Single Point Detector is available with a wide range of detectors from Deep UV to Far IR.
The Ocean Optics Single Point Detector is the ideal tool for high signal-to-noise, single point fiber optic and free-beam measurements.
A single point detector is basically a spectrometer that has a detector with no pixels. Therefore it doesn’t give a spectrum over a wavelength range, but it gives the total number of counts over the whole range.

Signal detection plays a decisive role in many applications, such as spectroscopic measuring operations. Especially in fringe ranges with minimal signal, it is important that the detector forms a perfect unit with the downstream amplifier electronics. This is the only way for the user to ascertain that he is actually detecting the measuring signal and not the noise of the detector or the electronics. A self-construction is often not sufficient in these cases.

This is why LINOS offers the photo receivers of the PR.X series. The photo receiver PR.X offers high amplification with lowest noise and optimum bandwidth. The individual components like photo diode, operation amplifier as well as resistors were selected with utmost care and assembled to a powerful photo receiver with a special electronics design. This makes the extensive and costly application of photo multipliers or similar devices obsolete for many applications.

The HgCdTe detectors can be fabricated in quadrant arrays for tracking and positioning systems, scanning systems and night vision equipment.


The quadrant arrays require a common lead between the four elements in either the X or Y direction.

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.
Our supplier, Infrared Associates can meet this demand with its custom array manufacturing.
A system, including data-acquisition electronics gives you access to a complete turnkey solution to move your experiment into the infrared.
