Ophir Optronics Inc. has enhanced the PE25 and PE50 pyroelectric heads to provide a linearity of 1%, a maximum pulse rate of 4000 Hz and a maximum pulse width of 10 ms. Designed for making pulse energy measurements of lasers, these metallic absorber (0.19 to 3.0 µm) devices measure 24 mm thick and have a high damage threshold coating for 193 nm. The upgraded PE50 pyroelectric head has an energy measurement range down to 15 µJ. The PE25BB and PE50BB black absorber (0.19 to 2.0 µm) pyroelectric heads also have been improved to measure pulse widths up to 10 ms.
