Abstract: Device for determination of the light intensity of a light beam (7) has a beam splitter (1) and a detector (11). The beam splitter divides off a measurement beam (23) from the incident beam and the ratio of the intensity of the light in the incident beam to that of the measurement beam is measured using the detector to ensure that the ratio remains constant. Beam splitter and detector form a single unit. Independent claims are also made for: (1) A microscope; (2) A microscopy method in which the intensity of the incident illumination beam is monitored.

Abstract: The arrangement for studying microscopic preparations with a scanning microscope consists of a laser (1) and an objective (12), which focuses the light produced by the laser (1) onto a sample (13) to be studied, an optical waveguide element (3), which transports the light produced by the laser (1), being provided between the laser (1) and the objective (12). The optical waveguide element is constructed from a plurality of micro-optical structure elements which have at least two different optical densities. It is particularly advantageous if the optical waveguide element (3) consists of photonic band gap material and is configured as an optical fiber.

Abstract: The arrangement has a scanning microscope e.g. confocal microscope, and a laser formed as a pulsed laser (1). An optical component is positioned between the laser and a lens (12), where light generated by the laser is spectrally processed by a unique cycle such that a spectral illumination light is emitted from the laser. An optical fiber (20) forms the optical component, and is comprised of photonic-bad-gap material. An optical diode is provided between the laser and fiber for suppressing back reflection of light rays originated from ends of the fiber.
