Manual Adjuster, High Precision, 8.0 mm Coarse Travel, 0.3 mm Fine Travel

DS-4F adjuster has the industry-standard 9.5-mm mounting interface making it both interchangeable with other micrometers and compatible with almost all Newport stages and mounts.

The DS-4F high precision adjuster is based on a mechanical lever system that provides exceptional 20 nm adjustment sensitivity. Its high-resolution and value make this adjuster a suitable alternative for a differential micrometer in cases where a direct position readout is not required. To activate the fine adjustment, the coarse adjustment needs to be locked in place with the thumbscrew.
