Compact UV spectrometer for education and research.


Entry Level Diode-Array Spectrometer for Education and Research

The TIDAS® E series has been developed especially for education and research. This instrument range provides ease of use of the diode-array spectrometer and flexible optical fiber technology, at a reasonable price. The diode-array technology makes these instruments fast, precise and universally applicable.

The TIDAS® E spectrometer series enables fast and efficient application of diode-array spectroscopy. They combine a detection system with an integrated light source, using the patented integrated dual cuvette holder and the option of the coupled external fibre optic. External accessories such as sample or filter changers are energised through control wires and triggers. Through LAN connections, the TIDAS® E is efficiently integrated into the existing network or connected directly to the computer.

The TIDAS® E UV system is distinguished by high sensitivity combined with minimal stray light. It is suitable for measurement tasks in the wavelength range from 190 nm to 390 nm; a D2 light source is integrated.

Plug und Play – with help of standard accessories the TIDAS® E sits ready to be immediately operational

Increased Flexibility – the patented cuvette holder allows a variety of measurement configurations that are seamlessly integrated within one instrument

Diode Array Technology – enables quick and precise measuring with a low level of scattered light

Software – modular and user friendly, permits the data acquisition and evaluation of individual tasks


With the TIDAS® E, the following measurement setups are possible without any need for instrument modification:

  • Cuvette measurements
  • External measurement setups, for example using immersion probes or flow cell measurements
  • Layer thickness measurement through white-light interference
  • Colour measurement and evaluation
  • Absorption and fluorescent measurement
  • Scattered light measurement

Selected measurement cells, light guides and ready-to-use applications complete the programm range.

The TIDAS® E spectrometers are designed as compact and transportable fiber-optic spectrometers with integrated light source and a patented dual port cuvette holder. With a single change of a mirror cuvette, absorbance, reflection and fluorescence measurements can easily be performed internal or with external immersion probes and reflection measurement heads in conjunction with either the internal or an external light source.

Another highlight of the TIDAS® E instruments is the single Ethernet interface which allows them to be easily incorporated into existing network environments. Trigger and control cables allow the coupling and control of external devices such as specimen or flter changers and light sources.

Even though the TIDAS® E is the entry level spectrometer from J&M, it is of high quality resulting in a sensitive instrument, with low noise and low drift. The TIDAS® E is a compact instrument which offer excellent value for money.

Lighting the way – The TIDAS® E Optical Path

The TIDAS® E demonstrates its flexibility with various measuring setups

With help of the patented cuvette holder and the mirror cuvette, various measurement setups are possible in conjunction with either the internal or an external light source.  The patented cuvette holder and the external measurement setup can be used simultaneously. The flexibility of the design of the TIDAS® E manifests in various possible options of measurements using different optical paths formed by combinations of cuvette holder, mirror cuvette, optical fiber and light sources:

Measuring with Internal Light Sources and Internal Cuvette Holder

Possible Measuring Experiments:

  • Cuvette measuring in absorption/transmission

Optical Path:

The light radiates from the internal light source, and is conducted from the redirected mirror, through the cuvette holder, into the correct detector.  The measuring sample can be located in the second cuvette chamber.

Measuring with the Internal Light Source and External Fibre Optic Connector

Possible measuring experiments:

  • Measurement of exterior measurement cells, for example immersion probes, external cuvette holder, flow cell measurements, and more
  • Fluorescent excitation with band-pass filter
  • Scattered light measurements (only possible when the mirror cuvette is removed and both external fibre optic connectors are bypassed)

Optical Path:

From the internal light source, radiated light passes through the cuvette holder and illuminates through the external measuring cell.  The light is redirected through the cuvette holder and channelled through the detector.

Measurement with Laser for Florescence Excitation as External Light Source

Possible measuring experiments:

  • Cuvette measurement in absorption/transmission with an external light source

Optical Path:

The light from the external light source is coupled over the cuvette holder and redirected over the mirror cuvette to the detector; thereby the sample in the standard cuvette chamber can be measured.

Measurement with Laser for Fluorescent Excitement as External Light Source

Possible measuring experiments:

  • Detection with an external measurement setup (external light source and/or external measuring cell)
  • Fluorescence excitement through external monochromatic light source (only possible when the mirror cuvette is removed)

Optical Path:

The light from the external light source is coupled over the cuvette holder and redirected over the mirror cuvette to the detector.
