G052404400 12.7 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-100mm
This is a G052404400 12.7 mm Dia. N-BK7 Mounted Double-Concave Lens, with a focal length (EFL) of -100mm, sourced from Qioptiq Photonics. The lens is designed for use in precision optics applications and features a symmetrical concave-concave geometry, making it suitable for a wide range of optical systems.
The lens has a diameter of 12.7 mm and a center thickness of 1.5 mm, providing a compact and robust design. The double-concave shape, defined by radii of -104.41mm and 104.41mm, ensures excellent light-gathering capabilities and a wide field of view. The lens is made from N-BK7 Schott glass, a popular material known for its high homogeneity, low auto-fluorescence, and excellent transmission properties in the visible spectrum.
The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces, enhancing its overall light transmission and durability. This coating provides high reflectivity and excellent environmental stability, making the lens suitable for use in various environments and applications.
The item data also indicates a wavelength of 588nm, suggesting that this lens is optimized for use in the yellow-orange region of the visible spectrum. This makes it an excellent choice for applications such as fluorescence microscopy, spectroscopy, and other optical systems where precise control of light is required.
