QE65000 Spectrometer

Scientific-Grade Spectroscopy in a Small Footprint

qe6500The QE65000 Spectrometer is the most sensitive spectrometer we’ve developed. Its Hamamatsu FFT-CCD detector provides 90% quantum efficiency as well as superior signal-to-noise ratio and signal processing speed.

QE65000’s onboard programmable microcontroller puts you in command of the spectrometer and its accessories and provides 10 user-programmable digital inputs/outputs as well as a pulse generator for triggering other devices.
The QE65000’s great quantum efficiency is not its only distinguish-ing feature. Its 2D area detector lets us bin (or sum) a vertical row of pixels. That offers significant improvement in the signal-to-noise ratio (>1000:1) performance and signal processing speed of the detector compared with a linear CCD, where signals are digitally added by an external circuit.

Because the QE65000’s detector is back-thinned, it has outstanding native response in the UV. It’s an excellent option for low light-level applications such as fluorescence, Raman spectroscopy, DNA sequencing, astronomy and thin-film reflectivity. Its TE-cooled detector features low noise and low dark signal, enabling low light-level detection and long integration times from 8 ms to 15 minutes.

The New RaySphere Solar Analysis System

raysphere1Meet the new optical measurement system for absolute irradiance measurements of solar simulators and other radiant sources. The new RaySphere from Ocean Optics measures absolute irradiance over spectral ranges from the UV to the NIR (350 to 1700 nm).

This portable system is ideal for solar simulator manufacturers and research and development labs as a tool to validate the output of installed solar flashlamps. The flash of a solar simulator is used within the photovoltaic (PV) manufacturing process for the binning of cells according to spectral response and for final PV module efficiency measurements.

The RaySphere system delivers the accuracy and resolution needed to measure and analyze the performance and stability of the flasher with ultralow jitter triggering electronics for timing the measurement to the flashes. Calibration has been validated by an accredited certification lab to ensure accurate detection, enabling evaluation and qualification of the spectral distribution of solar flashers and simulators according to the IEC60904-9 (2007) standard.

The system includes two thermoelectrically cooled detectors that perform repeatable and accurate spectral analysis of solar flashers from 350 to 1700 nm, and a second version contains a single cooled detector for measurement to 1100 nm.

RaySphere includes high-speed electronics and an intuitive powerful software interface. Brief measurement times enable detection of a complete spectrum during a flash or even during a portion of the flash. The measurement can be triggered by a fast response photodiode that reacts on the increasing intensity of the flashlight with sub-microsecond response times.

Laser Induced Breakdown Spectroscopy

Reliable, Repeatable Identification and Analysis

LIBS technology is a powerful tool for rapid, real-time elemental analysis. With LIBS, there is virtually no sample preparation, excellent portability, real-time results and sensitivity down to parts-permillion and picogram levels.
With recent advances in broadband spectral detectors, LIBS is capable of detection and
identification of a comprehensive range of metal and gemological materials, as well as biological and chemical agents, hazardous materials and more.
The application areas of LIBS are growing dramatically. From environmental monitoring to materials analysis and from forensics to pharmaceuticals, LIBS fits the bill when simple and straightforward techniques are required.

The LIBS2500plus LIBS Systems

Qualitative Measurements in Real-Time


The LIBS2500plus Laser-induced Breakdown Spectrometer Measurement Systems are detection systems that permit real-time qualitative measurements of elements in solids, solutions and gases. These broadband, high-resolution systems provide spectral analysis across a wide 200-980 nm range (depending on the system) at a resolution of ~0.1 nm (FWHM).

The LIBS2500plus is a much-improved system from our previous LIBS offerings. Advantages include the following:

  • Smaller footprint
  • Increased system sensitivity due to the elimination of internal fiber
  • Completely enclosed system — no access from the outside
  • Smaller SMA BNC-type connectors
  • Uses the HR2000+ optical bench and electronics
  • More functionality for use with external triggering options, such as delay generators


  • Broadband, high-resolution spectral analysis (200-980 nm at 0.1 nm resolution)
  • All channels operate from a single clock (~ 20 ns jitter)
  • Real-time qualitative measurements
  • Sensitivity to parts-per-billion and picogram levels is possible
  • Applications include materials analysis, environmental monitoring, forensic and biomedical studies, art restoration and more

How the LIBS2500plus Systems Work
A high-intensity, pulsed laser beam is focused on the sample area, positioned a few centimeters to a meter from the sample. A single 10 nanosecond-wide laser pulse is all that is needed to excite the sample. When the laser is fired, the high-temperature of the laser creates plasma. As the plasma decays or cools (~1.0 µsec after the laser pulse), excited atoms in the plasma emit light of characteristic wavelengths distinct to the element. All elements emit in the 200-980 nm region. The detection systems use up to seven of our HR2000+ High-resolution Miniature Fiber Optic Spectrometers, each with a 2048-element linear CCD array. All spectrometers are triggered to acquire and read out data simultaneously. The detectors in the broadband (200-980 nm) LIBS2500plus collect the signal; software included with the system displays the data.

Advantages of Broadband LIBS Techniques
Most traditional LIBS detection systems have a small spectral range. The LIBS2500plus Systems provide broadband spectral analysis. Because the systems are noninvasive, users can perform real-time measurements in situ, within hostile industrial, chemical and biochemical environments with little or no sample preparation. Since the LIBS2500plus utilizes Ocean Optics’ HR2000+ High-resolution Miniature Fiber Optic Spectrometers, the detection systems are portable and can be interfaced to a notebook PC via a USB port.

The LIBS technique is useful for a variety of applications:

  • Environmental monitoring (soil contamination, particulates)
  • Materials analysis (metals, plastics)
  • Forensics and biomedical studies (teeth, bones)
  • Military and safety needs (explosive particles, chemical and biological warfare agents
  • Art restoration/conservation (pigments, precious/ancient metals)
