Volume Discount

High-accuracy goniometer stage with excellent operability that uses a crossed roller for the travel guide and a worm gear for the feed mechanism.
It is ideal for frequent operations.
・ High accuracy
High accuracy of 0.01 mm or less of rotation center deflection accuracy.
· Wide variations
In addition to the vernier scale (minimum reading 0.1°) on the side, the clamp position can be selected from L and R according to the installation location.
"Applications" · Precision adjustment of cameras, microscopes, sensors, and optical parts
・ For positioning during production, assembly and inspection processes related to semiconductors and measuring instruments
