Description

Optical lens light transmission effect demonstration instrument

Technical Field

The utility model relates to a heater technical field particularly, relates to an optical lens printing opacity effect demonstration appearance.

Background

For cameras, the quality of a lens is always a key factor influencing the imaging quality, and digital cameras are no exception. Although the CCD resolution of a digital camera is limited, the optical resolution of the lens is in principle less demanding; on the other hand, the imaging area of the digital camera is small (because the digital camera is imaged on the CCD, and the area of the CCD is much smaller than that of the film of the conventional 35 mm camera), so that a lens is required to ensure a certain imaging quality. For example, for a certain subject, the horizontal direction requires 200 pixels to reproduce its details perfectly, if the imaging width is 10mm, a lens with an optical resolution of 20 lines/mm is sufficient, and if the imaging width is 1mm, the optical resolution of the lens must be more than 200 lines/mm. On the other hand, the traditional film is sensitive to ultraviolet rays, a UV mirror is often required to be additionally arranged for external photographing, the CCD is sensitive to infrared rays, and the imaging quality can be greatly improved by adding a special coating or an external filter to the lens. The physical aperture of the lens must be considered, and regardless of the relative aperture, the larger the physical aperture, the larger the luminous flux, the better the digital camera can receive and control the light, and the better the imaging quality. Some manufacturers of lenses for commercial or household digital cameras use relatively good lenses. The Fuji camera adopts a professional Fuji lens with 170 line/millimeter resolution, and the built-in novel Fuji lens is clearer than most SLR lenses. Not only the quality of image shooting is ensured in precision, but also the lens error rate reaches 0.3 percent which is surprising and is 2/3 percent lower than that of a common digital camera. In addition, in some digital cameras, two lens modes of long-distance and wide-angle are provided. This is also a reference index when you select a digital camera.

However, the light transmittance of a general optical lens is not good, which results in poor photographing effect.

An effective solution to the problems in the related art has not been proposed yet.
