The Ophir WaveStar introduces a new level of accuracy and ease in spectral measurements. Just plug into your PC parallel port, install the software and easily and accurately measure spectra from a wide variety of sources including continuous and pulsed sources from microwatts to watts in intensity. The WaveStar program automatically tags the peaks with the wavelength so the result is readily available. The WaveStar is available with interchangeable filters which together with the variable shutter speed allow you to easily and accurately measure any type of source from fractions of a microwatt to watts in intensity. Fiber adapters are available to connect to fiber sources. The WaveStar has up to four times higher resolution than similar competing instruments due to its innovative optical design (patent applied for). Its sophisticated peak interpolation algorithms allow you to find the peak wavelengths of lines at up to 10 times the accuracy of competing instruments and with greater ease. The built-in intensity calibration insures that the relative intensity vs. wavelength gives an accurate relative curve. This is especially important when measuring broadband sources such as lamps

Examples of Software Features

Intensity is corrected for variations in detector sensitivity so spectral curve intensity is proportionally correct	Zoom button blows up wavelength range selected with vertical bars below	Data log with time of peak wavelengths and FWHM	Continuously variable shutter speed from 28µs to 7.3s - a dynamic range of >100,000:1	Automatically tags all peaks with the center wavelength to an accuracy of ±0.1nm. Will show FWHM as well if desired

Horizontal bar determines threshold for displaying peak wavelength and FWHM so as not to clutter screen with unwanted data		Vertical bars select wavelength region of interest for displaying wavelength and FWHM values and zooming with zoom button

Example of Expanded Wavelength Scale

The first screen shows the spectrum of a pulsed diode laser where the user has selected the region to zoom with the mouse. The second screen shows the zoomed picture from the selected region.

The screen below shows the zoomed region selected in the first screen. Note the resolution of the spectrometer, where the laser longitudinal modes spaced at 1nm intervals are clearly shown. In this view, the FWHM as well as the wavelength is displayed above each peak.
