Laser Raman Spectrometer
(PMT Based)
Model: HO-ED-S-06
Price : $ 12,500.00

Laser Raman Spectrometer (Model no: HO-ED-S-06) is primarily meant for post graduate courses in Physics and Engineering. It can be used as a laboratory analyzing tool as well.


Monochromator

The monochromator is of Czerny-Turner design with 50 mm x 50mm size plane grating having 1200 lines per millimeter. A sine drive mechanism with classic design is employed for rotation of grating by using a stepper motor. Enhanced aluminium coated concave mirrors are used for collimating the signal light. The monochromator chamber is sealed air tight. No user adjustments required for normal use.


Detector

PMT is used as detector. It is kept near to exit slit in an enclosure. The high voltage power supply required for PMT is made integrated with the detector housing.


Control Electronics and Software

Electronics hardware is made integrated for monochromator, detector and laser source so that fully automatic operation is possible from an interfaced computer. The software developed is dedicated for Laser Raman spectrometer with all standard capabilities. Holmarc’s engineers entertain customization of this software on request.


Sample Illumination and signal collection

Sample is illuminated by a laser. Though the instrument is supplied with 532 nm DPSS laser, it can be replaced by any laser of user's choice to suit application requirements. Laser mount and illumination chamber is made compatible for this purpose. Laser is guided to the sample by mirrors mounted on kinematic mounts. Sample can be either liquid or solid. Sample chamber is designed in such a way that liquid in a test tube or solid held on pin can be mounted for illumination. We customize the sample chamber at no extra cost as well. For efficient collection of signals, concave mirror and lenses are incorporated in the sample chamber.
