The APEX Technologies TLS-APBX series tunable laser sources are high performance external cavity Littman designs combining wide tuning range, high output power and high signal-to-noise ratio. Different wavelength ranges are available between 1000 nm and 1650 nm (C+L [1500-1630nm], O [1260-1360nm] and T-band [1044-1084nm]).

These systems can be supplied as OEM modules for integration into other equipment or as stand-alone benchtop versions. The benchtop instrument has user-friendly software, a touch sensitive screen, GPIB, ethernet , RS-232 and USB controls plus external triggering input/output.

An internal wavelength etalon and single or dual optical power meters are offered as options.

These high performance tunable lasers are ideal for use in optical component analysis, R&D Testing, Optical Measurement Systems, Optical sensor/component characterisation … and many more applications.
