LB4842-B UV Fused Silica Bi-Convex Lens; Dia:2 in; f=200.0 mm ARC 650-1050nm

The LB4842-B is a high-quality bi-convex lens made from UV fused silica, a material renowned for its excellent transmission properties and resistance to thermal shock. This lens, with a diameter of 2 inches and a focal length of 200.0 mm, is designed for use in the ARC 650-1050nm range, making it suitable for a wide range of applications in the visible and near-infrared spectrum.

The lens features a double-sided broadband anti-reflection coating, specifically THo BBAR, which significantly reduces surface reflections and increases transmission. The front and back surfaces of the lens are coated, ensuring optimal performance from all angles.

The geometry of the lens includes a thickness of 3 mm at the edge and 6.5 mm at the center, providing excellent structural integrity. The radii of curvature for the first and second surfaces are 183 mm and -183 mm, respectively, resulting in a back focal length of 197.7 mm. The lens is spherical in shape, ensuring a high degree of optical accuracy.

This lens is sourced from Thorlabs, a leading vendor in the field of optical components, ensuring a high level of quality and reliability. The current status of the item is 'in stock', indicating its availability for immediate purchase and delivery.
