I. What is a Dove Prism A Dove prism, also known as a Dove Prism, is a type of reflecting prism that looks like a right-angle prism with its apex removed and is commonly used to invert images. When light enters one of its oblique faces, it undergoes total internal reflection at the longest bottom…

A lens is an optical component made of transparent material with a surface that is part of a spherical surface. Lenses are composed of several lens pieces, including plastic lenses and glass lenses, with glass lenses being more expensive than plastic ones. Common lens constructions used in cameras include 1P, 2P, 1G1P, 1G2P, 2G2P, 4G,…

I. What are Filters? Filters are optical devices used to select specific radiation bands. One commonality among filters is that none of them can make astronomical imaging brighter because all filters absorb certain wavelengths, making objects appear darker. II. Two Major Types of Filters There are various types of filters in machine vision used to…

I. Introduction to Prisms A prism is a transparent object formed by intersecting pairs of non-parallel planes, used to deviate the path of light beams or cause dispersion of light. Prisms are typically polyhedrons made of transparent materials and are crucial optical components in optical instruments. The applications of prisms are extensive and can be…

Ⅰ Differences Between Optical Glass and Ordinary Glass Optical glass refers to glass that can change the direction of light propagation and alter the relative spectral distribution of ultraviolet, visible, or infrared light. Narrowly defined, optical glass refers to colorless optical glass; broadly defined, it also includes colored optical glass, laser glass, quartz optical glass,…

As an ancient material, glass is used in architecture and the arts and is frequently employed in medicine, instrumentation, and other fields. Different types of glass exhibit distinct characteristics that must be considered when using them. However, many people lack sufficient understanding of glass, leading to misunderstandings and complications. In this article, we will analyze…
