Raman / PL Spectroscopy
Holmarc manufactures and supplies a confocal laser Raman spectrometer as a fully assembled and ready-to-use instrument for material characterization and identification in industry as well as research labs.
Holmarc's Confocal Laser Raman Spectrometer combines an upright microscope with high N.A objective with a computer interfaced spectrometer. The microscope performs sample irradiation and signal collection. A laser beam focused by the microscope objective irradiates a small spot in the sample. The same objective collects scattered light from the sample and collimates for microscope optics and focusing at the input slit of the spectrometer. The Rayleigh line is rejected with the help of a high-OD edge filter, and Raman light is only fed into the spectrometer. The spectrometer is a Czerny-turner type with 1200 l/mm grating and line CCD detector. The exposure of the CCD and laser intensity can be adjusted to get impressive Raman signals.
Holmarc supplies this Raman instrument along with a vibration isolated table as a standard accessory. Depending upon the application requirements, we undertake customization of the spectrometer grating, detector, and software interface.
