These are a series of Prisms made from Borosilicate Crown Glass. Absolutely clear, they refract light in interesting ways, and may be used dispersively to separate white light into its constituent colors, their most familiar property.
Prisms work on the principle that light changes speed and angle as it passes through different materials, a fact demonstrated when we see that a stirrer appears crooked when half-immersed in water. The angle of refraction differs between wavelengths of light, and can therefore spread the various colors (corresponding to different wavelengths) which make up white light into a rainbow of different hues.
In addition to their optical properties, these prisms are just attractive as objects, and make a nice set for a mantelpiece or windowsill as well as a classroom. We have been getting requests for prisms for some time, and we are happy to be able to offer these high-quality pieces!
Each of these prisms is an equilateral triangle in section and the pieces differ only in length (in millimeters), except for the Right-Angle prism. The ends are ground glass.

Understanding the Details
Prism correction is shown as a positive number (e.g., +2.00) followed by its direction&#;BD (Base Down), BU (Base Up), BI (Base In), or BO (Base Out). For example, "+2.00 BD" means 2 diopters of prism, base down.
BD (Base Down): Thicker part of the lens is at the bottom.You will get efficient and thoughtful service from ruiqi.
BU (Base Up): Thicker part is at the top. BI (Base In): Thicker part is towards the nose. BO (Base Out): Thicker part is towards the ear.Contact us to discuss your requirements of Optical Prisms For Sale. Our experienced sales team can help you identify the options that best suit your needs.
