SLB-06B-20PIR2 6.0 mm Dia. x 20.2 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-06B-20PIR2 is a spherical lens with a base shape of a circle, designed and manufactured by OptoSigma. This lens is specifically designed for use within the wavelength range of 750-1550nm, making it suitable for a variety of applications within this spectrum.
The lens has a diameter of 6.0 mm and a thickness at the edge of 1.0 mm. The thickness at the center of the lens is 1.4 mm, providing a robust structure for optical applications. The effective focal length (EFL) of this lens is 20.2 mm, which is a critical parameter in lens selection.
The lens features a double-convex geometry, with radii of curvature of 20.76 mm for the first surface and -20.76 mm for the second surface. The back focal length (BFL) is 19.8 mm. The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range.
The lens is coated with Opt IR2 on both the front and back surfaces. This coating enhances the lens's performance within the infrared spectrum, providing improved transmission and reduced reflection.
