    Abstract: An apparatus for photometric measurement of biological liquids and a method of simultaneously measuring the presence or quantity of an analyte in a sample region are disclosed. The apparatus includes a plurality of spaced apart sample regions; a light source adapted to emit light including at least one frequency; a lens system including a light coupling system, wherein the light coupling system is disposed between the light source and the plurality of sample regions. A method is also disclosed including illuminating the sample region with a light beam emitted from a light source, wherein said light beam passes a light coupling system, the light coupling system including a telecentric element and a plurality of light mixing rods, wherein the light coupling system is disposed between the light source and the sample region such that the light beam is directed into the sample region.

    Abstract: A gas detector (10) that is arranged to sense the concentration levels of target gases oxygen, methane, carbon monoxide, and hydrogen sulphide, within a gas sample from an environment surrounding the detector. The gas detector (10) comprises laser sources (12a-12d) that are arranged to transmit radiation through the gas sample at four target wavelengths that correspond approximately to the optimum absorption wavelengths of each of the target gases and an optical detector (16) that is arranged to sense the intensity of the radiation transmitted through the gas sample at each of the target wavelengths. A control system (22) generates representative concentration level information for the target gases based on the level of absorption of the radiation transmitted.

    Abstract: An imaging device for biochemical or medical samples, the pulse mode light source of which incorporates flash lamps and a rotating mirror in an inclined position, the said mirror reflecting the light emitted by each flash lamp in turn along the same optical path to the sample. The flash lamps are switched on alternately in phases and synchronised with the rotating mirror and the emission light chopper, which comprises two rotating discs. The turning mirror directs the light at the sample from above and/or below, in which case a double-acting transparent scattering plate can be used.
