NEWPORT 818-SL Low-Power Silicon Cylindrical Detector

The Newport 818-SL Low-Power Silicon Cylindrical Detector optics are designed to address the problems associated with measuring coherent light. In ordinary detectors, coherent light causes reading errors across the detector surface and measurements are more sensitive to thermal drift. This results in an additional, unreported 5% to 8% calibration uncertainty when making laser power measurements. Newport’s detector design eliminates these problems for stable, uniform detector response. Specifications. Spectral Range: 0.4 to 1.1 µm. Power, Average Max w/ Attenuator: 2 W/cm^2. Power, Average Maximum w/o Attenuator: 2 mW/cm^2. Pulse Energy, Maximum - w/ Attenuator: 1 µJ/cm^2. Pulse Energy, Maximum - w/o Attenuator: 1 nJ/cm^2. Accuracy at constant temperature: ±2% @ 0.4-1.1. Uniformity: ±2%. Linearity: ±0.5%. Saturation Current: 4.6 mA/cm^2. Responsivity: >0.1 A/W, 400–1000 nm. Responsivity (Peak): >0.5 A/W @ 920 A/W. Rise Time: <= 2 µs. Shunt Resistance: >=2 M-Ohm (typ). Die Capacitance: 12,000 pF. Reverse Bias, Maximum: 10 V. Material: Silicon.

*This is a Web introductory price for one calibration of the NEWPORT 818-SL. Price does not in most cases include measurement performance data. 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
