G314335331 12.7 mm Dia. N-BK7 Plano-Concave Lens; EFL=-500mm
This is a Plano-Concave lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a diameter of 12.7 mm and a center thickness of 1.5 mm. The effective focal length (EFL) of this lens is -500mm, indicating that it is a diverging lens, causing incoming light rays to spread out.
The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. The inner and outer radii of the lens are 0, indicating a plano-concave shape, where one side is flat, and the other side is curved inward.
The lens is coated with Qio AR RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating reduces unwanted reflections and increases transmission, enhancing the performance of the lens in its intended application.
The lens is designed to operate at a wavelength of 588 nm. This makes it suitable for applications that use light at this wavelength, such as certain types of lasers or light-emitting diodes (LEDs).
