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...
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...
Technology and Application of MWIR Lens
1. The use of MWIR lensWith the development of infrared detector technology and application requirements, the use of MWIR lenses is also increasing. Due to the refrigerating mechanism used by the medi...
On-chip Arbitrary Mode Spot Conversion
On-chip photonic devices show great potential in many applications, including communications, microwave photonic signal processing, quantum information, sensing and computing. Recently, researchers ha...
Manufacturing of Optical Prisms
1. Realize dispersion through optical prismsAn outstanding feature of optical prisms is that they can be imitated as a flat mirror system to simulate light reflection in the prism medium. Replacing mi...
