G314317000 22.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-150mm Uncoated
This is a Plano-Concave lens, type N-BK7, from the renowned optical components manufacturer, Qioptiq Photonics. The lens, model G314317000, has a diameter of 22.4 mm and a center thickness of 1.5 mm. The effective focal length (EFL) of this lens is -150mm, making it a negative or diverging lens.
The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. This particular lens is uncoated, meaning it does not have any additional layers to enhance its optical performance or protect it from environmental factors.
The lens's geometry is spherical, with a radius of curvature (R1) of -78.298 mm for the concave surface. The inner and outer radii are both zero, indicating that this lens does not have any additional shaping or features on its edges.
This lens is designed to operate at a wavelength of 588 nm. It is important to note that the performance of the lens can vary depending on the wavelength of the light it is intended to focus or transmit.
