    • A hand-held examination device for imaging the eye (106) comprises a user interface (108), infrared source (150) and visible light source (152). The infrared source (150) illuminates the eye (106) with infrared radiation, the examination device forms an image of the eye (106) while illuminated by infrared radiation, and the display shows the eye (106) illuminated by infrared radiation. The user interface (108) receives from the user a signal for generating an image. The visible light source (152) is switched on in a predefined manner in response to the received user signal for generating the image. The examination device generates at least one image of the eye (106) by using visible light in response to the received user signal for generating the image.
    • 用于对眼睛进行成像的手持检查装置(106)包括用户界面(108),红外源(150)和可见光源(152)。 红外源(150)用红外线照射眼睛(106),检查装置在被红外辐射照射的同时形成眼睛(106)的图像,并且显示器显示由红外辐射照射的眼睛(106)。 用户界面(108)从用户接收用于生成图像的信号。 响应于接收到的用于生成图像的用户信号,以预定的方式接通可见光源(152)。 检查装置响应于接收到的用于生成图像的用户信号,通过使用可见光来生成眼睛(106)的至少一个图像。

    • Light from an exit pupil (112) of an illumination unit (100) is directed to a beam splitter (102) which directs the light to an objective (104). The retina (128) is illuminated, if a real image of the exit pupil (112) of the illumination unit (100) and a real image of an entrance pupil (114) of a camera unit (106) are formable in a position ranging from the corne a (120) to the backside (126) of the crystalline lens (124) with the light. The objective (104) forms a real intermediate image (130) of the retina (128) between the objective (104) and the camera unit (106). The beam splitter (102) directs the light from the retina (128) to the camera unit (106), while causing the path (134) of the illumination and the path (132) of the imaging to deviate for non-overlapping images of the exit pupil (112) and the entrance pupil (114) in the crystalline lens (124). A relay lens system (138) forms a real image of the intermediate image (130) on a detecting component (136) with the light reflected from the retina (128) for transforming the image into an electric form to be shown on a screen (150).
