Optical Multiplexer for Multipoint Sampling
Control and collect fiber optic measurements from up to 16 points with a single unit
Dunedin, Florida (March 23, 2007) – To tie together multiple sampling points requiring spectroscopic measurement with various probes, Ocean Optics’ Mikropack office introduces the MPM-2000 Fiber Optic Multiplexer. The high precision instrument optically couples a light source to either 8 or 16 outputs in sequential order or a spectrometer to either 8 or 16 inputs. The multiplexer can be used in a range of applications, such as chemical, pharmaceutical, laboratory and glass manufacturing, for accurate, repeatable measurements with fast switching times.
The MPM-2000 is ideally suited to settings where multiple locations need to be measured with multiple probes, all with one spectrometer channel and/or light source. It provides accurate measurements with a repeatability of 99% and optical throughput of greater than 60%.
The instrument distributes light in sequential order, with switching times between channels of less than 150 milliseconds. The instrument’s software and driver provide complete PC control. Switching order, switching delay time and system calibration are controlled easily by the computer interface.
The MPM-2000 features a precisely controlled DC motor for speed control without sacrificing power. The incremental movements are then converted to a digital pulsed output to assure exact control of sampling sequence. Each channel features a collimating lens connecting to an internal optical fiber system for efficient light collection.
The Optical Multiplexer is available in a one I/O version for connecting a light source or a spectrometer to 16 channels, and a two I/O version for connecting both a light source and a spectrometer to 8 channels each. These are available in both UV/VIS (250-800 nm) and VIS/NIR (350-2000 nm) models.
