G313330329 22.4 mm Dia. UVFS Double-Concave Lens; EFL=-20mm 1064nm
This is a G313330329 double-concave lens, featuring a diameter of 22.4 mm and a center thickness of 1.5 mm. The lens is designed with a focal length of -20 mm, making it suitable for applications that require a concave lens. The lens is made of UVFS (mal- 1965), a material known for its excellent optical properties.
The lens is coated with Qio HP Nbar Arhs-Yag on both the front and back surfaces, providing enhanced durability and performance. This coating is particularly useful in applications involving high-power lasers, as it helps to reduce unwanted reflections and increase transmission.
The lens's geometry is characterized by its two radii of curvature, R1 and R2, which are -20.535 mm and 20.535 mm, respectively. These radii give the lens its double-concave shape, which is often used to focus or diverge light beams. The lens's inner and outer radii are both zero, indicating that the lens has a uniform thickness.
This lens is designed for use with a wavelength of 355 nm. It is available from Qioptiq Photonics, a leading vendor in the field of precision optics. According to the vendor's website, the lens is currently in stock, making it readily available for immediate use.
