Abstract
An arrangement and corresponding method are provided for coupling radiation, preferably laser radiation, into a scanning head with a scanning unit in at least two dimensions. The radiation is focussed on an object via a microscope objective via at least one light-conducting fiber which is coupled with the scanning head. A collimator is arranged downstream of the fiber end at the scanning head for collimating the radiation exiting in a divergent manner at the fiber end.
Claims8
A laser scanning microscope for monitoring the laser radiation coupled into a scanning head, comprising:
- a first detection element;
- a beam splitter, wherein a portion of the radiation coupled into the scanning head is directed via said beam splitter to said first detection element;
- and
- exchangeable filters arranged in front of the first detection element in the beam path for wavelength-dependent monitoring of the laser radiation;
- said first detection element operable to generate a detection signal representing a regulating signal for adjusting the laser output, the laser intensity, or other parameters of the coupled in radiation.
A laser scanning microscope for monitoring the laser radiation coupled to a scanning head, comprising:
- a beam splitter that splits the laser radiation;
- exchangeable filters operable to select a wavelength of the laser radiation;
- and
- a first detection element operable to receive a portion of the radiation split by the beam splitter and being of the wavelength selected by the exchangeable filters, the first detection element operable to generate a separate detection signal for each scan point as an object is scanned based on receipt of the laser radiation of the selected wavelength for wavelength dependent monitoring.
