Description
HOLMARC’s Spectra Quasar Series Monochromators Model : HOSP-SQR500FA & HO-SP-SQR300FA are fully automated, triple grating instruments with dual output port while Models HO-SPSQR500F & HO-SP-SQR300F are single grating instruments with single output port. All the four models are designed for fast, automated and continuous scanning over broad spectral range. The angular position of the grating is adjusted by the use of sine drive mechanism so that only the required wavelength of light is passed through the exit slit and all other wavelengths are blocked, without changing the positions of mirrors and slits.
Spectra Quasar series monochromators are ideal choice for either single or multichannel detector to be used in many applications that require medium to high spectroscopic resolution with excellent stray light performance such as fluorescence, Raman, absorption and transmission. Spectra series monochromators are fully automated with microprocessor controls and can be interfaced with the device by using RS 232C serial port.
Input and output ports of the monochromator are fitted with precise, micrometer controlled variable slits. The software developed for the instrument has facilities for setting up and calibration as well. System accepts input data as wavelength or wave number. Various configurations of input and output ports are available with precision and long life time.
Precision stepper motor controlled rotation stage is used for driving the grating. Fine resolution for the grating stage is achieved by microstepping feature of the stepper motor drives. Wavelength selection is made much easier in automated system compared to manually adjusted versions.
