Laser precision rjp-735 pyroelectric energy probe rjp
Laser Precision Corp. RJP-735 Pyroelectric Energy Probe
The RjP-700 Series probes are designed to measure lower pulse repetition rate, longer duration pulses - up to 1msec pulse width at a maximum rep rate of 40Hz. This allows for measurement of pulsed flash lamps and other sources not possible with other probes. The combination of large area detector surface and long pulse width allow for measurements up to several Joules total energy. Integrated preamplifiers allow for longer probe-to-instrument cable runs, useful for manufacturing environments.
The RjP-735 Perhaps the most versatile 700 Series probe, the 1.0cm2 cavity pyroelectric probe can measure total energy and fluence with sub- J sensitivity. The RF version extends the far-IR response into the millimeter regime.
The RjP-735 Cavity Pyroelectric Energy Probe measures J to Joules, single-shot to 40 Hz, from the UV to Far-IR - making it suitable for a wide variety of applications. The unique cavity detector assembly is a nearly perfect absorber, producing a flatter spectral response and greater sensitivity than a conventional pyroelectric detector of comparable size.
Because of its wide spectral response this probe is the ideal measurement tool for broadband sources like flash lamps and blackbody emitters. Cover the full spectral range of Ti:Sapphire, Dye, OPOs, and other tunable laser sources without having to worry about wavelength correction factors. The RjP-735 is equally adept at measuring Nd:YAG, Er:YAG, Nd:YLF, Excimer, Nitrogen, Copper Vapor, and CO lasers.
Besides being a versatile research instrument the RjP-735 is an excellent energy transfer standard. It can be used with calibrated neutral density filters to extend its dynamic range to match both low-energy semiconductor probes and high-energy thermopile probes. A removable aperture plate (RkR-700) defines the detector active area to be 1 cm , so overfilling the aperture automatically results in fluence (J/cm )measurements.
The extended UV response is well suited for photolithography, sterilization, and curing applications. Use it to calibrate ophthalmic and surgical lasers. Perform real-time analysis of LIDAR, rangefinder, and fire control systems. Or monitor the source laser in laser ablation, laser induced fluorescence, and non-linear optics experiments.
