Abstract: The present technology relates generally to fibre optic cables their manufacture and uses. The technology has useful applications e.g. in the field of optical measurements such as biochemical laboratory instrumentation for measuring properties of samples on microtitration plates and corresponding sample supports. The technology has also applications in various laser technologies. The object of the technology is achieved by providing a fibre optic cable wherein an active surface with a determined form is provided at a first optical interface at the first end (451a, 451b) of the cable. The first end of the cable is fused into an exemplary circular form, the fused cable end including fibre ends both within the active surface and outside the active surface. At the opposite, second end of the cable, those fibres which have their first ends at the determined active surface area, are used for forming a second optical interface (452a, 452b). This way it is possible to have high transmission efficiency in optical interfaces where other than circular cross section of the light beam exists.

Abstract: An optical power control system for a semiconductor source spectroscopy system controls power fluctuations in the tunable signal from the spectroscopy system and thus improves the noise performance of the system. This general solution has advantages relative to other systems that simply detect reference power levels during the scan and then correct the detected signal after interaction with the sample by reducing the requirements for coordinating the operation of the sample detectors and power or reference detectors. The spectroscopy system comprises a semiconductor source and a tunable filter. The combination of the semiconductor source and tunable signal illuminate a sample with a tunable signal, being tunable over a scan band. The power control system comprises an amplitude detector system for detecting the power of the tunable optical signal and power control system for regulating the amplitude of the tunable optical signal in response to its detected power.

Abstract: A method and apparatus for measuring isotherms and determining solid state phase changes comprising a humidity generator having a temperature controlled internal chamber, a microbalance mounted externally to the internal chamber and a near infrared spectroscopy (NIRS) probe or Raman spectrometer probe mounted internally in the internal chamber, such that the mass of a sample suspended within the chamber and its solid state phase can be determined without disturbing the controlled environment surrounding the sample. The humidity generator includes means for controlling humidity and temperature within the internal chamber, an access port that extends into the internal chamber. The balance is situated near the port such that the balance mechanism extends within the internal chamber. The balance mechanism utilizes a means for holding a sample within the chamber such that the mass of the sample can be determined as it equilibrates to the temperature and relative humidity maintained within the internal cavity. The NIRS probe extends from a NIR spectrometer. Similarly, the Raman probe extends from a Raman spectrometer.
