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 -30mm, making it a negative or diverging lens. This means that it spreads out light rays, causing them to diverge from a single point.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The wavelength for this lens is 588nm, which falls within the visible light spectrum.
The lens is coated with qio bbar arb2visnbk7 on both the front and back surfaces. This coating is designed to reduce reflection and improve transmission, making it ideal for use in high-precision optical systems.
The lens is unmounted, meaning it does not come with any housing or mounting hardware. This allows for flexibility in integration into various optical systems.
