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.

Absolute Wavelength Accuracy
Absolute Wavelength Accuracy is the maximum difference between the actual wavelength and the displayed wavelength of the Optical Source. Wavelength is defined as wavelength in vacuum.

Decibel (dB)
A unit of measurement of optical power which indicates relative power. A -10 dB means a reduction in power by 10 times, -20 dB means another 10 times or 100 times overall, -30 means another 10 times or 1000 times overall and so on.

Nanometer (nm)
A unit of measure used to measure wavelength of light, meaning one one-billionth of a meter

Relative Intensity Noise (RIN)
Relative intensity noise (RIN), describes the instability in the power level of a laser. The noise term is important to describe lasers used in fiber-optic communication and LIDAR remote sensing. It is the square of the (spectrally resolved) RMS optical power amplitude divided by the measurement bandwidth and the square of the average optical power, expressed in dB/Hz.

Total Return loss
In an optical fiber, the loss that takes place at any discontinuity of refractive index, especially at an air-glass interface such as a fiber endface, at which a fraction of the optical signal is reflected back toward the source. RL = - 10log10 (Preflected/Preference)
