Rk-5700 Power Meters
The Rk-5700 Series Power Meters accept a wide variety of probes
pyroelectric, silicon, and thermopile enabling them to perform
absolute radiometry, total laser power (cw and average), and irradiance
measurements from the UV to far-IR, pW to kW. Integrated lock-in amplifier
circuitry allows for synchronous detection of chopped optical signals,
improving both S/N ratio and background rejection. The dual channel Rk-5720
simultaneously measures Channel A, Channel B, and the ratio B/A. An IEEE-488
GPIB computer interface, Analog Outputs, Background Cancel, and Autorange
are all standard features.

The Rk-3000 Series are dedicated power measurement systems consisting
of an analog power readout and a compact detector head. The readouts feature
an oversized, backlit, dual-scale analog meter, range selector knob, and
0-1VDC analog output. System options range from the Rk-3260 Silicon for
low power applications to the Rk-3115 150W Thermopile system. These rugged,
easy-to-use systems are designed to have a fast response time with minimal
overshoot for easy laser tuning.

Rk-3260 This system is based on a
1cm2, UV-enhanced silicon detector with a spectral response of 180-1100nm.
Power measurement is from pW to 1mW, and can be extended to 1W with the
3 O.D. filter supplied with the system.
Rk-3100 This "general purpose"
system uses a convection cooled, surface-absorbing thermopile detector
to measure from milliwatts to 10W, with a flat spectral response from
the UV to far-IR.
Rk-3103 Similar to the Rk-3100, the
Rk-3103 extends the power handling capability to 30W. The large surface
area, high damage threshold, and fast response time make this system ideal
for tuning and aligning mid-power lasers.
Rk-3115 The Rk-3115 uses an efficient,
high-flow cooling fan built into the compact head to continually dissipate
up to 150W of optical power. It has a 20kW/cm2 damage threshold from the
UV to far-IR.
