NoiseThe ultimate low-noise high-speed fiber-optical power meter
Packed with features, the OE-200 Fiber-Optical Power Meter is designed for a wide range of applications that require fast measurement of low light levels. It is ideally suited, for example, for CW measurements, time resolved measurements down to the µs-region and as the preamplifier for lock-in systems.
The OE-200 offers many more features than can be expected from a standard power meter, including selectable conversion gain from 103 to 1011 V/W, switchable AC/DC-coupling, switchable 10 Hz lowpass filter and the capability of manual and opto-isolated remote control. Due to its very low dark current (2pA), low noise and high speed a superb dynamic range is achieved. All this in a rugged, compact EMI-shielded case, designed with the user in mind and built to guarantee trouble free operation even in very rough and noisy environments.
Calibration traceable to NIST Standards
The high stability and low drift of the OE-200 ensures repeatable and consistent measurements even at highest gain setting. Calibration traceable to NIST Standards guarantees reliable results and interchangeability of OE-200 modules.
Applications:
- Fiber Alignment Systems
- Fast power monitoring in fiber systems
- Test of laser-diode to fiber coupling
- Linearity measurements over 10 decades
- Calibration of optical communication systems
- Time-resolved power measurements
