High Sensitivity Thermal Sensors
Description:
The 12A is a sensitive thermal power/energy laser measurement sensor with low noise and drift. It has a 16mm aperture. It can measure from 2mW to 12W and from 1mJ to 30J. It has the spectrally flat low power broadband absorber and covers the spectral range from 0.19 to 20µm. The sensor comes with a 1.5 meter cable for connecting to a meter or PC interface.
2mW to 12W
Features
• Very low noise and drift to measure very low powers and energies
• Broadband and P absorbers for CW and short pulses
• Up to 12W
• Spectrally flat

Notes: (a) Depending on room airflow and temperature variations
Notes: (b) For the 30mJ energy scale measurements it is recommended to use the screw on barrel supplied with the sensor to protect from direct air flow
Notes: (c) For P type and shorter wavelengths derate maximum energy density as follows:
