Capable of continuous at room temperatures, a blue-green semiconductor laser uses a 523 nm oscillation wavelength and offers a 4.5 mA threshold current. In developing the device, the engineers used zinc-magnesium-selenide for the photo layer, and zinc-magnesium-sulfide-selenide for the cladding layer. This encloses the electrons, the positive hole and the light. For this purpose, the engineers improved the proprietary manufacturing technique for the cladding layer, a process offering fine quality. A resonator surface protection film enhances the energy efficiency, enabling a suitable threshold current and a threshold current density of 1.4 kA/cm2.

The ML9927 semiconductor laser works in the 1.55 µm band, produces a single wavelength and transmits to points 100 km away. The laser will work in advanced optical communication networks that transmit data at 2.5 Gbps. In constructing the device, the engineers applied a multiple layer quantum well (MQW) structure to the active layer of the lightemitting section, using an optimum number of quantum wells. By limiting the wavelength modulation to 0.3 nm during signal modulation at 2.5 Gbps the ML9927 achieves long-distance transmission up to 100 km. Previously, the longest possible distance was 30 km at a 1nm wavelength modulation. Tests of the product show a service life at 50˚C of 100,000 hours (about 12 years).

Omeg Ltd is launching two 360˚ servo potentiometers with life spans greater than 10 million cycles – a ten-fold increase on the company’s standard design carbon track rotary potentiometers. Long life results from a new flush bonding technique for producing the resistance tracks. This process uses a polymer based conductive plastic ink which is bonded at high temperature and pressure to an epoxy substrate to produce tracks that are hard wearing and have a mirror-like finish. The potentiometers are specifically designed for industrial control applications such as servo positioning, where high speed reversals of direction or vibration are encountered.

An auto-tune beacon receiver that automatically finds the strongest beacon station transmitting DGPS error corrections and locks onto it in seconds. The receiver works automatically with all Army Corps of Engineers DGPS beacon broadcasts transmitting in the Type 9 message format, as well as all international beacon systems.
A combined GPS/beacon also available as an option, eliminating the need for separate antennas, cables and external grounding. This H-field ferrite loop antenna provides improved signal reception under poor atmospheric conditions. The unit is waterproof and can be installed in an open cockpit or fly bridge. It has a large easy-to-read screen with simple menu-driven operation. The screen has been upgraded with a transflective LCD.
