TECHNOLOGY IN ACTION ADVERTORIAL MR-16 V – the calibratable, portable CCD-based micro-spectrometer with storage battery, memory, and touch display
spectrometer. Powered by a rechargeable lithium-ion battery, the device has a size of only 148 x 96 x 35 millimeters and a weight of 550 grams. Using the included small integrating sphere or, in alternative configurations of the device, an optical fiber SMA905 input, the MR-16 V4 allows a variety of on-site measuring operations in visible light with wavelengths between 380 and 780 nanometers. Until now, these measurements were very time- consuming and confined to dedicated laboratories. MR-16 V4 measures at a resolution of 4.2 to 5 nanometers FWHM, with an integration time of 1 millisecond to 24 seconds, an SNR value below 0.3 per cent and a spectral distortion of 0.12 per cent. MR-16 V4 is based on a MEMS spectrochip for capturing the
W
photons, coupled with a linear CCD converting the photons into electrons. The digitized signal is processed by the integrated micro-computer and visualized on a multi-color touch-display. MR-16 V4 is equipped with internal memory for some 2000 measuring operations. Further data can be saved on a Micro SD card and also exported using the USB port. MR-16 V4 can be used as a universal tool for quickly checking
systems during operation, but also for quality control in manufacturing as well as tests in research environments. It is capable of spectral measurement, luminance measurement, color distribution analysis according to both CIE 1931 and CIE 1976, spectral analysis, analysis of color rendering values according to CRI and CQS, and analysis of color consistency according to SDCM (McAdam). Furthermore, MR-16 V4 can be calibrated for various parameters, such as lumen, lux, distance, PPF, etc. MR-16 V4 is suitable for a wide range of light-related measurements
required in fields such as lighting technology, display technology, automotive, medicine, architecture, energy consulting, chemistry, and biology. Two versions of the measuring device are equipped with dedicated software for additional tasks: MR-16 V4-BINS supports the sorting of LED light sources according to color, known as binning. The MR-16 V4 PPF version’s additional functionality is measuring the photosynthetic photon density. This helps users in the field of
ammes & Partner, a German light technology company, have launched MR-16 V4, a portable CCD-based high-end micro-
plant breeding with tasks such as optimizing light conditions in a greenhouse for optimum growth. Customers choose the version and preferred software configuration when ordering. Wammes & Partner have developed the MR-16 V4 micro-spectrometer in
cooperation with their worldwide network of technology partners. The experts also serve as a one-stop shop for customer-specific add-ons, updates, specialized accessories, and calibration services. In order to optimise access to the wide range of potential users, Wammes & Partner distribute the device both through their subsidiary Global LightZ, specializing in light technology, as well as the display-focused subsidiary i-sft. Depending on the version, MR-16 V4 can now be ordered from both companies at an introductory net price of 3450 euros.

High power assemblies deliver unparalleled customisation, performance and cost savings
M
olex recently launched its Polymicro Technologies Optical Fibre Bundle Assemblies. The bundle assemblies are custom configured for scientific
and industrial optical requirements, including biotechnology and pharmaceutical diagnostic equipment, semiconductor fabrication and inspection and laser welding and marking.
“Quality and accuracy are critical to measuring samples in spectroscopy, and
not easily achieved with standard assemblies,” said Teodor Tichindelean, global product manager, Molex Polymicro Technologies products. “Our high power optical fibre bundle assemblies are manufactured from raw material to final
product – in one location for consistent quality and precision performance.” Molex combines design support, fibre production and assembly of high fibre
count, high packing fraction bundles in the same location for significant cost savings. The manufacturing process maximises the number of fibres in a bundle, while minimising wasted space. Designed for use in high temperature applications requiring high power density, lamps and lasers, the fused bundling eliminates epoxy, fluorescence and interstitial spaces common in multi-fibre bundles.
Polymicro Technologies optical fibre assemblies are available with almost
any amount of fibres, including both illumination and detection fibres, in one assembly for optimal design flexibility and adaptability. The high precision fibre arrays deliver superior throughput and input-output shape conversion. The ruggedised bundling will withstand a wide variety of operating conditions.
Incorporating fused silica and precision components, Polymicro Technologies
bundled assemblies can include optical, electrical and mechanical functions, in addition to features such as micro-machined end tips, metal terminations or precision couplings. Optical fibres may be bundled at one end and fanned out in various configurations at the other. Custom end shapes can be micro- machined directly onto the optical fibre, saving bonding and coupling losses. Termination style and technique, jacketing and fibre type may be specified.
“Customer design requirements vary in complexity. Single-source Polymicro
Technologies optical fibre bundle assemblies can be tailored to a specific application and requirements for unparalleled design flexibility and cost savings,” added Tichindelean.
