Abstract
Laser scanner and method images or measures fluorescent samples on specimen slides treated with different fluorescent dyes. Motor-driveable sample table for the slides includes a laser and first optical system creating two laser beams of differing wavelength, a scanner with movable head and an optical deflection element for deflecting the beams toward the sample. Scanner has second optical system for forwarding emission beam bundles to two detectors for detecting emission beam bundles coming from the samples. A drive and counter oscillator connected to the drive by connecting rods drives the head for rapid back-and-forth movement and the counter oscillator has a mass at least equivalent to the head for compensation by opposite movement to the head. The optical deflection element causes spatial separation of two resulting focal points and a spatial separation of the two beam bundles in the direction of the detectors.
