Photodetector ET series

Monitor the pulse energy and/or pulse shape of your laser at speeds up to a few GHz, at wavelengths spanning the visible and near-IR with very low noise equivalent power (NEP). BNC output connector. Wide Wavelength Coverage - Choice of Si or InGaAs photodiodes. Optimized Detec or Sizes - Active area diameters from 100 µm to 4.6 mm. Integrated Internal Bias - Each photodetector includes a long-life lithium cell. EOT's <10 GHz Photodetectors contain PIN photodiodes that utilize the photovoltaic effect to convert optical power into an electrical current. When terminated into 50 Q into an oscilloscope, the pulsewidth of a laser can be measured. When terminated into 50 Q into a spectrum analyzer, the frequency response of a laser can be measured.
