Cold Processing Procedure of Optical Lens
The first way: milling, is to remove the uneven surface of optical lens bubbles and impurities, (about 0.05-0.08) play a forming role.The second process is to eliminate the damage layer of the milling...
Aspherical Lens are Lighter, Thinner, Flatter
The spherical lens is with a constant curvature from the center of the lens to the edge, while the aspherical lens changes continuously from the center to the edge. In photographic lenses, many aberra...
The Introduction of Bandpass Filter
A bandpass filter is a filter that can pass the frequency component within a certain frequency range but attenuate the frequency component of the other range to a very low level. An example of analog ...
The Use of Filter in the Counterfeit Detector
The currency detector is an optoelectronic instrument for checking the authenticity of banknotes, involving many fields such as machinery, electricity, light, and magnetism. The counterfeit identifica...
The Advantage Application of Fresnel Lens in LED Projection Lamp
Usually, the Fresnel lens is cut into a spherical surface shape in order to minimize the optical aberration of the image during imaging. The lens can better align an ideal point light source into a pa...
What Kind of Lens is the Best Choice for the Projector Lens
