SLB-15B-70PIR2 15.0 mm Dia. x 70.5 mm FL; Coated; Double-Convex Lens 750-1550nm

The SLB-15B-70PIR2 is a high-quality lens from OptoSigma, designed for use in the 750-1550nm 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 and durable structure. The effective focal length (EFL) of this lens is 70.5 mm, making it suitable for a wide range of optical applications.

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 radii contribute to the lens's double-convex shape, which is designed to minimize spherical aberration and provide superior image quality.

The lens is made from n-bk7 schott material, a popular choice for its high refractive index and low dispersion. This material ensures excellent optical performance and durability.

The SLB-15B-70PIR2 comes with a front and back coating of opt ir2. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it ideal for use in high-precision optical systems.
