GCM-080904M is a Vertical Drive Kinematic Lens/Mirror Holder, which provides two-axis tilting adjustment by means of two high precision screws on the top of the holder. It can be used in minimizes space along the optical axis, which can avoid obstructing the beam path during the adjustment. Each tilting adjustment has a range of ±2.5° (Θx, Θy) rotations. There is also a tapped hole of M4 for adapting our other products.
