- Compact, Modular Design
- Integral 1" (25mm) Filter Holder
- Variety of Detectors
The RkP-400 Series probes consist of a compact detector assembly, or
head, and a preamplifier housed in a separate enclosure. The external
dimensions of all the 400 Series Probes are the same, with identical
detector planes, allowing for easy interchange of probes in an experiment.
The heads have both ¼-20 and M6 tapped holes, a built-in 1"
(25mm) filter holder, and a side-mounted BNC connector. Probe specific
data, including spectral response curves and calibration dates, is stored
in the preamplifier for access by the instruments.
RjP-445 Optimized for high pulse
repetition rate sources, the RjP-445 pyroelectric probe measures true
energy per pulse up to 1kHz. Broadband spectral response, µJ sensitivity,
and 1 cm2 active area make this the probe of choice for fast lasers.
RjP-465 This 1.0cm2, UV-enhanced
silicon probe has picojoule sensitivity (fJ resolution) from 180 - 1100nm,
perfectly suited for low-energy LIDAR and target designation applications.
Model RjP-466 extends the maximum pulse repetition rate from 500Hz to
RjP-485 The only large-area (5mm
diameter) InGaAs energy probe available, the RjP-485 offers picojoule
sensitivity, superior thermal stability, and 200Hz speed in the mid-IR
(0.7-1.8µm) wavelength range - the best choice for calibrated
eye-safe laser measurements.
RjP-495 Covering the same wavelength
range as the RjP-485, the RjP-495 Germanium energy probe combines sub-nJ
sensitivity, 200Hz pulse repetition rate, and a large (>1.0cm2) detector
active area for maximum versatility and ease of use.
- Integrated Preamplifiers
- High Speed Operation
- Measure Total Energy and Fluence
The RjP-600 Series energy probes integrate the detector and preamplifier
in the same enclosure, thereby maximizing signal integrity between the
detector and preamplifier. This permits longer cable runs between the
probe and instrument, as is often necessary in production environments.
Probe specific information, like calibration date and wavelength response
curves, is stored in the probe for access by the instrument. Other features
include interchangeable filter holders and ¼-20 mounting hole.
RjP-637 This cavity pyroelectric
probe extends pulsed energy measurements to 500Hz. An exceptionally
flat spectral response and precision 1.0cm2 detector aperture make it
easy to measure pulsed radiometry and fluence from µJ to Joules.
Model RjP-636 allows for longer pulses (200µs) at a lower rep
RjP-667 This UV-enhanced silicon
energy probe is ideal for monitoring low-energy, pulsed sources in an
industrial environment. It features UV to near-IR (180-1100nm) wavelength
response, picojoule sensitivity, and a maximum pulse repetition rate
of 500Hz. Model RjP-668 extends the maximum pulse repetition rate to
- Large Area Detectors
- Long Pulse Capability
- Integrated Preamplifiers
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 flashlamps 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.
RjP-734 This large, 5.0cm2 cavity
pyroelectric probe is ideal for pulsed laser diode, LED, or other diverging
light sources. The cavity configuration has a flat spectral response
from the UV to far-IR, and is capable of measuring 10µJ to 2J
RjP-735 Perhaps the most versatile
700 Series probe, the 1.0cm2 cavity pyroelectric probe can measure total
energy and fluence with sub-µJ sensitivity. The RF version extends
the far-IR response into the millimeter regime.
RjP-736 This 50mm diameter pyroelectric
probe is designed for high-energy, large-area beams like those produced
by Excimer lasers. Capable of withstanding 10J per pulse, the RjP-736
can be used to monitor industrial lasers.
RjP-765a Incorporating a UV-enhanced
silicon detector with picojoule sensitivity (fJ resolution) from 180
- 1100nm, this probe is perfectly suited for low-energy flashlamp, laser
rangefinder, and target designator measurements.
