BICX505 50 mm Dia. x 400 mm FL; Uncoated; Double-Convex Lens

The BICX505 is a high-precision, double-convex lens offered by WTS Photonics, boasting a diameter of 50 mm and a focal length of 400 mm. This lens is designed for use in a variety of applications, thanks to its robust construction and high-quality materials.

The lens is spherical in shape, with a base shape of a circle. It features a double-convex design, meaning it has two convex surfaces. This design is often used to collimate or focus light, making it ideal for applications such as imaging, beam shaping, and laser systems.

The geometry of the lens is carefully crafted to ensure optimal performance. The edge thickness measures 3 mm, while the center thickness is 4.5 mm. The effective focal length (EFL) is 400 mm, and the back focal length (BFL) is 398.5 mm. The radii of the curvature of the two surfaces are 413.87 mm and -413.87 mm, respectively.

The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This makes the lens suitable for use across a wide range of wavelengths, with a specified wavelength of 546.1 nm.

Notably, the lens is uncoated. While coatings can be used to enhance the performance of lenses in certain applications, an uncoated lens can be advantageous in situations where cost, simplicity, or specific optical characteristics are priorities.

The lens is currently in stock and available for immediate purchase through the WTS Photonics website, as indicated by the "Valid - in stock" status in the item data.
