With over 20 years of experience, StellarNet designs instrumentation that meets the rigid quality standards for the most challenging testing requirements.
StellarNet Calibration Facility
The StellarNet calibration facility has a variety of NIST traceable ultra-stable light sources, including UV Deuterium & VIS-NIR Tungsten Halogen covering 200-2500nm range. StellarNet utilizes lamps for absolute calibration of spectral irradiance, precision radiant and luminous flux output, white-light standards for spectral radiance and luminance, and has numerous filtering/aperture assembly options for high/low light applications and custom calibration configurations.
Spectrometer Calibrations
The factory performs calibrations for the appropriate wavelength range of your spectrometer using NIST traceable calibration lamps (calibration service 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.
Pick your favorite spectrometer or even use multi-channels as in our dual system BLUE-Wave-UVN (200-1050nm) and DWARF-Star (900-1700) which can be calibrated over the entire region providing seamless data
- Absolute calibration: accuracy within 10% at detector integration setting used for calibration.
- Certificate available: documentation with NIST traceable serial numbers.
StellarNet offers a variety of spectrometers available to measure over a wide range of wavelengths. Visit the StellarNet spectrometers page to pick your model. StellarNet NIST traceable calibrations can be performed from 200-1700nm.
If the user has an appropriate irradiance calibration source lamp, a field re-calibration can be easily performed using the included SpectraWiz software.
Annual calibration and calibration packages available. Please contact your StellarNet Sales representative for more information. Contactus@StellarNet.us
Experimental Setup for Laser, Laser Diode, and LED characterization. Larger Spheres such as IS6 and IS12 can be used in place of low cost IC2.
