Description

A new type of slit light illumination device

technical field

The invention relates to an illuminating device, in particular to a novel slit light illuminating device. the

Background technique

The existing slit light illumination system of medical optical instruments (Fig. 1) needs to first use the light source (7) to illuminate the slit plate (10) through the second condenser lens group (8) and filter group (9) to generate slit light, and then The second projection lens group (11) projects onto the tissue to be observed to form an optical section. In this method, the color change of the slit light needs to be realized by switching different filters in the filter lens group; the brightness of the slit light is controlled by the brightness change of the light source; Relative position changes to adjust. From the actual application situation, this method has the following disadvantages: complex structure, difficult design and processing, and poor assembly process. the

1. The structure is complex. The adjustment of the slit light characteristics of this method needs to be realized through three different approaches. the

2. It is difficult to design and process. This method needs to design a precise mechanical structure to realize the adjustment of the color, length, width, and azimuth of the slit light, and the design and processing are difficult. the

3. Poor assembly process. In the assembly process of this method, it takes a lot of time to repeatedly adjust the parts to obtain the ideal slit light lighting effect, and the assembly efficiency is low. the
