五角棱镜penta prism
penta prism can deviate an incident beam without inverting orreversing to 90°. the deviation angle of 90° is a constantangle that applies to all rays transmitted by the useful aperture,regardless of the incidence angle of the beam.
五角棱镜可以在不反相或倒转的情况下将入射光偏离90°角。偏离的90°角是固定的角度，适用于有效孔径内的传播光线，并且与光束的入射角无关。
