Optical axis direction
WebDec 1, 2014 · In principle, the mirror M1 can be placed at an arbitrary angle between 0° and 45° and be rotated around the optical axis of the remote objective to achieve arbitrary … WebFor this reason, the direction perpendicular to the circular cross section is called an optic axis. Uniaxial crystals have one optic axis. Biaxial crystals have two optic axes. • The acute angle between the two optic axes in biaxial crystals is called the indicatrix 2V.
