Astronomical Spectroscope


In this highly-dispersive instrument, light from the slit passes through the upper part of six tall equilateral prisms, through a totally reflecting prism, and then back through the lower part of the six prisms and into the viewing scope. Howard Grubb, an optical instrument designer from Ireland, introduced the form in 1870.
