Monochromator - Wikipedia

A monochromator can use either the phenomenon of optical dispersion in a prism, or that of diffraction using a diffraction grating, to spatially separate the colors of light. It usually has a mechanism for directing the selected color to an exit slit. Usually the grating or the prism is used in a reflective mode.

The groove spacing and blaze angle determine the distribution of energy. In Littrow use, light is diffracted from the grating back toward the source. Gratings used in the Littrow configuration have the advantage of maximum efficiency (or blaze) at specific wavelengths.

to quickly collect grating efficiency in the selected diffracted order. Design considerations The spectral test station for measuring plane diffraction grating efficiency and po- larized response has many advantages, not the least of which is the sytem's simplicity and reliability3. It measures in conditions that approximate those of actual use.

The used analyzer grating had a period of μm and gold structures of 100 μm height. The intergrating distance was set to cm, that is, the third fractional Talbot distance. The relative grating position is set to . For the detector, we assumed the use of a single‐photon‐counting detector with an effective pixel size of 8 μm.

Light and Spectra INTRODUCTION Light and color have intrigued humans since antiquity. In this experiment, you will consider several aspects of light including: a. The visible spectrum of colors (red to violet) b. Bright line spectra as emitted by an excited gas or solid c. The relationship between color, wavelength, fre‑ quency and energy.

Spectrometer - Wikipedia

Spectrometer - Wikipedia

A spectrometer (/ s p ɛ k ˈ t r ɒ m ɪ t ər /) is a scientific instrument used to separate and measure spectral components of a physical phenomenon. Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed.
