Application of Optical Glass in Optics

Application of Optical Glass in Optics

Glass that can change the propagation direction of light and the relative spectral distribution of ultraviolet, visible or infrared light is called optical glass. Optical glass is an inorganic glassy material that transmits light through refraction, reflection, transmission or changes the intensity or spectral distribution of light through absorption.

Is concave lens the same as divergent lens

Is concave lens the same as divergent lens

A concave lens is not necessarily a divergent lens. The rays that enter the divergent lens parallel to its axis diverge, and all rays seem to originate from its focus F. But the dotted line is not light, but indicates the direction of light. The focal length f of the diverging lens is negative.

What are the characteristics of aspherical lens that spherical lens does not have

Aspheric lenses are used to eliminate spherical aberration in a variety of applications, including barcode scanning, laser diode collimation, or OEM or R&D integration. The aspherical lens uses a single element design, which helps minimize the number of lenses in a multi lens optical fitting.
