G313205000 22.4 mm Dia. N-BK7 Double-Concave Lens; EFL=-20mm Uncoated
The G313205000 is a high-quality double-concave lens from Qioptiq Photonics, featuring a 22.4 mm diameter and a center thickness of 1.5 mm. This lens is designed for use with a wavelength of 588 nm and is made from the renowned N-BK7 glass from Schott, ensuring excellent optical performance.
The lens's geometry is characterized by its symmetric concave shape, with both radii of curvature measuring -20.833 mm. This design results in a negative effective focal length (EFL) of -20 mm, making it suitable for a wide range of applications that require image inversion or reduction.
Notably, this lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements. However, it's essential to consider that uncoated lenses may have higher reflectivity, which could impact the overall system performance.
