USB-controlled Optical Power Monitor

 

What could be easier?

 

The SOPM150 is a versatile power monitor for use in the lab and for laser servicing as well as for OEM applications. 

 

Highlights

 

  • Low cost and simple configuration. Basic system just includes base module, detector head, software and carrying case.

  • Easy to use

  • Powerful

  • Wide wavelength ranges: 190-950nm; 800-1550nm; 800-1650nm or 400-1650nm.

  • Bandwidth: 10 kHz

 

Properties

 

The SOPM150 is small enough to fit into your pocket and is USB powered and controlled.

 

Each head is automatically recognized and its individual calibration data are uploaded to the system. In addition, the user may load up to 5 separate filter curves. Thus, the dynamic range and functionality of the unit can be expanded while ensuring proper calibration.

 

The graphical user interface is intuitive to use and easy to read! The software includes a scope function, data logging and a large, digital display.

 

Specifications

  • USB powered and controlled 

  • 30 Hz update rate with GUI, 1500 Hz as data logger

  • 5 gain ranges from 1µW to 10 mW full scale (<1nW resolution)

Optical Power Monitor

 

Precision measurement of optical power from pW to mW. 

 

Properties

The SOPM series of optical power monitors employ photodiodes to measure optical power. Precision dual transimpedance input stages provide for high common mode rejection and linearity throughout the full dynamic range of the system.

 

Fields of Application

These optical power monitors are used for the measurement and monitoring of optical power from the UV to near IR. The output is a voltage linearly proportional to power. The fast response time at high signal-noise-ratio makes the OPM series particularly useful in systems control feedback loops, such as in fibre alignment systems. The high sensitivity and wide dynamic range allow measurement of fibre coupled lasers and LEDs alike.

 

Several options of photodiode material and optical input, including free beam input, make these units useful in a wide range of applications including non-telecom metrology. A wide variety of modules are available with TTL-compatible interfaces for full parameter control. The proprietary auto-nulling function allows up to 7V of offset nulling. This is particularly useful for eliminating a DC signal component to concentrate on signal changes, such as during component burn-in and life-time testing.

 

The amplifiers are classified according to rise time. Within each classification there are options of enclosure style, diode material, receptacles and numbers of channels. Please consult the linked documentation for full details in each case.
