Prism Vs Grating | Difference between Prism and Grating

This page compares Prism Vs Grating and mentions difference between Prism and Grating.

Prism	Grating

It is made of Quartz, Calcite or Glass.	It is made of aluminium or material with bright surface (about 2500 to 60000 lines per inch).
It can work between 400 to 1000 nm regions.	It can work between 200 to 800 nm regions.
It's spectrum is not as pure as grating.	It's spectrum is much more pure as compare to prism.
10 to 25 nm of ray band can be acquired.	5 nm ray band can be acquired.
Dispersion of light is not sharp.	Dispertion of light is very sharp.
Ability of dispertion of light can not be extended.	Ability of dispersion of light can be extended by increasing lines per inch.
No ghost spectrum is acquired.	Ghost spectrum is acquired when lines are not proper on grating.
