Terms related to Optical Filters
1) 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 ...
What is a Bandpass Optical Filter?
In a certain band, there is only a small band with high transmittance in the middle and a high reflectivity cut-off band on both sides of the band. This kind of optical filter is collectively called b...
Analysis of Optical Lens
From the word light alone, we can see that it means bright and transparent. Optical lenses must have these attributes and have good transparency.Optical lenses are highly transparent, chemically a...
New Applications of Optical Lens Bonding
Optical manufacturers usually use mercury lamp UV ovens when they glue lenses to lenses. Now most optical factories have realized the concept of environmental protection and energy saving, as well as ...
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 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...
How Much do You Know about the Projector Lens?
There are very few popular science on projector lenses. We often pay attention to chips, color wheels, heat dissipation, etc., but sometimes overlook the lenses that can be easily seen.Viewed from the...
Fresnel Lenses are Closely Related to Our Lives
At present, the main application fields of Fresnel lens include projection and solar photovoltaic field. Because the edge of the light penetrated through Fresnel lens is soft, it is often used in dyei...
What Kind of Lens is the Best Choice for the Projector Lens
Lenses of different materials will have different effects on the picture. According to the projector lens on the market at present, their lenses are mainly divided into two types, one is glass lens, t...
The Applications of Fresnel Lens
Fresnel lens is a branch of lens. Compared with other lenses, Fresnel lens has the advantages of small volume, light weight and compact structure. At the same time, it has good focusing property and i...
What Advantage does Sapphire Lens Have?
One type of part is indispensable in the composition of a watch, that is, the watch cover. After the renewal of the watch era, the watch cover has become wear-resistant and scratch-resistant, and the ...
