Optical axis deviation

WebThe optical axis of a lens is defined by the optical surfaces and is the line that connects the centers of curvature of the surfaces. To test for centration, a lens is placed into a cup upon which pressure is applied. WebOct 21, 2013 · OAPs are a common optical component available off-the-shelf from optical manufactures including Edmund Optics [1], Thorlabs [ 2], and Newport [3]. They are specified by their size, reflected focal length, and angular deviation. They are most commonly available with a 90° deviation, but are also available with other angles of deviation.
