G063058329 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-20mm 1064nm
This is a G063058329 model lens, a high-quality optical component manufactured by Qioptiq Photonics. It is a spherical lens with a base shape of a circle, designed with a negative focal length (EFL) of -20mm, specifically for the wavelength of 588nm. The lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties.
The lens has a diameter of 22.4mm and a center thickness of 1.5mm. The first radius of curvature (R1) is -20.833mm, and the second radius of curvature (R2) is 20.833mm, indicating a double-concave lens design. The inner and outer radii are both zero, suggesting a symmetrical lens structure.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces, providing anti-reflection properties that enhance its performance in specific applications. This coating is particularly effective for the YAG laser wavelength of 1064nm, as indicated in the item name.
The item data also indicates that this lens is in stock and available for purchase, with direct links to the vendor's website provided for convenience. This lens is a great choice for applications that require a high-quality, double-concave lens with specific optical properties.
