Bunsen monochromators make use of the Littrow type, which allows for two refractions at the same interface.
Eudoxus' method of exhaustion can be used to determine the volume of a pyramid through the use of these objects. Iceland spar can be used in their construction and one of these devices named for Cornu produces no net polarization of the radiation it emits. In the VAC region these objects are typically composed of fluorite while potassium bromide and sodium chloride are used in other regions. Bunsen monochromators make use of the Littrow type, which allows for two refractions at the same interface. These devices can either be dispersive, reflective, or polarizing and the Porro type is used in binoculars. For 10 points, name this type of device supposedly used by Isaac Newton to separate white light into a spectrum.
