For indoor use only. Notes on equipment safety The TCF-1 and TCF-2 devices have been designed, manufactured, and tested to conform to the safety regulations for measurement- and control-equipment DIN EN 61010-1 (IEC 1010-1) and satisfies the relevant requirements of EEC Directive 73/23. -

100 GHz, as seen by means of a high contrast Fabry- Pérot interferometer. The red curve shows the theoretical transmission curve of a TCF-1 unit. The TCF strongly attenuates these modes, in many cases reducing them below the detection threshold. -
Page 4: Instrument Layout And General Description Of A Tcf-1
Instrument layout and general description of a TCF-1 Fig. 2 : images of the TCF-1 device; letters indicate the various components described in the text. Images of the device are shown in Fig. 2: the small etalon plate is mounted and sealed in a container, fixed inside a cylindrical cavity in the main unit body (A). -
Page 5: Output Stabiliser For Tcf-2
The TCF-2 is an evolution of the basic device, including an additional component: the stabiliser. The stabiliser provides additional stability of the output with respect to temperature and slow beam wavelength fluctuations. TCF-1 units can be upgraded to TCF-2 by adding the stabiliser. -
Page 6: Device Alignment And Installation
Device alignment and installation The TCF has been calibrated at the factory and mounted before shipping. In order to use the device, users only need to align it correctly with the laser beam and carefully regulate the temperature set point. In order to obtain the best performance, the etalon plate needs to be aligned orthogonally to the laser beam and the temperature precisely tuned on a transmission maximum. -

these degrees of freedom, a perfect superimposition of the back reflected laser spot with the incoming beam should be reached. When the alignment is perfect, some laser sources could start having large power fluctuations on the output: if this happens, rotate slightly the head so that the back reflected beam does not fool the laser source feedback circuitry. -

to check the device indicator, which should be at the middle position when an equilibrium has been reached. To allow a complete stabilisation and find a precise stable condition, check again the transmission after 20-25’: if decreased, adjust again the set-point knob. By repeating this procedure 2 or 3 times, a precise tuning of the transmission maximum will be obtained. -

If the knob set point gets too far from the maximum output setting, the stabiliser could be unable to reach the maximum output. In this case, switch it off and adjust the knob manually. It is possible that the RGB LED indicator turns red or blue if the correction voltage provided by the stabiliser is relatively large: this is not an indication of problems in the TCF circuitry, but could also be a reason to adjust the static set point position. -

Once the stabiliser is removed, use a M1.5 hex key to loosen the retaining grub screw on the TCF head, whose pressure keeps the etalon container in position. Pull the etalon container by means of a soft tip and slide it out from the TCF head;...
