Omni-λ180Di Omni-λ300Di and Omni-λ500Di

Double Monochromators/Spectrographs

The Double Monochromators/Spectrographs include two monochromators which are with fine alignment. Double Monochromator can operate as either an additive or subtractive dispersion mode. As the additive dispersion mode, the double monochromator/ spectrograph spectral resolution double boost, suitable for high resolution measurement. As the subtractive dispersion mode, the double monochromator/spectrograph stray light can be reduced effectively, suitable for weaker signal detection, such as Raman spectra measurement.

Omni-λ180Di double monochromator
 
Omni-λ180Di is a all-in-one subtractive dispersion mode double monochromator. With the design and optical path adjustment, only the dispersion light converge at the exit slit for output, effectively reducing stray light. Obtaining purer monochromatic light, Omni- λ180Di is used to meet the needs of week signal testing, such as Raman spectroscopy and photodetector spectral responsivity calibration.


Features
Subtractive dispersion mode double monochromator.
Outstanding stray light rejection, less 10-9
All-in-one design, convenient for transportation and installation.
USB 2.0 interface, controlled by software
UV-VIS-NIR wide spectral range

 
Application
Tunable light source: Integrated with broad band light source, Omni-λ180Di can output purer monochromatic light for more accurate test.
Raman spectra measurement: When collecting the Raman scatting light, Omni-λ180Di can be used as a narrow band filter to eliminate the excitation laser's effect efficiently for measuring the low shift Raman spectra.
Professional detector spectral responsivity calibration: Omni-λ180Di can reduce calibration errors, especially in ultraviolet wavelength.

 
Specification
Dispersion measured with 1200g/mm grating @ 435.8nm
Resolution measured with 1200g/mm @ 435.8nm, 10um slit width and 4mm slit height
