LD5313-E 25.4 mm Dia. CaF2 Double-Concave Lens; EFL=-50mm 3-5µm
The LD5313-E is a high-quality double-concave lens, boasting a 25.4 mm diameter and a center thickness of 3 mm. This lens is designed for use with a wavelength of 588 nm and features an effective focal length (EFL) of -50 mm, making it ideal for applications that require a strong converging or diverging lens.
The lens is made from Calcium Fluoride (CaF2), a material known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. This makes the LD5313-E a versatile choice for a wide range of optical applications.
The lens features a double-concave geometry, with radii of curvature of -43.8 mm and 43.8 mm for the front and back surfaces, respectively. This geometry is designed to provide a high degree of optical power while minimizing spherical aberration.
The LD5313-E is coated with Thorlabs' ECaF2ARC20005000 coating on both the front and back surfaces. This coating is designed to enhance the lens's transmission in the ultraviolet, visible, and near-infrared regions, and to provide protection against environmental contaminants.
This lens is sourced from Thorlabs, a leading vendor in the field of optical components. According to the vendor, the lens is currently in stock, ensuring quick delivery times.
