Abstract:
The present invention regards a material thickness measuring device(1)for measuring the thickness (t) of non-magnetic web (3) applied to a magnetic material (5). The device (1) comprises an optical sensor device (7, 9, 45) for a first interaction with an upper side (11) of the web (3) as an optical reference element (29). It also comprises a reluctance transducer sensor device (31) for a second interaction with the magnetic material (5) as a magnetic reference element on the opposite side of the web (3). A control unit (39) is adapted for each point of measuring (P, PC) to calculate the thickness (t)from said interactions. The reluctance transducer sensor device (31) comprises a hollow conical magnetic core (41) around which circumference at least two coils (33, 35) of different diameter are mounted. The coil (33) having the smallest diameter is situated nearest the web (3) to be measured. The optical sensor device (7,9, 45) is adapted for sensing light beams (19) transferred through the hollow conical core (41) in directions which are oblique relative the plane (29) of said upper side (11).

Abstract:
A method and apparatus (20) used in connection with the manufacture of thin film semiconductor materials (26) deposited on generally transparent substrates (28), such as photovoltaic cells, for monitoring a property of the thin film (26), such as its temperature, surface roughness, thickness and/or optical absorption properties. A spectral curve (44) derived from diffusely scattered light (34, 34') emanating from the film (26) reveals a characteristic optical absorption (Urbach) edge. Among other things, the absorption edge is useful to assess relative surface roughness conditions between discrete material samples (22) or different locations within the same material sample (22). By comparing the absorption edge qualities of two or more spectral curves, a qualitative assessment can be made to determine whether the surface roughness of the film (26) may be considered of good or poor quality.

Abstract:
There are provided instruments for measuring and/or controlling the thickness of a coating applied to a substrate. An instrument embodied by the invention comprises coating removal means for removing a quantity of the coating to partially expose the surface of the substrate. The instrument also includes sensor means for emitting and detecting signals reflected from the surface of the coating and the exposed surface of the substrate to generate one or more data sets consisting of data indicative of the position of the surface of the coating and the position of the surface of the substrate. The sensor means is arranged so as to be distanced from the coating and the substrate, and is adapted to detect the signals reflected from the surface of the substrate during relative movement between the substrate and the sensor means. The data sets generated by the sensor means are processed by processing means of the instrument to determine the dry thickness of the coating on the substrate. Methods for measuring the dry thickness of the coating utilising instruments of the invention are also provided.
