VSpec is a high performance software that provides sophisticated spectroscopy capabilities for professional researchers, including full control of popular spectrometers and detectors, and exceptional support for displaying and managing spectral data. Added to this is all the capability of the Digital Optics high-performance imaging architecture.



Standard and Professional Versions


VSpec is a powerful dedicated spectroscopy package with extensive hardware support, based on the V++ system architecture. VSpec Pro combines the full set of V++ imaging features with the spectroscopy features of VSpec, making a sophisticated package for the researcher who wants everything. Both versions are equipped with the powerful VPascal language for automating your experiments, including functions for automated spectrometer and camera control.



Spectrum Display


VSpec allows you to display and process as many spectra as you wish using its versatile spectrum display windows. Spectra may consist of one or more strips, and may have multiple frames so you can process a time-series of spectral measurements. Every spectrum window has its own calibration settings.



Spectral Corrections


Corrections such as reference subtraction, flat field, software accumulation, derivative, absorbance, and transmission can be applied during live data collection or post processing.



Spectroscopy and Imaging Functions


VSpec and VSpec Pro incorporate many functions for processing both spectral and image data. Please see the V++ pages for details about the many hundreds of available functions.



Spectrometer Control


VSpec includes a sophisticated architecture for controlling spectrometers, cameras, and other detectors. You can access all hardware features (and even control multiple instruments simultaneously) but the interface always remains easy to understand and use.















Many popular spectrometers are supported, for example DeltaNu and Acton monochromators and imaging spectrographs, including control of filter wheels, shutters, diverter mirrors, and motorized slits. Please contact us regarding support for other spectrometer brands.


Single Point Detectors, such as Acton PMTs, are fully supported, with features such as strip chart display, chopper control, and the ability to control multiple detectors simultaneously.





Extensive calibration functionality is provided, with both manual and automatic modes. Manual wavelength calibration includes automatic peak finding for fixed position spectrograph / camera systems or scanning monochromator / PMT spectral acquisition systems. Automatic calibration uses the spectrograph specifications and grating dispersion equation (adapted for a spectrograph to calculate wavelengths for adjustable spectrometer or CCD systems). Both methods allow calibration of input and output in wavelength (nm, micron, Angstroms) and energy (wavenumber, relative wavenumber and electron volts).



Camera Support


All VSpec versions include complete support for a wide variety of scientific CCD cameras, including products from Intevac, Princeton Insturments and Photometrics. Features include live focus, single & multiple strips/region exposures, multiple camera control, and sequence acquisition.
