上述楔形体的三个侧面是前面提到的锥形的组成部分，于是，当相应的锥形轴线或者相应的三维直角坐标系的半轴转动的时候，上述楔形体可以在其锥形的内表面转动。

Theoretical analyses show that the BRF has the maximum tuning rate when the optic axis is located on the cone with its symmetric axis being on the refracted ray and apex of 45°; and the rejection of unwanted wavelength of BRF becomes the maximum when the optic axis is in the plane which contains the refracted ray and makes the angle of 45° or 135° with respect to the incident plane.

分析表明当晶片光轴处在以折射光线为轴线、顶角为45°的圆锥面上时，双折射调谐器具有最快的波长调谐速率；当光轴位于过折射光线并与入射面成45°或135°的平面内时，调谐器抑制非所需波长的能力最强。
