Espectroscopía fotónica aplicada: medida y análisis espectral económico

More and more incandescent lights are being replaced by LEDs each day. LEDs have the advantages of increased efficiency, color specificity, size, response time, lifetime, and numerous other factors. StellarNet's line of low cost miniatureradiometers are the perfect tool to analyze LEDs for both irradiant output, color, spectral profiling, and a handful of other useful values. These instruments are NIST calibrated to measure the absolute intensity over the wavelength range in nanometers provided by the selected fiberoptic compact spectrometer model. Currently, StellarNet offers LED Radiometer systems in the 200-1700nm range; the table at the bottom of the page outlines various ranges for each StellarNet Spectroradiometer. The StellarNet BLUE and GREEN-Wave, BLACK-Comet concave grating model, and the RED-Wave-NIR InGaAs model can all be configured for perfect LED measurement. For a complete LED measurement system, in addition to a StellarNet Spectrometer, a fiber optic cable and an integration sphere are needed for both accurate and precise measurement.

Extended Range Spectroradiometers
StellarNet also has extended range spectroradiometers available to measure spectral irradiance over a wide range of wavelengths. The EPP2000-UVN-SR spectroradiometer with CCD detector array covers a range of 200-1100nm. While the BLACK-Comet-SR super range dual blazed concave grating spectroradiometer offers a range of 200-1080nm or 220-1100nm while retaining all of the characteristics of a concave grating spectrometer. In addition, StellarNet offers a Dual Channel Spectrometer system for spectroradiometry, the Dual DSR (Detector Super Range) combines a CCD and InGaAs detector to cover a wavelength range of 200-1700nm for selected models.

Dual DSR Spectroradiometer
StellarNet Dual DSR system uses a Y bifurcated fiber (F600-Y-UVSRNIR) to connect a BLACK-Comet-SR spectrometer and a RED-Wave NIR Spectrometer. The entire system can be radiometrically calibrated over the range 200-1700nm. Above system pictured with Flash Capture Interface (FCI) that allows spectrometer to capture emission from flashing sources such as flashtubes and pulsed solar simulators.

NIST 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
• 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

StellarNet Integrating Spheres allow collection of light with an 180 field of view. The IC2 is a 2" internal diameter sphere with 2 SMA connectors for illumination and collection of LED light. The input port is 5/8". The IS6 and IS12 are 6" and 12" StellarNet integrating spheres with 2.5" input port with internal white coating. Mounting tripods and other accessories are available for LED measurement.
