FIELD: medical engineering.
SUBSTANCE: device has laser arranged along the optical axis and operating in red spectrum bandwidth, telescope, polarization filter, Jamin interferometer, having controllable optical wedge in one of arms, rotating Dove prism, objective and rotating mirror having manual handler. Two additional laser units are available with their wavelengths being equal to λ=400-470 nm and 500-540 nm, respectively. Saw-shaped voltage generator is connected to two piezo-engines joined to dead resonator mirrors of the additional laser units. Broadband photodiode operating in visible light bandwidth is movable along spatial arc having best vision distance radius. The device enables one to make micrometric focal plane changes of output probing laser beams with respect to probed eye lens. All laser beams are arranged coaxially.
EFFECT: wide range of functional applications in any cataract cases and any pathological color vision changes cases.
