This is a Plano-Convex lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a base shape of a circle and a diameter of 25.4 mm. The thickness at the edge of the lens is 2 mm, while the thickness at the center is 4 mm. The effective focal length (EFL) of this lens is 80 mm, making it suitable for a variety of optical applications.
The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. The inner radius of the lens is 0 mm, and the outer radius is also 0 mm, indicating that this is a plano-convex lens, where one side is flat and the other side is curved.
The lens is designed to work within the wavelength range of 588 nm. It comes with a coating on both the front and back surfaces. The coating is Qio Bbar Arb2nirnbk7, which is a type of anti-reflective coating that reduces light loss due to reflection.
