关于调节分光计平行光管,以下说法错误的是: As for the adjustment of the collimator of spectrometer, which operation below is incorrect
A.为使通过平行光管的光线成为平行光,应将平行光管的狭缝位于平行光管物镜的焦平面上。 In order to get parallel light after the light passing through the collimator, the slit of the collimator should be located on the focal plane of the collimator objective len
B.调节时,先取下平面镜,用钠光灯照亮狭缝,用已调好的望远镜作标准,使望远镜正对着平行光管,调节狭缝装置的锁紧螺丝,前后移动光管的套管,直到在望远镜中清晰地看到狭缝的像,这时表明狭缝已位于平行光管物镜的焦平面上,从平行光管发出的光束为平行光束,旋紧狭缝的锁紧螺丝,固定狭缝 For adjustment, take down the plane mirror firstly, illuminate the slit with sodium lam
参考答案和解析
发出平行光的部件
