A device () for assisting in optical characterisation of a sample fluid. The device can comprise a substrate () with at least one measurement reservoir () adapted for filling with the fluid () in a filling direction. The device () thereby is adapted for receiving an illumination beam () for illuminating the fluid () in the at least one measurement reservoir (). The at least one measurement reservoir is adapted for varying the rate of change of an optical path length of the illumination beam in the fluid. The measurement reservoir properties are adapted for providing information of an optical path length of the illumination beam in the fluid at a plurality of moments during the filling with the fluid. Furthermore a corresponding optical characterisation device is described. The invention also relates to a corresponding method.

Optical characterisation methods and systems

An optical characterisation system is described for characterising optical material. The system typically comprises a diffractive element (), a detector () and an optical element (). The optical element () thereby typically is adapted for receiving an illumination beam, which may be an illumination response of the material. The optical element () typically has a refractive surface for refractively collimating the illumination beam on the diffractive element () and a reflective surface for reflecting the diffracted illumination beam on the detector (). The optical element () furthermore is adapted for cooperating with the diffractive element () and the detector () being positioned at a same side of the optical element () opposite to the receiving side for receiving the illumination beam.

Compact catadioptric spectrometer

A method is described for providing a predetermined optical path in an optical module, the predetermined optical path being defined by predetermined optical characteristics for the optical module. a modifiable optical element is provided at a predetermined position in the optical module, thus generating an initial optical path of the optical module. The modifiable optical element comprising at least one optical interface in the initial optical path. An optical signal is detected from a radiation beam on the initial optical path of the optical module. The optical interface of the modifiable optical element is then physically modified to generate at least one modified optical interface of the modifiable optical element. The physical modification takes into account the detected optical signal so as to obtain substantially the predetermined optical characteristics for the optical module.

Method and system for optically coupling components

A method for providing an optical interface with at least one optical coupling structure for a packaged optical device is described. The at least one optical coupling structure may be, for example, wave-guides and/or microlenses. The packaged optical device includes an external alignment structure. The external alignment structure has a support means with at least one hole and at least one alignment feature. The method includes providing optical encapsulate material in the hole of the support means. Optical coupling structures, such as wave-guides or microlenses, may be provided into the encapsulation at a well-defined position relative to the at least one alignment feature of the external alignment structure. By providing the optical coupling structures directly in the material comprised in the encapsulation, a high degree of alignment accuracy is obtained.
