Terms related to Optical Filters1) Central wavelength (CWL): The wavelength used, such as the main peak of the light source is 850 nm led lamp, requires a central wavelength of 850 nm.2) Transmittance (T): Assuming that the initial ...view
What are the Uses of Optical Filters?Optical filters are a relatively unfamiliar concept for many people. They seem to be a little far from our daily life, but they are not. Looking closely at the surroundings, we will find that many asp...view
Differentiation between Doublet Lens and Ordinary LensDoublet lenses are the most commonly used optical materials with mature manufacturing technology and complete varieties. Generally, doublet lenses can transmit colored light with wavelengths ranging f...view
Manufacturing Method of Doublet Lens Curing TechnologyMore than 30 years ago, ultraviolet (UV) light was successfully applied in commercial applications. Various adhesives manufacturers have developed a series of UV products for bonding, sealing, printin...view
The Use and Storage of Doublet LensDoublet lenses are consumable. Aging begins immediately after opening the seal. During the long-term use, the surface of the doublet lens will continue to increase defects and stains. These defects or...view
How to Design and Manufacture Aspherical Lens?Aspheric fabrication is different from traditional spherical fabrication. In traditional spherical manufacturing, the surface is defined by a single radius of curvature. Curvature can be ground and po...view
Advantages and Disadvantages of Aspherical LensesThe surface radian of aspherical lens is different from that of ordinary spherical lens. In order to pursue the thinness of the lens, it needs to change the surface of the lens. Aspheric lens should b...view
Different Advantages of Each Aspheric Lens TypeSince the lens performance required for all applications is different, it is very important to choose an appropriate aspheric lens. Key factors to consider include your project schedule, overall perfo...view
