3A-FS High Sensitivity Thermal Sensors

3A-FS

產品型號：3A-FS
產品說明：

The 3A-FS is our lowest noise thermal power/energy laser measurement sensor and has a fused silica window. It has a 9.5mm aperture and can measure from 8µW to 3W and from 15µJ to 2J. It covers the spectral range from 0.19 to 2.2µm with window installed and to 20µm with window removed. The sensor comes with a 1.5 meter cable for connecting to a meter or PC interface.

Note: (a) Depending on room airflow and temperature variations (b) Remove window for measurement beyond 2.2μm (c) 2 sigma standard lab traceable calibration for 0.6THz – 10THz. For 0.3 - 0.5THz add 4% to error. Outside this region the sensor will measure but is not calibrated. (d) Back reflections from meter can sometimes cause interference effects with source. Unit should be tilted ~10o in this case (e) For P and PF types and shorter wavelengths derate maximum energy density as follows: Wavelength Derate to value 1064nm Not derated 532nm Not derated 355nm 40% of stated value 266nm 5% of stated value 193nm 10% of stated value (f) Lowest measurable powers are achieved by thermally quiet room conditions, using removable snout, averaging and offset subtraction
