How to Interpret 6‑DoF / 6 Axes (XYZαβθ) in Our Products
The coordinate axes used in our products are defined as follows.
X-axis: Parallel to the optical axis (optical axis direction). Often used to refer to Forward & Backward movement along the optical axis.
Y-axis: Equivalent to Left & Right when the X-axis taken as Forward & Backward. Perpendicular to the X-axis and Z-axis.
Z-axis: Up & Down.
Alpha-axis: Represents the rotational degree of freedom around the X axis (Roll).
Beta-axis : Represents the rotational degree of freedom around the Y axis (Tip).
Theta-axis: Represents the rotational degree of freedom around the Z axis (Tilt).
The six axes above correspond to the six degrees of freedom (6DoF) of movement that a rigid body can have in three dimensions.
Please note that optical element mounts from other companies may have the Z axis aligned with the optical axis, so the name of the rotation axis may differ.

【Note】
・△△ can be a 2-3 digit number.
・”*” means that the height (Z position) can be adjusted at the post (pole).
It is not included in the number of axes.

【Note】
・△△ can be a 2-3 digit number.
・The X-Axis Stage becomes a Y-Axis Stage by rotating the installation direction (Theta angle) by 90°.
・The XZ-Axis Stage becomes a YZ-Axis Stage by rotating the installation direction (Theta angle) by 90°.
・The Goniometer Stage (GM Series) and Tilt Stage (TS-60S, TSP-1016) can be adjusted to the Beta-Axis by rotating the installation direction (Theta angle) by 90°.
