G052403400 12.7 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-50mm
This is a G052403400 12.7 mm Dia. N-BK7 Mounted Double-Concave Lens, with a focal length (EFL) of -50mm, sourced from Qioptiq Photonics. The lens is mounted, indicating it is ready for immediate use in optical systems, and is made of N-BK7, a popular borosilicate glass known for its excellent optical properties.
The lens has a diameter of 12.7mm and a center thickness of 1.5mm. The double-concave design, with radii of curvature of -52.33mm for the first surface and 52.33mm for the second, contributes to its negative focal length. The lens has no inner or outer radius, indicating it is a simple, symmetric lens.
The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces, which enhances its performance in specific wavelength ranges. The coating is designed to reduce reflection and increase transmission, making the lens suitable for use in various applications.
This lens is a spherical lens, meaning it has a spherical surface. Spherical lenses are the simplest type of lens and are widely used in various applications due to their simplicity and versatility.
The lens is designed for use at a wavelength of 588nm. This makes it suitable for applications that use light at this wavelength, such as certain types of lasers or light-emitting diodes (LEDs).
