G314316331 22.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-100mm
This is a Plano-Concave lens with a diameter of 22.4 mm, manufactured by Qioptiq Photonics. The lens is made of N-BK7, a popular optical glass type known for its excellent optical properties. The lens's design features a concave shape on one side and a flat surface on the other, making it suitable for applications that require beam divergence or collimation.
The effective focal length (EFL) of this lens is -100mm, which means it will cause incoming light to spread out, or diverge. This makes it ideal for use in laser applications where a broad, divergent beam is required. The lens has a center thickness of 1.5 mm, providing sufficient structural integrity while maintaining a low profile.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating reduces unwanted reflections and increases transmission, ensuring optimal performance in your optical system.
