A BLUE-Wave spectrometer can be coupled with a F600 optical fiber and an IS6 integrating sphere to be calibrated for Watt flux/nm laser measurement
Spectrometers for Laser Measurement
These miniature rugged spectrometers are calibrated to measure and track laser frequency and centroid wavelength and/or total power of lasers in Watts. Currently, StellarNet offers laser measurement systems in the 200-2300nm range. All of StellarNet’s spectrometers can be configured for laser measurement including the BLUE-Wave, GREEN-Wave, High Resolution, and High Resolution NIR spectrometer models. The spectrometers can additionally be calibrated with our NIST traceable lamps for absolute intensity to be used to capture laser intensity profiles and shape. Typically an integrating sphere such as the IC2 2″ or IS6 6″ integrating sphere is coupled along with a radiant flux calibration (RAD-CAL).

Visible Laser Measurement Spectrometers
The StellarNet miniature spectrometers are fiber optically coupled instruments with a wide selection of models for laser measurements in 200-1150nm wavelength ranges
Visible High Resolution (HR) 
Systems
The HR spectrometers have double the resolution over standard models with the same grating. The wavelength range is reduced by the same factor. Resolutions better than 0.1nm can be achieved depending on selected model range, detector, and slit size.
NIR High Resolution Systems
In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which uses high resolution NIR spectrometers. WDM is based on the concept of using multiple wavelengths of light on a single fiber by using different wavelengths (colors) of laser light to carry different signals. Conventional WDM systems provide channels in the C-band of silica fibers around 1550 nm. StellarNet uses tunable laser sources for calibration of the high resolution unit. The NIR3-HR InGaAs 1024 is recommended to cover the 1500-1640nm range and provides FWHM of 0.7nm

NIST Calibrations 
The factory performs calibrations for the appropriate wavelength range of your spectrometer using NIST traceable calibration lamps (calibration service such as IRRAD-CAL must be ordered with spectrometer and proper measurement accessories) Fast delivery: most system can be calibrated and shipped within 1 week after receipt of order. Absolute calibration: accuracy within 10% at detector integration setting used for calibration. Certificate available: documentation with NIST traceable serial numbers. If the user has an appropriate irradiance calibration source lamp, a field re-calibration can be easily performed using the included SpectraWiz software. Calibrations are available for UV, VIS,NIR ranges and can be configured for spectral irradiance (W/m^2), radiance (W/m^2/sr) and total power in watt flux in Watts.

The factory performs several x-axis calibrations on all spectrometers and depending on customer application a StellarNet spectrometer may be calibrated also in the y-axis for absolute intensity measurements. A y-axis Irradiance calibration is performed using NIST traceable lamps. There are several available calibrations depending on your spectrometer wavelength range and slit size.
