The Characteristics and Applications of Zinc Selenide Lens CharacteristicsSmall focused spot with wipe resistance, small power loss with strong photo permeability. As the most economic transmission focus element, lens are suitable for heat treatment with a la...

Round Concave Mirriors Round concave mirrors are catoptric imaging. Mirrors( including convex) are reflecting back for imaging rather than get through the light, ray of light follows the law of reflection, that is what we c...

How to Judge whether Achromatic Doublet Lens is Good or not? Achromatic doublet lens is a kind of glass that can change the direction of light transmission and the relative spectrum of ultraviolet, visible or infrared light. In the narrow sense, achromatic bi-...

Quality Standard of Achromatic Lens The difference between achromatic lens and other glasses is that as a part of optical system, it must meet the requirements of optical imaging. Therefore, the determination of the quality of achromati...

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...

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 ...

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...

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 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 ...

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...

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 ...

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...

Why Use Penta Prism for SLR Cameras? People nowadays are very familiar with SLR cameras. SLR cameras are single-lens reflex viewfinder digital cameras. The principle of SLR cameras is to use a single lens to view the view, and the light ...

Production Process of Cylindrical Lens The production process of cylindrical lens mainly includes rough grinding, fine grinding, polishing, centering and edging.1. Rough grinding of cylindrical lensGenerally, the rough grinding of a small ...
