Fine-pitch Screw Adjusters / FPSAN

This is the successor model to FPSA series. It is scheduled to be available for sale around January 2024.

These adjustors are direct replacements for micrometers used on OptoSigma stages.
The knobless design saves space and prevents inadvertent operation.
The FPSAN series has dedicated set screw section and a dedicated knob (optional) that eliminates the need for tools.
The knobs can be installed when they are used and removed when they are not required, which improves the operability and efficiency of manual stages and maintenance work.

The screw bushing can be lock with the clamp screw.
The clamping is carried out with a tip resin set screw, which does not damage the threads with the spindle.
Since the flat-type tip is compatible with OptoSigma manual stages and holders, the change of specifications is available. And R-type with a spherical tip is also available.
