This is a Plano-Convex Lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a diameter of 6 mm and a center thickness of 3 mm, with an edge thickness of 0.68 mm. The effective focal length (EFL) of this lens is 6 mm, making it suitable for applications that require a short focal length.
The lens is made of N-BK7, a popular optical glass from Schott. This material is known for its excellent optical properties, making it a common choice for various optical applications. The lens is unmounted, providing flexibility for users to integrate it into their systems according to their specific requirements.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This coating is designed to enhance the lens' performance at a wavelength of 1064 nm, which is commonly used in laser applications. The coating reduces reflection and increases transmission, thereby improving the overall efficiency of the optical system.
