SLB-10B-40PIR2 10.0 mm Dia. x 40.4 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-10B-40PIR2 is a high-quality lens offered by OptoSigma, designed for use in the 750-1550nm wavelength range. This lens is a Spherical Lens (Convex-Convex) type, featuring a base shape of a circle.
The lens has a diameter of 10.0 mm and a thickness at the edge of 2.0 mm. The thickness at the center is slightly more, measuring 2.6 mm. The Effective Focal Length (EFL) of this lens is 40.4 mm, making it suitable for a variety of optical applications.
The curvature of the lens is defined by two radii: the first radius (R1) is 41.52 mm, while the second radius (R2) is -41.52 mm, indicating a double-convex lens. The Back Focal Length (BFL) is 39.6 mm. The lens is made of n-bk7 schott material, a common choice for its excellent optical properties.
The lens features a coating on both the front and back surfaces. The coating is Opt IR2, which is specifically designed for use in the infrared spectrum, enhancing the lens' performance in its intended wavelength range.
