G063892400 25.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-50mm

This is a G063892400 model lens, a high-quality optical component manufactured by Qioptiq Photonics. The lens features a double-concave design with a base shape of a circle, making it suitable for a wide range of applications. The lens has a diameter of 25.4 mm and a center thickness of 1.5 mm, providing a substantial surface area for light transmission while maintaining a compact profile.

The effective focal length (EFL) of this lens is -50mm, indicating its concave nature. The first radius of curvature (R1) is -52.33mm, and the second radius of curvature (R2) is 52.33mm, suggesting a symmetrical design. The lens does not have any inner or outer radius, which is typical for mounted lenses.

The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold. It is designed to operate at a wavelength of 588nm. The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces, enhancing its light transmission capabilities and durability.

The lens's spherical shape ensures consistent optical performance across the entire surface, making it a reliable choice for various applications. The lens is currently in stock and can be purchased directly from the Qioptiq Photonics website using the provided weblink.
