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...
The Forming Process of Aspheric Lens
1. Precision glass moldingPrecision glass molding is to heat the glass material to a high temperature to become plastic, shaping it through an aspheric mold, and then gradually cool it to room tempera...
The Functions of a Fisheye Camera Lens
1. Introduction to fisheye camera lensFisheye lens is an extreme wide-angle lens, and "fisheye camera lens" is its common name. In order to maximize the photographic angle of view, the front...
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...
Different Types of Filters
Small and tiny though a filter is, it plays a vital role. As a part of the optical industry, filters play a key role. So what kinds of filters are there according to the spectral characteristics?1. Lo...
Classification of Optical Lenses and Their Functions
Optical glass refers to glass that can change the direction of light propagation and can change the relative spectral distribution of ultraviolet, visible or infrared light. Optical lenses are made of...
SWIR Lens
1. Introduction of SWIR lensesLight is a kind of electromagnetic wave, with the visible spectral of 0.38-0.76um, and the infrared spectral region of 0.76-1000um.The part of 0.76-3.0um is called refle...
Types and Applications of Optical Prisms
1. What are optical prisms?In optical devices, optical prisms can cut a piece of glass or other transparent materials at a precise angle and plane, which can be used to analyze and reflect light. Ordi...
What Is a Beam Expander?
1. Brief introduction of beam expanderA light or laser beam expander is a scientific instrument that can expand the input beam of parallel light or laser into a larger output beam. In terms of usage, ...
The Application of Zoom Lenses
Ⅰ. The selection principle of the zoom lensesThe maximum imaging circle size of the lens should not be less than the imaging specification of the camera chip, that is to say, 1/2 lens can be used wit...
Achromatic Lenses
1. The introduction of achromatic lensAchromatic lenses have various configurations, the most common of which are positive achromatic lenses, negative achromatic lenses, three-phase achromatic lenses ...
Pentagonal Prism/Half Pentagonal Prism Estimate
The pentaprism deviates the lights beam by 90° through reflection of two surfaces while maintaining image parity. The deviation of the beam will not change the slight rotation of the prism, so it is ...
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...
