SLB-10B-30NIR2 10.0 mm Dia. x -29.7 mm FL; Coated; Double-Concave Lens 750-1550nm

The SLB-10B-30NIR2 is a high-quality double-concave lens, designed and manufactured by OptoSigma. This lens, with a diameter of 10.0 mm, is specifically engineered for use within the wavelength range of 750-1550nm, making it ideal for near-infrared applications.

The lens features a base shape of a circle, with a center thickness of 2.0 mm and an edge thickness of 2.8 mm. The effective focal length (EFL) is -29.7 mm, indicating its double-concave nature. The first radius of curvature (R1) is -31.14 mm, while the second radius (R2) is 31.14 mm, further emphasizing its concave-concave geometry. The back focal length (BFL) is -30.3 mm.

The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This lens is coated with Opt IR2, a broadband anti-reflection coating that enhances its performance in the near-infrared spectrum.
