Horiba Jobin Yvon provides a full range of CCD arrays for scientific and spectroscopic applications.

These detectors are well suited to be connected to a Horiba Jobin Yvon spectrograph, but can also be used in a stand-alone configuration.
There are several options in terms of the CCD-chip. This is due to the advantages that each type of chip has. All chips can be offered with thermo-electric cooling, for applications where light levels are moderate to low.
For very low light applications, liquid nitrogen cooled chips provide the ultimate removal of thermal effects and allow measurements over extended periods of time.

LN2-cooled CCD's are controlled via the Symphony controller, TE-cooled detectors are provide in the self-contained Synapse format. Through the Symphony/Synapse interface these multichannel detectors offer high quality data that can be read out at very high speeds, thus offering possibilities for high repetition rates and increased productivity.

Beyond the visible and near infrared spectrum, CCD inherently has a cut-off where the energy of the incoming photon cannot bridge the bandgap anymore.
Since the near IR region between 1100 nm and 1700 nm often also contains very interesting information in a spectroscopic sense, it can be worthwhile to have a detector for this range alongside a CCD-based detector.

A solution based on InGaAs semiconductor material proves to be the most effective at this, offering sensitivity between 800 nm and 1700 nm. Various single line formats are available, offering the potential for very high repetition rate NIR spectroscopy, provided that there is enough light present.
Unfortunately, InGaAs is inherently susceptible to thermal influences, and therefore cooling is required to eliminate counts from this origin as much as possible.

InGaAs arrays from Horiba Jobin Yvon present the forefront of suppression in this respect, and are available in both TE-cooled and LN2-cooled detector formats.

For events that are occurring in the nanosecond regime, and which are transient, it can be useful to consider Intensified CCD (ICCD) detectors.

At the heart of every ICCD detector from Horiba Jobin Yvon is a gain stage. The gain stage consists of three distinctive parts: the photocathode, on which the photons will be incident, where electrons will be generated; the microchannel plates, which will receive the photo-electrons from the photocathode and which will amplify the incoming electrons by a large factor; and a phosphor screen, on which the electrons will be incident, thus generating light again.
The phosphorous screen is coupled with fibers to a thermo-electrically cooled spectroscopic grade CCD.

The high voltage, which is needed for the correct operation of the microchannel plates, can be switched on a nanosecond scale, and thus it is possible to sensitize the detector only for a short period.

Special classes of solid-state detectors for very specific applications are Mercury Cadmium Telluride devices.These devices can be manufactured with varying stochiometries to yield detectors that can be sensitive to very long wave infrared radiation.

These devices enable the detection of infrared radiation with relatively high efficiencies. However, due to internal mechanisms these devices are heavily susceptible to high surrounding temperatures.
Cooling to liquid nitrogen temperature will negate much of these effects.
Available in both single channel and multi-channel versions, a host of applications can be covered. Consider for instance the use of MCT-detectors in absorption spectroscopy, 2-D vibrational spectroscopy and ultrafast pump-probe spectroscopy.

Especially with certain types of spectroscopy, it can be beneficial to have a two-line array.
