MDE227 - Long Travel Piezo Adjuster - 100 µm piezo travel

Long Travel (100 µm) Piezo Adjuster   

MDE227   

• 100 µm travel
• 50 nm resolution

This Long Travel Piezo Adjuster is for applications requiring an increased range of high precision adjustment. The MDE227 gives 100 µm of piezo travel with 50 nm resolution by means of a lever mechanism to amplify the extension of a 40 µm piezo stack. It also incorporates a 12 mm sleeve matched to the Elliot Gold™ series flexure stage.

An integral hex adjuster is built into the coarse drive. This adjuster protrudes significantly from the flexure stage body, so finger pressure effects during manual adjustment can cause cross-talk between axes. Adjustment using a ball-headed hex key avoids these effects and the adjuster is driven in the intended axis only.
