OPT-26 DENSE FLINT GLASS PRISM FOR SPECTROMETER

This is an equilateral prism with all the 3 angles of 600 each and all the sides measuring 25mm each.

It is made of optically worked dense flint glass which has a relatively high refractive index of approximately 1.65 and a high dispersion.

The flint glass prisms are mainly used with spectrometers.

Students can also understand how chromatic aberrations can be reduced by combining a flint glass prism with a crown glass prism. The dispersions of the glasses partially compensate for each other.
