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.

Key Benefits
pW to kW; UV to Far-IR
Synchronous (Lock-in) Detection
Single and Dual Channel
GPIB Computer Interface

Rk-3000 Series

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.

Key Benefits
Silicon and Thermopile Systems
Low Cost
pW to 150W
CW and Average Power

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.
