The LA4647-C is a Plano Convex-Lens with a diameter of 0.5 inches and a focal length of 20 mm, designed for use in the ARC 1050-1700nm range. This lens is sourced from Thorlabs, a leading vendor in the optical industry, and is available for purchase on their website.
The lens is made of UVFS material with the Mal-1965 ID, and it features a spherical shape. The geometry of the lens includes a 12.7 mm diameter, with a thickness of 1.8 mm at the edge and 4.3 mm at the center. The effective focal length (EFL) is 20.1 mm, and the back focal length (BFL) is 17.1 mm. The inner and outer radii are both 0 mm.
The LA4647-C is coated on both the front and back with the THo C Bbar coating, which is designed to enhance its performance in the specified wavelength range. This lens is a great choice for applications that require a high-quality, reliable optical component with specific properties.
