Abstract
A prism spectrometer having higher resolution and wider spectral width through the use of a speckle generating diffuser.
Claims4
A spectrometer comprising:
- a first cylindrical lens adapted to receive light from a light source;
- a diffuser film adapted to diffuse light received from said first cylindrical lens so as to create a spectrally varying spatial pattern;
- an optical slit that limits a scattering of the light diffused from said diffuser film;
- a second cylindrical lens that collimates light received through said optical slit, said diffuser film positioned between said first cylindrical lens and said second cylindrical lens;
- and
- a prism that separates wavelengths of light received from said second cylindrical lens on a horizontal axis.
