G314322329 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-100mm 1064nm

This is a Plano-Concave lens with a diameter of 25.4 mm, sourced from the renowned optical components manufacturer, Qioptiq Photonics. The lens is made of N-BK7, a popular glass type known for its excellent optical properties, particularly its low dispersion.

The lens features a concave shape with a center thickness of 1.5 mm and an effective focal length (EFL) of -100 mm at a wavelength of 1064 nm. The concave shape, also known as negative meniscus, is characterized by a negative radius of curvature (R1: -51.212 mm). This shape is often used in optical systems to diverge or spread out light.

The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission, particularly at the YAG laser wavelength of 1064 nm.

The lens is spherical in shape, meaning it has a constant curvature throughout its surface. This shape is the simplest and most common type of lens, making it a versatile choice for various optical applications.

The lens is currently in stock and available for purchase on the Qioptiq Photonics website. For more information, please refer to the provided weblink.
