Glaslinse & optische Linse

glass lens&optical lens Superior performance to singlet lenses Nearly constant focal length across the visible spectrum.Far superior off-axis performance.Multi-layer or single-layer AR coatings.Standard diameters and focal lengths interchange with our singlet lensesOur achromats are computer designed to effectively minimize spherical aberration and coma when operating at infinite conjugate ratio, yielding smaller focused spot sizes. Unlike singlet lenses, this results in a constant focal length independent of aperture and far better off-axis performance. Achromats are superior to singlet lenses for monochromatic applications at any visible wavelength
