Laser Position Sensing And Tracking: Pyroelectric Quad Detector Probes

Source: Spectrum Detector has become Gentec-eo USA, Inc.

We offer 4 models of the Quad Probe; DPQ-J-9 and DPQ-J-20 which are Joulemeter probes for use with pulsed lasers; and DPQR-9 and DPQ-R-20 which are Radiometer probes designed for use with CW and Quasi CW lasers. Each analog probe includes a 4CH preamp whose voltage output is calibrated in V/J or V/W. These probes can be used stand-alone or with our unique Digital Laser Position Monitor DPQ-4Track.

•Datasheet: Laser Position Sensing And Tracking: Pyroelectric Quad Detector Probes

We've created four new large area Pyroelectric Quadrant Detector Instruments. They include either a 9 mm or 20 mm square LiTaO3 Quad Detector mated to a 4 CH current mode preamplifier configured as a Joulemeter or Radiometer. They are designed for use with pulsed, CW or Quasi-CW sources for applications that include …tracking, alignment and position sensing. Each of the 4 Pyro elements are calibrated in V/J or V/W and can be used to measure and/or monitor energy or power. These probes are designed for use as OEM components in a instrument of your design or with our DPQ-4Track Digital Position Monitor. These probes feature broadband, LiTaO3 Pyroelectric detectors that allow use from the 0.19 to 3000 um. They are packaged in a small cylindrical housing that features an SM2 threaded front bezel which makes the addition of filters and/or optics easy. The output of the 4 CH preamp is terminated into a shielded multi-strand cable with locking LEMO connector. Please see the technical details on the back of this data sheet. A mating LEMO connector/pigtail is included with the DPQ probe if not being used with our DPQ-4Track Instrument.

Models DPQ-J-9 Joulemeter and DPQ-R-9 Radiometer include a 9 mm square, LiTaO3 pyroelectric quad detector with 50 um element separation. The detector is mounted in a TO8 package that is in turn mated to a 4 CH preamp and housed in a small, EMI shielded housing. The LEMO output cable/connector provides 4 parallel analog voltage outputs.

Models DPQ-J-20 Joulemeter and DPQ-R-20 Radiometer include a 20 mm square, LiTaO3 pyroelectric quad detector with 50um element separation. It is designed to accommodate large cross section laser beams or images. The Quad element is mounted in a compact, EMI shielded housing that includes a low noise 4 channel preamplifier. The LEMO output cable/connector provides 4 parallel analog voltage outputs.

Model DPQ-4Track …all DPQ probes are compatible with our new DPQ-4Track Digital Electronics. Please review the DPQ-4Track Instrument data sheet for complete details.
