Abstract
The present invention relates generally to the field of biochemical laboratory. More particularly the invention relates to the improved and more accurate 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 there is an interface (218, 223, 233a, 233b, 238) for a changeable optical module (240), and excitation and/or emission beam is guided through an aperture of the optical module. This allows performing various types of measurements by changing an optical module without a problem lenses becoming unclean due to manual handling of the optical modules. The invention also makes possible to achieve an accurate measurement location and area within a sample.
