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...
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...
Selection Basis for Aspheric Lens
The aspheric lens has a better radius of curvature and can maintain good aberration correction to obtain the required performance. The application of aspheric lenses brings excellent sharpness and hig...
What Makes Achromatic Lenses Important
Because achromatic lenses focus colors at the same point, they allow users to fully focus the image. Compared with uncorrected singlet lenses, achromatic lenses can produce clearer images, making it e...
What Makes Apochromatic Lenses Important?
Because apochromatic lenses focus colors at the same point, they allow users to fully focalize the image. Compared with uncorrected singlet lenses, apochromatic lenses can produce clearer images, maki...
