The forward rectangular panel can either lie flat or propped up, with a small object, for the proper reflectionAngle as required.
远期矩形板既可以平躺或支撑，一个小对象，根据需要适当的反射角度。

By means of intermediate image immersing technology, the present invention has increased reflectionAngle, reduced straight collimator core diameter and shortened straight collimator length.
本发明是借助中间像浸没的技术，增大反射角、减小直光管芯径，缩短直光管的长度。
