Surface accuracy is the measurement of the deviation between the actual shape and the intended shape of an optical surface. Surface accuracy is an important specification of an optical component.
We left off in the interference post using water waves to represent the interference that occurs between light waves. A well known experiment having to do with interference of light
An objective lens is an important component of a microscopy or imaging system for a range of science research, biological, industrial, and general lab applications. An objective lens is located
Shanghai Optics is continuously monitoring the latest news about the COVID-19 situation. That’s why we are doing all we can to make sure all our locations are 100% operational
Besides explaining rainbows, why model light as a wave? The particle model of light is usually drawn with a particle traveling as a ray. Just by staring at a candle
Electromagnetic spectrum covers many wavelength regions from Gamma ray, X ray, ultraviolet (UV), visible light, infrared (IR) to radio wave. Visible light is the portion of the electromagnetic spectrum that
In “What is Light?”, we described light as both a wave and a particle under the conditions of the wave-particle duality. In the previous posts, we have mostly modeled light
Besides lenses and mirrors, prisms are another group of common optical elements. White light that enters a prism leaves as many different colors due to the different refractive indexes of
In the previous post, we looked at how changing the focal lengths produced different images (and virtual images) for SINGLE lenses. Sometimes, however, a system of lenses is needed to
