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.

*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.

Broadband Source (BBS)
A Broadband Source is a spectrally large source that emits a signal which contains a continuous range of frequencies with a broad optical bandwidth (usually 100 nm or more). Sometimes called a white light source, there are two different meanings of this term. Visible white light and a source which does not necessarily emit in the visible spectral region.

Coherence is the pattern and or relationships of waves due to phase properties.

Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Power Flatness Over Modulation
When changing the wavelength and modulation frequency, and measuring the differences between actual and displayed power levels (in dB), the power flatness is ± half the span between the maximum and the minimum value of all differences.

Singlemode fiber
Singlemode Fiber has a small core, only about 9 microns, and is used for telephony and CATV with laser sources at 1300 and 1550 nm. It can go very long distances at very high speeds. 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.
