SLB-40B-170PIR2 40.0 mm Dia. x 170.7 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-40B-170PIR2 is a 40.0 mm diameter, double-convex lens with a focal length of 170.7 mm, specifically designed for use in the 750-1550nm wavelength range. This lens is sourced from OptoSigma, a renowned vendor known for their high-quality optical elements.
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, with a thickness of 2 mm at the edge and 4.3 mm at the center. The effective focal length (EFL) is 170.7 mm, while the back focal length (BFL) is 169.3 mm. The radii of curvature for the first and second surfaces are 176.46 mm and -176.46 mm respectively.
The SLB-40B-170PIR2 features a coating of opt ir2 on both the front and back surfaces. This coating enhances the lens' performance in the infrared spectrum, making it ideal for applications such as thermal imaging, spectroscopy, and other infrared-based technologies.
