SLB-20-30PIR2 20.0 mm Dia. x 30.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-20-30PIR2 is a Plano-Convex Spherical Lens, sourced from OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 20.0 mm and a focal length of 30.0 mm, is designed for use within the wavelength range of 750-1550nm, making it suitable for a variety of applications in the infrared spectrum.
The lens is made from n-bk7 schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. The Plano-Convex geometry, with a center thickness of 5.6 mm and an edge thickness of 2 mm, ensures a wide field of view and low distortion. The lens has an effective focal length (EFL) of 30.0 mm and a back focal length (BFL) of 26.3 mm.
The SLB-20-30PIR2 is coated with Opt IR2, a broadband anti-reflection coating that enhances its performance in the infrared spectrum. This coating reduces surface reflections, improving light transmission and image quality. The coating is applied to both the front and back surfaces of the lens.
