Description

тапризму, отличающеес  тем, что, с целью повышени  чувствительности, точности контрол  вогнутых и выпуклых параболоидов, гиперболоидов , а также вогнутых эллипсоидов, очо снабжено эталонной параболической и вспомогательной плоской отражающими поверхност ми , расположенными на оптической оси контролируемой поверхности так, что точки фокуса этих поверхностей совмещены, и дополнительными пентапризма ми, расноложенными по ходу пучка симметрично относительно той же оси.Capriciousness, characterized in that, in order to increase the sensitivity, accuracy of control of concave and convex paraboloids, hyperboloids, and also concave ellipsoids, it is very often equipped with a reference parabolic and auxiliary flat reflecting surfaces located on the optical axis of the test surface so that the focus points of these surfaces combined, and additional pentaprisms, located along the beam symmetrically about the same axis.
