Device for measuring the characteristics of the human eye using oct technology

A device for measuring the characteristics of the human eye in the OCT technology, used for measuring eye properties, that has the following components within the optical path of the light beam:

• a light beam source with a low time coherence,
• a light beamsplitter used for dividing a single light beam coming from the light beam source into two and directing them towards the tested eye and the reference path and for directing the light beams that return from the reference path and from the tested eye, which enables the interference of those returning light beams and directing them further to the appropriate spectrometer,
• optical elements of the reference path and optical elements for directing the light onto the tested eye,
• an appropriate spectrometer comprising:
• a collimator,
• a diffraction element,
• an optical lens,
• detector,
• wherein the device is provided with additional optical means configured and suited for adjusting the spectrometer's imaging window by adjusting the spectral range of the wavelength recorded by the detector, which means are located within the spectrometer, wherein the additional optical means are selected from a group including a set of replaceable optical lenses a deformable multifocal lens, means for shifting one of the lenses in the optical lens, and an additional rotating diffraction element, or a combination thereof.
