WebOptical spectrometers (often simply called "spectrometers"), in particular, show the intensity of light as a function of wavelength or of frequency. The different wavelengths of light are separated by refraction in a prism or by diffraction by a diffraction grating. Ultraviolet–visible spectroscopy is an example. WebAs the grating in a spectrometer is rotated about an axis parallel to the slit axis, the spectral lines are transmitted successively through the instrument.

WebJan 20, 2024 · The two main types of dispersive elements are prisms and diffraction gratings; diffraction gratings are more commonly used in modern spectrophotometers. WebSounds like the setup has the correct order. I think what you need to consider is that the light spreads after the grating and the whole spectrum should fit the lens, otherwise you'll miss part of it. No interference should be present in the readings. Additionally, if the incoming light is not collimated, you might need a curved mirror or lens.
