Problems solved by technology

However, the slit light starts from the light source and needs to go through a relatively complicated optical path to finally form a usable beam. Not only is the structure complex, the assembly is difficult, the production cost is high, and the optical performance is not stable enough, it needs to be further improved.

Abstract

The invention discloses a slit light generating assembly and a hand-held slit lamp microscope. The slit light generating assembly comprises a lens cone, a light source lens, a slit sheet and an LED lamp circuit board; the slit sheet is arranged in the lens cone along the cross section direction, the inner wall of the lens cone is provided with a slit sheet supporting part positioned at the front side of the slit sheet along the light path direction; the LED lamp circuit board is provided with an LED lamp positioned at the rear side of the slit sheet along the light path direction, and a slit sheet pressing ring is arranged between the slit sheet and the LED lamp circuit board; and the rear end of the lens cone is provided with a lens cone rear end cover in sleeving connection, and the slitsheet, the slit sheet pressing ring and the LED lamp circuit board are sequentially positioned between the lens cone rear end cover and the slit sheet supporting part along the light path direction.The slit light generating assembly provided by the invention is simple in structure, easy to assemble, stable in light performance and convenient to use, and not only can reduce the production cost, and is beneficial to improving inspection efficiency and inspection accuracy.

Description

technical field [0001] The invention relates to the technical field of eye disease inspection equipment, in particular to a slit light generating component of a slit lamp microscope used in ophthalmic inspection. The present invention also relates to a hand-held slit lamp microscope provided with the slit light generating assembly. Background technique [0002] The slit lamp microscope is an essential and important instrument for ophthalmic examination. In use, the light passes through a slit to illuminate the eyes. Because it is a narrow slit light source, it is called "light knife". [0003] The "light knife" is irradiated on the eye to form an optical section, and the health status of each part of the eye can be observed. The principle is to use the "Tyndall phenomenon" of the British physicist Tyndall, that is, when a beam of light passes through the colloid , From the vertical direction of the incident light, a bright "path" in the colloid can be observed. This phenom...
