Equilateral Prisms
Equilateral
prisms are most commonly used as dispersing elements.
When used at minimum deviation, they produce the highest dispersion.
This makes them useful in spectroscopy where a source of light may be
broken into its constituent wavelengths for analysis.
These prisms may be made from different glass types in order to change
the amount of dispersion.
We
offer equilateral prisms made of the following glass types:
The
accuracy of these prisms is controlled by the precision of the prism angles. The standard level of accuracy has an angular deviation of 3
arc minutes.
We
offer equilateral prisms uncoated
but special coatings can be applied on request.
We
can supply equilateral prisms in the following standard sizes: 20, 25, 30, 40,
50, 60 mm.
