    Section 2. 1.3.1 Quick procedure to measure power and energy 1. Press the power button to turn on the MIRO ALTITUDE, which is in the right upper part of the front of the device. 2. Connect the power or energy detector to the input port of the MIRO ALTITUDE.

  • Page 8: Wavelength Adjustment

    The wavelength can be set according to the laser being used. Tap on the wavelength setting in the left-hand tab: A menu will appear which allows selection of the wavelength. MIRO ALTITUDE will then apply the calibration factor corresponding to the selected wavelength to convert the detector signal into measured values (see...

  • Page 9: Zero Offset

    1.3.3 Zero offset The power measurement of the MIRO ALTITUDE might not be exactly zero even if there is no laser beam on the sensor. The Zero button sets the detector current value to zero. Subsequent measurements will be taken based on this new zero power level.

  • Page 11: Specifications

    When low-sensitivity detectors are used for low power measurements, the application of the polarization tension can produce a measurement error. It is fundamental to use the ZERO function to redefine the zero of the MIRO ALTITUDE before taking measurements under these conditions. It is a best practice to use the ZERO function.

  • Page 29: Measurement Settings Panel

    MIRO ALTITUDE user manual - Revision 1.2 2.3.2 Measurement settings panel The options listed on the left side of the screen define the measurement settings and can be set by you. Certain settings are available only for specific detector types.
  • Page 30 When a detector is initially connected, the auto range mode will be selected by default. In this operating mode, the MIRO ALTITUDE will select the proper range according to the current measurement. It is possible to manually select a fixed range amongst those available. For maximum accuracy, when the reading is made in a manually selected range, you should always use the next highest range that will be measured.
  • Page 31 By using advanced algorithms and known physical properties of the detector, this function allows the MIRO ALTITUDE to provide a very accurate power measurement faster than the natural response of a thermopile power detector. It accelerates the natural response by a factor of up to 10. Turning off the anticipation will result in a slower response but will reduce the noise level and provide a more stable measured value in a noisy environment.
  • Page 32 QED attenuator or PH series power detectors). Toggle the attenuation setting into the correct mode so that MIRO ALTITUDE can use the correct calibrated sensitivity. By activating the attenuation setting, only the wavelengths at which the detector is calibrated with the attenuator will be available in the wavelength menu.

  • Page 33: Display Area

    Thermal noise is caused by a detector that has not been thermally stabilized, or there was a heat source in the field of view of the detector when the MIRO ALTITUDE was turned on (for example, the hand or body of the user). This feature can also be used to take relative measurements. Use this function once your power meter has achieved thermal equilibrium to ensure accurate measurements.
  • Page 34 MIRO ALTITUDE user manual - Revision 1.2 Scope display (scrolling graph) The scope display gives a quick look at the laser beam long-term stability and trend as a function of time (as could be seen on an oscilloscope). The chart x-axis is 60 seconds. When at least one minute of recording has passed, the chart will scroll to show the most recent 60 seconds of data.
  • Page 35 MIRO ALTITUDE user manual - Revision 1.2 Needle display The needle display is a simple and intuitive way to view the measured value. It is an excellent tool for laser tuning or alignment. The deflection of the digital needle is proportional to the real-time measurement. The 0 is on the left-hand side of the dial, whereas the range’s maximum value is on the right-hand side.

The unit will be determined according to the connected detector. For a wattmeter, the unit will be W for watt, and for a joulemeter the unit will be J for joule.

  • Page 51: Trigger

    MIRO ALTITUDE user manual - Revision 1.2 2.5.6 Trigger To analyze the energy of a pulse, it is important to know the measurement trigger settings to make sure all pulses are properly detected and measured. Pyroelectric and photodiode energy detectors use the trigger, as well as thermal detectors in energy mode.
  • Page 52 When the external trigger is activated, the Trigger level option turns grey as it is not used. The external trigger allows connecting an external device such as a laser with a trigger output to the MIRO ALTITUDE to trigger the pulse measurement. See the specification table in Section 1.4 for electrical and pulse duration specifications.
  • Page 53 30 J, only pulses above 3 J will be measured. Warning: if you select a trigger level with a high value, the MIRO ALTITUDE might not be able to detect all the pulses of widely varying energy levels in auto range mode. The auto range function uses the energy level of the last measured pulse to establish the range level.
