Max Energy Density: 150 mJ/cm2 (10 ns Pulse)
The ES100 Series Pyroelectric Sensors are designed for standard optical energy measurements. They directly convert the energy of a light pulse into a voltage pulse independent of the wavelength of the light field. Our pyroelectric sensors have a black absorption coating with a flat spectral response ranging from 185 nm to 25 μm. The detectable energy ranges from 3 μJ to 2 J with repetition rates up to 100 Hz. For best results, the detector diameter should be only slightly bigger than the beam diameter. The ES100 sensors come in three aperture sizes: 11 mm, 20 mm, and 45 mm. The calibration and identification data is stored in the sensor and is downloaded automatically to Thorlabs energy meters.
High Damage Ceramic Coating
NIST Traceable Calibration
Isolated Post Adapter Included
Max Power Density: 120 MW/cm2 (1064 nm, 8 ns Pulse)
Max Energy Density: 970 mJ/cm2 (1064 nm, 8 ns Pulse)
The new ES200 Series Pyroelectric Sensors for optical energy measurements are designed for pulsed lasers with high energy densities such as Excimer, CO2-TEA, Nd-YAG. The models feature high damage threshold, short time constants, high responsivity, and large apertures. The detector surface has a ceramic coating that is spectrally flat between 185 to 1064 nm and 3 to 25 μm. The detectable energy ranges from 500 μJ to 15 J with repetition rates up to 70 Hz. The calibration and identification data is stored in the sensor and is downloaded automatically to Thorlabs energy meters.
