Abstract: The present disclosure relates to an apparatus for multi-mode imaging of an eye. The apparatus integrates at least two modes namely OCT, hyper-/multi-spectral imaging, and RGB/IR. The apparatus captures high resolution and larger dynamic range OCT and hyper-/multi-spectral images, in a high dynamic range multi-wavelength image data. The apparatus captures the images through an optical path sharing one or more optical elements and a detection unit. The captured images are processed by a computing device associated with the apparatus for either OCT or hyper-spectral imaging.

Abstract: Embodiments of the present disclosure provide a photocoagulation device and a method to produce a light beam of a predefined wavelength using the photocoagulation device. The device comprises at least one light source, non-imaging light collimator (NILC), at least one first and second condenser, a ball lens and at least one galvo-mirror. The light source is one of light emitting diode (LED) and organic LED (OLED), which emits light of a predefined wavelength. The NILC collimates the light emitted by the at least one light source, the at least one first condenser produces a focused light beam using the collimated light. The at least one second condenser produces light spots, with a diameter in terms of microns, using the focused light beam from the at least one first condenser. The ball lens collimates the light spots, which is steered by the galvo-mirror to focus on a target area.
