Light sources
Ocean Optics
Sources for illumination cover various ranges to enable absorbance, reflectance, and fluorescence measurements from deep-UV to NIR. Compact Light-emitting diodes produce output for fluorescence measurements.
- Deuterium light sources: Used most often for UV absorbance and reflectance measurements.
- Combination Deuterium and Tungsten light sources: Used as a single illumination sources for measurements across broad wavelength ranges.
- Pulsed Xenon Lamps: Used as long life sources for absorbance, reflectance and fluorescence measurements, and for measuring optically or thermally labile samples.
- Tungsten Halogen light sources: Used most often as standard VIS-NIR light sources for absorbance, reflectance of solid objects, and color measurements.
- Light emitting diode: Used as excitation sources for fluorescence. Feature minimal warm-up and high stability. Power is lower and spectral width is wider than with lasers.
Radiometric Calibration Sources
Ocean Optics
Radiometric Calibration Standard: VIS-NIR: Each of these radiometric sources comes with a regulated 12VDC power supply. Also included certificate and a diskette with data files foe use with our irradiance software.
Calibrated with Fiber & Cosine diffuser is designed for calibrating the absolute spectral response of a complete system consisting of a spectrometer and an optical fibrer and/ or a cosine corrector.
Calibrated for use with intergrating sphere:is designed for calibrating the absolute spectral response of a system that uses the fibre optic integrating sphere as the sampling optic.
Recalibrating your source
The calibrated sources provide 50 hours of operation before in-house recalibration is necessary.
In-House Calibration
If you do not want to purchase one of these calibration sources, an in-house calibration service for 300-1500nm is available.
