thickness of 13.8 mm and an edge thickness of 3 mm, providing robustness and durability.
The SLB-50.8B-60PIR2 is coated with Opt IR2 on both the front and back surfaces. This coating enhances the lens' performance in the infrared spectrum, specifically between 750nm and 1550nm. It ensures high transmission rates and reduces unwanted reflections, making it ideal for applications such as thermal imaging, spectroscopy, and other infrared-based technologies.
