Abstract
Present disclosure concerns embodiments of a fastening arrangement for an optical element (1), (8), (S), (P), (A) of an optical device, such as a refractometer for example, said optical element (1), (8), (S), (P), (A) having a three-point attachment, in addition to at least one fastening point on the inner frame (3) of the optical device (100), as implemented by means of a claw coupling (5) provided thereon to press the optical element (1), (8), (S), (P), (A) of said optical device (100), (100P), at its lateral face parallel to the optical axis, against said at least one fastening point in the three-point attachment. The disclosure concerns also a refractometer that comprises such a fastening arrangement, to be used for example in a stereochemical process to determine the concentration of a stereomer process substance.
Claims11
A refractometer acting as an optical device, the refractometer comprising:
- a plurality of optical elements comprising one or more lenses, a source of light, an analyzer, and a prism at a tip of said refractometer, the prism having an optical interface, at the tip of the refractometer, with a fluid outside the refractometer, and one or more optical lines provided by said optical elements to direct optical radiation from the source of light to said prism, through the one or more lenses in a total reflection angle, and, therefrom, to the optical interface of said prism at the tip of the refractometer, and, therefrom, to the analyzer, through at least one or more of the one or more lenses;
- and
- a fastening arrangement configured to fasten at least one of said optical elements to the refractometer, the at least one optical element having a three-point attachment and at least one fastening point on an inner frame of the refractometer, the fastening arrangement comprising a claw coupling configured to press the at least one optical element on the inner frame of the refractometer, at a lateral face of the at least one optical element parallel to an optical axis, against said at least one fastening point in the three-point attachment.
