Pulse Energy Heads measure high laser pulse rates.

Press Release Summary:

Models PE25 and PE50 Pyroelectric Heads (metallic absorber 0.19 to 3.0 µm) are 24 mm thick, with maximum pulse rate limits to 4,000 Hz and linearity of 1%. Model PE50 has lower limit energy measurement range of 15 µJ. Models PE25BB and PE50BB (black absorber 0.19 to 2.0 µm) Pyroelectric Heads can make measurements of pulse widths up to 10 mS.

Original Press Release:

New Generation of Pulse Energy Heads Now Have Extended Performance Characteristics

o Linearity reduced from 2% to 1%
o Maximum Pulse Rate extended to 4,000Hz
o Head thickness reduced from 33mm to 24mm
o Maximum Pulse Width extended to 10mS
o New HD high damage threshold coating for 193nm

Danvers, MA August, 2002...Ophir Optronics, Inc. announces a new generation of high performance enhanced PE25 and PE50 Pyroelectric Heads, used to make pulse energy measurements of lasers. The new generation PE25 and PE50 (Metallic absorber 0.19-3.0µm) offer maximum pulse rate limits to 4,000Hz, twice the previous limit for these heads. The linearity specification has also been improved from 2% to 1%. In addition, the thicknesses of the Pyroelectric Heads have been reduced to 24mm from the previous 33mm design.

The new generation model PE50 Pyroelectric Head has further reduced the lower limit energy measurement range from 40µJ to 15µJ.

The new generation PE25BB and PE50BB (Black absorber 0.19-2.0µm) Pyroelectric Heads maximum pulse width measurement range can now make measurements of pulse widths up to 10mS, as compared to the previous limit of 3mS.
