22-712 150mm Dia. N-SF5 Precision Aspheric Lens; EFL=120mm; NA=0.63 BBAR 425-675nm
The 22-712 is a high-precision aspheric lens offered by Edmund Optics, boasting a 150mm diameter and a numerical aperture (NA) of 0.63. This lens is designed for use in the visible spectrum, specifically at a wavelength of 587.6nm.
The lens is made from N-SF5 Schott, a high-quality optical glass known for its excellent transmittance and low autofluorescence. The aspheric design of the lens helps to reduce spherical aberration, resulting in improved image quality and increased light gathering capability.
The lens features a effective focal length (EFL) of 120mm, making it suitable for a variety of imaging applications. The front and back surfaces of the lens are coated with BBAR 425-675nm coating, which enhances the transmission of light in the specified wavelength range and reduces surface reflections.
The lens has a center thickness of 45.4mm and an edge thickness of 7.3mm, providing structural rigidity and resistance to deformation. The front and back surfaces of the lens have a radius of curvature of 80.725mm and 0mm respectively, and the lens has a conic constant of -0.843.
