cronos the Power Probe: Fast, Accurate, Hi-resolution, Multiple Readings
 

     

cronos is a fully automatic laser power probe that calculates laser power by a microprocessor based measurement of temperature dynamics. Its patent pending measurement and acquisition technique self-determines the time needed to carry out a measurement: the data acquisition is triggered and stopped by detecting set heat parameters thresholds. This technique is totally free from induced errors due to time exposure determination and may allow multiple measurements without the need of absorber forced cooling.

Four models cover full scale powers from 300W to 10kW. Their innovative measurement concept cuts the time to measure and display down to about 10 s providing excellent accuracy (3%), repeatability (1.5%), high resolution (1W up to 10kW full scale) associated with a wide range of power measurement (down to 5% of full scale) on all probe models.

cronos features a large multifunction LCD that simultaneously indicates the measured power, its actual accuracy, wavelength of calibration (CO2, Nd-YAG, Diodes), max power range and low-battery. Furthermore a moving bar shows the actual absorber temperature; this informs the operator whether he can still perform one or more measurements before the absorber reaches its maximum allowable temperature. Additionally the probe status is displayed by a two colour LED, indicating the probe status: probe is ready (steady green), measurement is in progress (flashing green), measurement is over (flashing red) or cooling is needed (steady red).

cronos is operated by a single button, it shuts automatically off after 5 minutes of non operation and always stores its last measurement in memory. Two common AA batteries allow a minimum of 5000 measurements.

cronos has been ergonomically designed in all its details like the LCD display, angled to secure an optimum visibility to the operator and the balance of weights, to provide a comfortable and safe operation. The absorbers feature high damage thresholds, low reflection coatings and are factory replaceable for cost saving.

cronos has been designed to be price competitive respect to lower performance devices.
