NEWPORT 2931-C Dual Channel Optical Meter

The Newport 2931-C 2-channel input optical meter is designed to provide a powerful combination of features to measure optical power and energy of near-monochromatic or monochromatic sources. The model 2931-C optical meter is compatible with all Newport detectors having a 15-pin D-sub type connectors. It is designed to provide continuous wave (CW) and pulsed source measurements that support the testing and production needs of free space beams and fiber optics based sources. The full color TFT 5.6” LCD renders excellent visibility both with the naked eye and laser goggles for single screen rendering of plotted and enumerate results. Measurements can be displayed in W, Amps, dBm, dB or relative units, either directly or as relative ratio measurements from present or stored values. Statistical capabilities include the computation of Min, Max, Max-Min, Mean and Standard Deviation. Additional features such as digital and analog filtering, and data storage of up to 250,000 readings per channel are also offered. Features. Compatibility with low-power, photodiode detectors (Si, Ge, InGaAs and GaN) and photo-multiplier tubes (PMT). Up to 20 kHz repetition rates for photodiode detectors with signal sampling rates of up to 250 kHz. Multiple measurement modes for power measurements: Single, Continuous and Peak-to-Peak. Software suite, including LabVIEW drivers, .NET programming capability and high-speed data transfer utility. 250,000 of internal data point storage and external USB flash-memory compatibility. Triggering features to synchronize measurements with external events. USB and RS-232 Interfaces.

Coherence Time
Average time for the wave train to lose its phase realtionships

Fiber Bragg Grating (FBG)
A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by adding a periodic variation to the refractive index of the fiber core, which generates a wavelength specific dielectric mirror. A fiber Bragg grating can therefore be used as an inline optical filter to block certain wavelengths, or as a wavelength-specific reflector.

Modulation
Modulation is the process by which the characteristic of one wave (the carrier) is modified by another. Adding information into pulses of light.

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Stability
Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, such as a fiber optic transmission system, remains fixed with the passage of time or with varying environmental conditions.
