SLB-30-70PIR2 30.0 mm Dia. x 70.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-30-70PIR2 is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 30.0 mm and a focal length of 70.0 mm. 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 constructed from n-bk7 schott, a popular material in optical applications due to its excellent optical properties and versatility. The Plano-Convex geometry, with a center thickness of 5.2 mm and an edge thickness of 2 mm, ensures a long focal length and a wide field of view. The lens has an effective focal length (EFL) of 70.0 mm and a back focal length (BFL) of 66.5 mm.
The lens features a coating of opt ir2 on both the front and back surfaces. This coating enhances the lens' performance within its specified wavelength range, improving transmission and reducing reflection. The coating also provides protection for the lens surface, increasing its durability and lifespan.
