SLB-30-35NIR2 30.0 mm Dia. x -35.0 mm FL; Coated; Plano-Concave Lens 750-1550nm
The SLB-30-35NIR2 is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 30.0 mm and a focal length of -35.0 mm. This lens is designed for use within the wavelength range of 750-1550nm, making it suitable for near-infrared applications.
The lens is made from n-bk7 schott, a popular material in optical systems due to its excellent optical properties and high Abbe number. The lens's geometry includes an inner radius of 0 mm and an outer radius of 0 mm, with a thickness at the edge of 9.9 mm and a center thickness of 2 mm. The back focal length (bfl) is -36.3 mm, and the effective focal length (efl) is -35 mm.
The SLB-30-35NIR2 is coated with Opt IR2 on both the front and back surfaces. This coating enhances the lens's performance within its specified wavelength range, providing improved transmission and reduced reflection. The coating status is currently in stock, as indicated by the weblink status.
