Double Gaussian Lens

        Double gaussian lens group is the most commonly used photographic camera lens, with the focal length of the imaging range is between 35-100mm, can provide 20 ° - 50 °half Angle, in system design,the symmetric form lens mainly used centre optical cable , the lens group with negative lens in the center around the central aperture and outboard usually put meniscus lens. According to the different halves Angle or aperture, such as design system can contain 5-8 surface of optical lenses.
