SLB-15B-70PIR1 15.0 mm Dia. x 70.5 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-15B-70PIR1 is a high-quality lens from OptoSigma, designed for use in the 633-1064nm wavelength range. This lens is a Spherical Lens (Convex-Convex) type, featuring a base shape of Circular for versatile application.
The lens has a diameter of 15.0 mm, with a thickness edge of 2.0 mm and a thickness center of 2.8 mm, providing a robust structure for various optical setups. The effective focal length (EFL) of this lens is 70.5 mm, making it suitable for medium to long-range optical systems.
The curvature of the lens is defined by its first and second radii, R1 and R2, which are 72.66 mm and -72.66 mm respectively. These values indicate a double-convex lens, which is often used to collimate or focus light. The back focal length (BFL) of this lens is 69.5 mm, which is a critical factor when designing an optical system.
The lens is made from n-bk7 schott, a popular material for optical lenses due to its excellent optical properties. It is coated with opt ir1 on both the front and back, enhancing its performance in the specified wavelength range.
