A tip-tilt stage is the core component of this positioning system. The arrangement of the three turrets allows a roll and pitch motion of the top plate in the range of ±13° for Θx, ±15° for Θy and a linear translation in the Z direction of 10 mm. The top plate also includes a slot to mount a SR-4011 rotation stage to add a fourth degree of freedom to the setup. The bottom plate on the contrary allows a direct mounting to a breadboard or a XY platform consisting of two CLS-92 linear translation stages. The later possibility yields to a 5D or together with the SR-4011 to a 6D positioning system.
Values for rotational travel are given for a Pivot point at the surface of the top plate.
