Prism Confocal Raman Spectrometer

Dual Excitation Laser, Full Motorized Automation

Stock Status: In Stock


Prism Confocal Microscope Raman System is a high performance, fully automated, highly integrated Raman spectrometer system designed by NOST Optical Instruments. In its optical system, due to the very few moving parts, Prism reduced the optical uncertainty to minimum, as well as the calibration efforts. All optical positioning and calibration has been set up before shipment, so that users & research can work immediately after open the package. Prism is deliverd along with the acquisition and analysis software, in which allows you to test the sampels with highly friendly and powerful software environment.

Traditional Raman spectrometers are typically equipped with Czemy-Turner spectrograph. The disadvantage of a Czemy-Turner is its aberration issue. In the spectrograph design of NOST's PRISM Confocal Raman Microscopy Raman spectrometer, the aberration issue is greatly improved. The aberration issue is greatfully reduced, and the throughput and resolution are significantly increased. In the low-light optical analysis of the Raman spectroscopy applications, PRISM brought to you the excellent optical performance. The below figure shows the obvious improvement in astigmatism, coma and spherical aberration(The RMS of the spot <10 μm on all pixels along the entire wavelength range).

Spectrograph Prism

Regarding to the other optical designs in Prism Confocal Microscope Raman spectrometer, such as interchangeable grating turret grating, motorized laser ND filter, optimized image contrast display, can greatly reduce aberrations, remove rayleigh scattering purify the beam, and increase SNR and OD.
