G314301000 22.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-40mm Uncoated
The G314301000 is a Plano-Concave lens with a diameter of 22.4 mm, sourced from Qioptiq Photonics. This lens is made of N-BK7, a popular glass type in the optical industry known for its excellent optical properties. The lens's concave shape, with an inner radius of 0 and an outer radius of 0, results in a negative focal length of -40 mm (EFL).
The lens's geometry is defined by its diameter and thickness at the center. The diameter is 22.4 mm, and the center thickness is 1.5 mm. Despite its thin profile, this lens is designed to bend light effectively due to its concave shape.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, uncoated lenses can be advantageous in certain applications where specific coatings might interfere with the desired optical effects.
The lens is designed to work with a wavelength of 588 nm, making it suitable for applications that use this wavelength, such as specific types of laser systems or monochromatic lighting applications.
