Preamplifiers for PSDs

Amplifiers for PSDs, Differential Diodes, and Quadrant Diodes 

There are two varieties of preamplifiers available for position-sensitive detectors (PSDs).

LC-301DQD OEM module: Preamplifier boards for one and two-dimensional PSDs with three amplifier stages.

They are particularly easy to use and very flexible. The integrated timer allows the direct connection and synchronization of a laser/LED in order to generate the light spot which is to be positioned. To adjust to the intensity of the light source, the transimpedance amplifier (TIA) has three levels of operation. Customer-specific solutions are also available.

Passively-Quenched COUNT® S

New photon counters have been added to the COUNT® series: The COUNT® S modules feature the same high quantum efficiency of the other models but a significantly larger active area of 500 µm which facilitates focussing. These photon counters are passively quenched and thus the most inexpensive alternative. They are well suited for research and school internships - e.g. in the field of quantum optics and quantum information.

A dead time of approx. 1 µs yields a maximum count rate of up to 1 Mcps. The dark count rates of the COUNT® S series range model-specific between 1000 cps and 5000 cps and tie in directly with actively quenched COUNT®s.

Function: Incoming photons produce electrical pulses in the detector that are then readout using the TTL output. A PSU, which is available on an optional basis, completes the plug-and-play module. All COUNT® S models are also available with an FC/PC fiber coupling.

UV/IR viewers

LASER COMPONENTS offers a variety of UV/IR viewers that make radiation from 350 nm to 1550 nm visible to the human eye

These standard units cover the wavelength range from approximately 350 nm to 1350 nm. In addition, there is a version available for the IR range (up to 1550 nm). This enables the selection of an appropriate device to match the application. All viewers come in a transport case with batteries included.

UV/IR viewers are used in research, development, production, and medical technology. Typical applications include beam adjustment or the detection of undesired scattering.
