Spectrometer ESS3271 Lecture Spectrometer - An optical instrument used to measure properties of light over a specific portion of the electromagnetic spectrum - The variable measured is most often the light's intensity - A spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities Light dispersion Mirror Detector Slit + Filter Grating Diffraction Grating - An optical ponent with a surface covered by a regular pattern of parallel lines, typically with a distance between the lines parable to the wavelength of light - Light rays that pass through such a surface are bent as a result of diffraction, related to the wave properties of light - This diffraction angle depends on the wavelength of the light Grating Equation k: diffraction order and n: groove density (g/mm) Littrow Condition Photomultiplier Tube (PMT) - Extremely sensitive detectors of light in the ultraviolet, visible and near infrared - Multiply the signal produced by incident light by as much as 108, from which single photons can be resolved - Photomultipliers are constructed from a glass vacuum tube which houses a photocathode, several dynodes, and an anode - Incident photons strike the photocathode with electrons being produced as a consequence of the photoelectric effect - These electrons are directed by the focusing electrode towards the electron multiplier, where electrons are multiplied by the process of secondary emission - Each dynode is held at a more positive voltage than the previous one Spectrometers STSSeries OEMMicrospectrometer Amazing Full-Spectrum Performance in a Tiny Footprint NFOER 2W011 The STS introduces a family of pact, low-cost spectrometers that’s ideal for embedding into OEM devices. At just 40 mm x 42 mm x 24 mm (1.6”x 1.7”x 0.9”), the STS provides full spectral analysis with low stray light (<0.2% SRPR @ 450 nm), high signal-to-noise ratio (>1500:1) and optical resolution (~1.5 nm FWHM) - remarkable...
