    摘要： An optical gas detector (20) in metal or other suitable material, comprising a cup-shaped body (1), with upper mouth (9) closed by a lid (2) the bottom of which (8) is flat and provided with a plurality of through holes (15) variously arranged, which place said detector (20) in communication with the outside environment, and inside which an IR source (10) and an IR analyser (11) are placed, borne by an overlying circuit board (12). The inner lateral surface of the body (1) forming a first reflector wall (6) having a regular or irregular annular extension and defining, in conjunction with a second convex or concave reflector wall (7, 7') of a shaped appendage (5) and with one or more reflectors (3, 3', 21, 22, 23,24,25) pre-inserted and positioned in the body (1), a multiplicity of geometrically alternative optical paths (4, 4', 4", 4"') of the electromagnetic radiation emitted by the IR source (10) and detected by the IR analyser (11).

    摘要： A measurement system (5) comprises a radiation source (10) and a detection system (15), wherein the radiation source is arranged such that radiation from the radiation source is incident on a sample (25) and the detection system is configured to receive at least part of the radiation via the sample, wherein the system is reconfigurable so as to vary a path length that the radiation travels through the sample and/or a reflectance of at least one surface upon which the radiation is incident after passing through at least part of the sample. A prop¬ erty of the sample may be determined based on at least the first and second measurements.
