for application in the spectral range between 200nm and 2300nm

Enormous Analysis and R6D activities have untertaken w.r.t. UV fibers. The purity and the lack of material- and surface defects show significant importance. Meanwhile some reasonable initial design fibers are available.

a) SM or LM fiberswith caw diode laser in violet / UV- A

b) microstructured SM fibers show significant resistance against 100mW input power at 405nm.

Still much remains to be done in UV fiber R&D.

The new series of 2,6µm Cut-off completes the OEC Extended InGaAs Photodiodes Series.
In addition to the 50% Cut-offs of 1,9µm, 2,05µm and 2,2µm a new Cut-off Wavelength of 2,6µm can be supplied for the round active areas with 0,5mm, 1mm and 2mm diameter. These detectors show an excellent value for the money ratio.

OEC supplies these detector with receptacles, with fibres, with TE-coolers and as bottom detector in sandwich detectors.

The JSIR450 is a wide band and powerful Infrared-Source. It has a big radiation power in the IR-band up to 15μm. In contrast to glow spiral emitters a circular homogeneous temperature distribution is reached. The JSIR450 has a broad spectral range output with high intensity. A high electric power consumption is possible within long lifetime. The JSIR450 works e.g. in infrared spectroscopy, gas detection systems, air quality and environment monitoring and in medical gas monitoring.

The IAV–Series InGaAs APDs offered by OEC can be operated in the Linear-Mode and due to the spectral range of 800nm – 1700nm in the eye-safe region as well.

Recommendation

Our amplifier technology (i.e. atto series) perfectly fits to the IAV-200. the resulting photo-receiver can be tailored to customers and application requirements providing an ultimate signal-to-noise ratio within the signal level and signal bandwidth to be measured. OEM designs will be supplied.
