Spectograph diffraction filter
WebJul 17, 2024 · Designing a spectrometer is a nonlinear process. It starts linearly: (1) State the measurement problem. (2) Determine the wavelength range, photometric precision, and resolution desired. (3) Estimate available size, power, and financial resources. (4) Devise optical parameters that meet the constraints of (1)– (3). WebStructure of a Spectrograph; Recording a Spectrum; Dispersing Light. Light entering a spectrograph can be split or dispersed into a spectrum by one of two means, using a prism or a diffraction grating. When Newton split light …
