SLB-07B-12PIR2 7.0 mm Dia. x 12.5 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-07B-12PIR2 is a 7.0 mm diameter, double-convex lens with a focal length of 12.5 mm, sourced from the reputable vendor OptoSigma. This lens is designed for use within the wavelength range of 750-1550nm, making it suitable for a variety of applications within the infrared spectrum.
The lens is crafted from the high-quality material n-BK7 Schott, a borosilicate glass known for its excellent optical properties, including low dispersion and high transmission across a wide range of wavelengths. The lens features a double-convex geometry, with radii of curvature of 12.46mm for the first surface and -12.46mm for the second surface, facilitating efficient light collection and focusing.
The lens has an edge thickness of 1.8mm and a center thickness of 2.8mm, providing robustness and durability. The effective focal length (EFL) is 12.5mm, and the back focal length (BFL) is 11.5mm, allowing for precise placement within optical systems.
The SLB-07B-12PIR2 is equipped with an IR2 coating on both the front and back surfaces. This coating enhances the lens's performance within the infrared spectrum, reducing reflection and increasing transmission. The coating status is currently in stock, ensuring prompt availability for your optical needs.
