IMAGING, MICROSCOPY AND SPECTROSCOPY
For optical coupling of the various CCD and ICCD cameras, several adaptors such as C-monunt, F-mount, or customized (for various microscopes, imaging spectrographs etc.) are available. Please contact for more details.
for diffraction limited resolution imaging at high magnification and long working distances Based on high speed, high resolution Cassegrain catadioptic design.
QM 100: 1.5µm @ 15 cm; QM 1: 3µm @ 55cm; DR1: 12µm @ 300cm
TauTec offers Dual/Quad View Image splitters from Optical Insights Inc. for simultaneous dual or quad channel imaging on the same CCD cameras.
We also offer optical setups for simultaneous multichannel imaging using multiple detectors (PMTs or CCD cameras).
The Image Doubler is a stereoscope and provides the projection of an image pair onto one camera. Filters can be inserted for each image separately.
For spectral imaging, the CCD/ICCD cameras can be conveniently coupled to imaging spectrographs. TauTec offers and supports imaging spectrographs from different vendors.

This compact unit is designed for the critical timing adjustment of fast instruments. It will delay an arbitrary input signal over an adjustable range of 20 ns in 25 ps steps and consists of a set of switched 50 ohm calibrated delay lines together with a controlling microcomputer. These is no inherent jitter. The rise time is about 500 ps and has a high voltage capability for short pulses. The delay is set from the front panel or from an RS 232 remote control interface. Current delay setting is shown on LCD display with relative or absolute delay mode. The delay is achieved by the switching in and out of sections of delay line by matched relays. The unit will be useful in such applications as the adjustment of timing of fast cameras and triggering or pulse shaping in laser systems.
Delay Generator: The delay generator provides pulse delay times from the ns range to the µs range with a delay resolution down to 2.5 ps. Its low jitter and short intrinsic delay makes it useful for a variety of triggering and pulse shaping applications.
The compact optical trigger unit has been designed to provide stable trigger pulses from optical pulses with unstable amplitude.The principle of operation is as follows: the photodiode converts the input optical pulse into an electrical signal. The electrical pulse is then shaped by a linear electrical network to yield a bipolar zero-crossing pulse. The zero-cross trigger unit generates an output pulse with a well defined amplitude and duration. To avoid triggering of zero-cross trigger unit by small noise pulses, an additional leading edge threshold discriminator is used which enables the zerocross trigger unit only if the input amplitude exceeds an adjustable threshold. Thus the threshold discriminator decides whether the circuitry triggers but the timing is determined by the zero-cross trigger unit.
It is often necessary to produce a trigger signal that is synchronised to an RF waveform but occurs at a random time. The Trigger Resynchroniser will produce a low jitter output synchronised to the RF at a time after a trigger signal is received.
For normalization of images due to laser energy fluctuations
The Online Energy meter is designed for measurement of laser pulse energy. It is capable of measuring the energy of individual laser pulses from a burst and simultaneously with the acquisition of CCD images. The online energy meater may be used as a stand-alone unit or within a complete optical diagnostic system. The simultaneous acquisition of camera images and laser energy increases the accuracy of measurements based on absolute quantification of e.g. LIF signals. Correction for the laser energy variations can be performed by software either online or using batch processing routines.
