G063072331 22.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-100mm
This is the G063072331 model from Qioptiq Photonics, a 22.4 mm diameter N-BK7 mounted plano-concave lens with an effective focal length (EFL) of -100mm. The lens is made of N-BK7 Schott glass, a popular choice for its high homogeneity and excellent transmittance in the visible and near-infrared spectral regions.
The lens's geometry is characterized by a center thickness of 1.5mm and a radius of curvature (R1) of -52.33mm. The plano-concave shape, where one surface is flat and the other is curved, is ideal for applications that require light to be focused or dispersed over a wide area. The lens's inner and outer radii are both zero, indicating a sharp transition between the lens's surfaces.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating reduces surface reflections and increases the lens's transmittance, making it suitable for use in high-precision optical systems.
The lens's wavelength is 588nm, which falls within the visible light spectrum. This makes it suitable for use in applications that involve visible light, such as imaging systems, beam shaping, and laser applications.
