Light Sources
Ocean Optics light sources provide illumination and excitation sources in the UV, VIS or Shortwave
NIR range for absorbance or reflection measurements, discrete line spectra for wavelength calibrations,
and calibrated absolute intensity standards for irradiance measurements. Wall transformers are
supplied for laboratory use. Except for the deuterium lamps, all sources are powered by +12 VDC to
facilitate their use in the field. The S1024DW accepts light energy and disperses it via a fixed grating
across the array, which is responsive from 200-1100 nm. Though some light sources emit energy
<200 nm, or emit energy to 2
µ
m, their use with Ocean Optics spectrometers is limited by our
detector’s responsivity (200-1100 nm).
The D-1000 Deuterium Light Source is a high-output, fiber optic
light source optimized for the UV. It produces intense, continuous
spectral output from ~200-400 nm.
The DT-1000 Deuterium Tungsten Halogen Light Source combines
the continuous spectrum of a UV and VIS/NIR light source in a
single optical path. Its output range is ~200-1100 nm.
The LS-1 Tungsten Halogen Light Source is a versatile source for the
VIS-Shortwave NIR (360 nm-2
µ
m). It offers high color temperature, a
long life and a built-in filter slot for color-correcting and other uses.
The LS-1-CAL Calibrated Light Source is a NIST-traceable
calibrated light source for the VIS-Shortwave NIR (300-1050 nm).
It has a highly Lambertian internal diffuser, and is specifically
calibrated for optical fibers. The calibration data includes absolute
intensities at the fiber entrance port for wavelengths between
300-1050 nm.
The PX-2 Pulsed Xenon Lamp (~225-700 nm) is a 220 Hz short-arc
flashlamp. It produces high-energy pulses of brief duration and has two
trigger modes for the hardware or software controlled flash rate.
The HG-1 Mercury Argon Calibration Source produces Mercury and
Argon emission lines from 253-922 nm for use in performing fast, reliable
spectrometer wavelength calibrations.
