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.

Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

dBm
Optical power referenced to 1 millimatt

Multimode Fiber
Multimode Fiber has a large core (almost always 62.5 microns - a micron is one one millionth of a meter - but sometimes 50 microns) and is used with LED sources at wavelengths of 850 and 1300 nm for short distance, lower speed networks like LANs. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Refractive Index
The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium. The velocity at which light travels in vacuum is a physical constant, and the fastest speed at which energy or information can be transferred. However, light travels slower through any given material, or medium, that is not vacuum.

Total insertion loss
A measure of the loss of light within an optical component
