Photodiode energy sensors

  • 19-May-2010 03:29 EDT

Ophir-Spiricon’s PD10-IR-pJ photodiode energy sensors measure very low energy, down to 30 pJ. The devices extend the low measurement capability to the near infrared range, covering from 800 to 1800 nm. They can measure energies using either a single-shot or repetitive method, up to 10 kHz. A 5-mm-aperture germanium photodiode measures pulse energies in the 200 pJ to 20 nJ range, with the lowest possible energy measurement as small as 30 pJ. The energy sensors are designed for very-low-energy commercial and military applications such as telecommunications and remote sensing.

Industrial aluminum slabs are typically produced by blending small amounts of copper or manganese in a reservoir of molten aluminum that is rapidly cooled, a process known as direct-chill casting. Variations in the way these elements solidify can yield uneven results that weaken the final product.
