SLB-25B-150PIR2 25.0 mm Dia. x 150.5 mm FL; Coated; Double-Convex Lens 750-1550nm

The SLB-25B-150PIR2 is a 25.0 mm diameter, double-convex lens with a focal length of 150.5 mm, specifically designed for use in the infrared spectrum of 750-1550nm. This lens is sourced from OptoSigma, a renowned vendor known for their high-quality optical components.

The lens is made from n-bk7 schott, a popular material in the optical industry 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 3 mm and an edge thickness of 2 mm. The effective focal length (EFL) is 150.5 mm, and the back focal length (BFL) is 149.5 mm. The radii of curvature for the first and second surfaces are 155.7 mm and -155.7 mm, respectively.

The SLB-25B-150PIR2 is coated with Opt IR2, a broadband antireflection coating that is specifically designed for the infrared spectrum. This coating is applied to both the front and back surfaces of the lens, reducing surface reflections and improving transmission in the specified wavelength range.

This lens is a great choice for applications that require high-quality, broadband infrared transmission, such as thermal imaging, spectroscopy, and other infrared-based technologies. With its robust design and high-performance coating, the SLB-25B-150PIR2 is a reliable and versatile optical component.
