The LED Industry needs technology to deposit conformal phosphors on die or optics for consistent bin control; however, it is challenging to keep the phosphor dispersion in suspension and uniformly mixed.
Nordson ASYMTEK’s Spectrum phosphor coating solution meets these challenges. The system includes air management to address safety concerns, a robust interior to minimise damage from phosphor particles, and heated tooling for your specific application.
GAO unveils Identifier with detachable InGaAs detector
The indium gallium arsenide device is suited to identifying dark or live fibre and excessive losses due to misalignment of mechanical splices or poor connections
GAO Instruments has launched a compact fibre optic identifier which provides transmission direction, multiple signal frequency identification and a detachable InGaAs detector.
The model C0230001, employs safe and reliable macro bending technology to avoid the disruption of network communications that would normally be caused due to the need to disconnect or cut the fibre optic cable for identification and testing.
The portable device offers a wavelength range of 800 to 1700 nm. It identifies signal frequencies of CW, 270 Hz, 1 kHz, and 2 kHz. The identifier is compatible with multiple adapters including Φ250 µm bare fibre, Φ900 µm tight tube fibre and Φ3 mm pigtail fibre.
It provides communication signal indications, comparison light indication and has 5 LED for signal intensity indication. The identifier has a low-voltage indicator and an automatic shutdown function when not in use. Its rechargeable lithium battery allows for more than 4 hours of continuous operation.
The fibre optic identifier belongs to GAO’s family of Optical Fibre Identifiers. Another similar product in this line is the Portable Optical Fibre Identifier which features core power display of the fibres, low bending loss and highly efficient output and serves as a tool in the installation and maintenance of telecommunication and CATV systems and other fibre networks.
The two handheld identifiers are simple, rugged, easy-to-use test instruments to detect the presence of network traffic, test tones and multiple signals and determine the direction of signal flow.
Bronkhorst reveals mini MFC for MOCVD growth
The firm’s latest device enables higher flow rates for mini Coriolis flow meters
Bronkhorst Cori-Tech B.V. has released a new model in its series of compact Coriolis Mass Flow Meters/Controllers for accurate measurement and control of (very) low flow rates.
With the introduction of mini CORI-FLOW model M15, the maximum flow range of this product line is extended from 0-30 kg/h to 0-300 kg/h. The instruments are suitable for both liquid and gas flow applications.
GAO C0230001
With a very small signal loss, normal communications can be maintained while identifying the transmission direction, speed and relative signal strength on its 5-level display.
