ABSTRACT:
An adaptor for holding a micropipette in a spectrofluorimeter includes a base member for holding the micropipette and an optical system for linearly focusing visible or ultraviolet light onto a sample solution held in the micropipette. Specifically, the optical system includes a cylindrical lens which focuses collimated light from a light source into a line along the axis of the micropipette. The optical system also includes a cylindrical quartz lens which recollimates the light that emerges from the micropipette sample holder in a direction which is perpendicular to the direction of the incident light. A spectrometer is provided to receive the recollimated light for measuring the light absorption and light emission characteristics of the sample material held in the micropipette.
