The present invention relates generally to the field of biochemical laboratory. More particularly the invention relates to more reliable, intelligent instrumental features of equipment used as e.g. fluorometers, photometers and luminometers. The object of the invention is achieved by providing an optical measurement instrument where a selectable optical component is identified by the measurement instrument. The instrument therefore has means for identifying an optical component by e.g. reading a code from the component. The object is also achieved by a changeable/selectable optical component such as optical module or filter for a measurement instrument, the component comprising a readable identification means. The identification comprises information on the type/properties of the optical component so that the components suitability for a selected measurement can be verified.
An optical measurement instrument for measuring samples, comprising an illumination source for forming an excitation beam, a detector for detecting an emission beam, optical components with a purpose of directing the excitation beam received from the illumination source into the sample and/or directing an emission beam received from the sample to a detector and/or filtering the excitation and/or emission beam, characterized in that at least one of said optical components is changeable and the instrument comprises means for identifying said at least one changeable optical component.
A changeable optical component for an optical measurement instrument, characterized in that the component comprises means for providing identification information on the optical component.
A changeable optical component according to claim 42, characterized in that the said code is a bar code.
A process for measurement of samples with an optical measurement instrument comprising at least one measurement head, possible means for providing excitation of a sample and means for measuring an emission from the sample, the process comprising the phases of
A method for optical measurement of samples comprising the step of transmitting excitation/emission beam between the sample and a measurement head of an optical instrument, comprising transmitting said beam through a selectable optical component, characterized in that identification information is read from at least one said selectable optical component and the optical component used for the measurement is determined on the basis of read information.
