SLB-30B-170PM 30.0 mm Dia. x 170.5 mm FL; Coated; Double-Convex Lens 400-700nm
The SLB-30B-170PM is a high-quality lens from OptoSigma, designed for use in the 400-700nm wavelength range. This lens is a spherical, biconvex design, made from n-bk7 schott material, which is known for its excellent optical properties.
The lens has a diameter of 30.0 mm and a focal length of 170.5 mm, making it suitable for a wide range of optical applications. The edge thickness of the lens is 2.0 mm, while the center thickness is 3.3 mm, providing a robust and durable structure. The effective focal length (EFL) of the lens is 170.5 mm, and the back focal length (BFL) is 169.5 mm.
The SLB-30B-170PM lens features a coating on both the front and back surfaces, which is indicated as 'opt m' in the item data. This coating enhances the lens' performance by reducing reflection and increasing transmission, thereby improving the overall efficiency and quality of the optical system.
The lens is designed for use in the visible spectrum, with a central wavelength of 546.1 nm. The base shape of the lens is circular, and the geometry is spherical, which is a common and versatile design for many optical applications.
