在以往的一些文献中曾叙述了λ/4波片的制作方法,由于选用了发散光源做参考光源,所以限制了精确制作和测量λ/4片的准确性,我们用激光作为光源制作出了较高精度的λ/4片。 一、λ/4片的制作和测量 我们是选用云母片作为制作λ/4片的原料,因为云母片比较容易剖开到所需要的厚度。先把市场上采购来的大小不一的云母片,用锐利的剪刀剪成大小一致的长方形片(约50×40),然后,用清洁的针头从云母片的边缘伸进去,留出一条缝,加入几滴酒
In the past some documents have described the production of λ / 4 wave plate, the use of a divergent light source as a reference light source, thus limiting the precise manufacture and measurement of λ / 4 piece accuracy, we use the laser as a light source to produce a High-precision λ / 4 piece. First, the production and measurement of λ / 4 We use mica as the raw material for making λ / 4, because mica is easier to cut to the desired thickness. First on the market to buy different sizes of mica, with sharp scissors cut into rectangular pieces of uniform size (about 50 × 40), and then, with a clean needle from the edge of the mica into, leaving a seam , Add a few drops of wine
