目前使用的带状光检影镜,在性能上明显优于一般的点状光检影镜,特别在测定散光度数及轴位上,更有其独到之处。因此,在美国早已被广泛采用。我国现已逐渐推广。笔者在使用过程中,发现此种仪器还有一大特点,据此设计了一种新型的散光轴位指示式带状光检影镜。其优点是:能快速、精确地测定出受检眼的散光轴位,并通过仪器上的刻度指示出来,省时,效率高等。现已申请专利(申请号:912037105)。下面加以介绍。一、结构与性能具体设计是在现有的带状光检影镜上加厚头部活动套管下端(A),以便增开一个Φ2mm 的固定螺丝孔,对应在凸透镜座(B)外壁开一圆周小槽(C),使螺丝(D)很好固定在小槽内,
The current use of strip light mirror, the performance is obviously better than the general point light mirror, especially in the determination of astigmatism and axial position, more unique. Therefore, it has long been widely adopted in the United States. My country is now gradually promoted. In the course of using the author, I found that there is a large feature of this instrument, and accordingly designed a new type of axial astigmatism strip photographic mirror. Its advantages are: can quickly and accurately determine the astigmatism axis of the subject eye, and through the instrument on the scale indication, save time, high efficiency. Has applied for a patent (application number: 912037105). Introduced below. First, the structure and performance Specific design is to strip the lower end of the active sleeve (A) on the existing strip-shaped optical inspection mirror in order to increase a fixed screw hole Φ2mm, corresponding to the outer wall of the convex lens holder (B) open A small circumferential groove (C), so that the screw (D) is well fixed in the small groove,
