The unit optical system is an upright unit-magnification optical system.

HSB unit for right-hand traffic

The optical signal-to-noise ratio is read from the intersecting point of the first straight line with the second straight line.

One or more motors advance and retract the optics stage, move the optics stage left and right, and/or move the optics stage up and down.

The diagonal straight line represents perfect agreement.

The diffractive index of the first diffractive optical member and that of the second diffractive optical member are different from each other at d line.

The optical center of the diverging lens (22), the optical center of the condensing lens (32) and the light source (10) are in the same straight line.

A light scanning system for moving a light beam (64) across a straight surface (42).

The polynomial is added to the optical line up to the point where the selected ray is deflected.

The RCW molding portion is formed adjacent a peripheral edge of the optical insert.

The central portion contains at least one optical fiber and the left and right portions contain electrical conductors.
