Prisms refract light to reflect (reflective prism), disperse (dispersive prism), or split (beam splitter) light.Prisms are usually made of glass, but any material can be used as long as the material is transparent and suitable to the designed wavelength. Common materials include glass, plastic and fluorite.
Prisms are designed with different surface angles depending on the application field. ILLUCO produces prisms with excellent surface precision and appearance quality based on 20 years' accumulated know-how and technology.
Canada balsam is a resin obtained from canadian balsam tree. It has transparent pale yellow color and strong viscosity. Due to its high optical quality and similar refractive index to crown, this is commonly used for making adhesives for lenses and slides of microscope.
In the prism, it is used as an adhesive to bond calcite cut diagonally at 68 degrees when making Nicole Prism, which is used to generate and analyze planar polarization.
