G314301329 22.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-40mm 1064nm
This is a Plano-Concave Lens from Qioptiq Photonics, a leading provider of precision optics. The lens has a diameter of 22.4 mm and a center thickness of 1.5 mm. The effective focal length (EFL) of this lens is -40mm, making it a negative or diverging lens. The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and high damage threshold.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission at the YAG laser wavelength of 1064nm, making it suitable for high-power laser applications. The lens is spherical in shape, with a radius of curvature of -20.833 mm on the concave surface. The inner and outer radii are both 0, indicating a uniform curvature.
The lens is unmounted, meaning it does not come with any housing or mounting hardware. It is available for purchase from the Qioptiq shop, where it is currently in stock. The weblink provided leads directly to the product page for easy access and purchasing.
