Nanofocusing Objective Stage, Vacuum Compatible, 250 µm, Strain-gauge
Model: NPO250SGV6
Product Series Overview
Nanofocusing Objective Lens MountsThe NPO250SGV6 Vacuum Compatible Objective Nano-Focusing Objective Stage is a high-speed, piezoelectric-driven device that provides fast focusing and scanning over 250 µm travel. It is compatible with most microscopes and objective lenses. Typical applications include surface profilometry, high-resolution imaging, auto-focusing, scanning interferometry, and confocal microscopy. NPO stages feature highly reliable, multi-layer, low-voltage, piezoelectric transducer (PZT) stacks, which are optimized for high-duty cycle operations. Image shifts and tilt are minimized by an FEA-modeled and precision EDM-cut parallelogram, solid-state flexure that ensures perfectly straight motion and also provides the highest possible stiffness for superior focus stability, higher frequency auto-focusing, shorter settling times and faster scans. NPO stages are maintenance-free and are not subject to wear.
This closed-loop version features a high resolution strain-gauge position sensor for highly accurate and repeatable motion and compensates for actuator creep. For highest position stability and highest temperature-insensitive performance, the sensors are assembled in a full Wheatstone bridge design. The closed-loop devices can be operated in open or closed-loop control. The NPO NanoFocusing stages mount between the turret and the microscope objective and add only 11.5 mm to the optical path length. It can be used for standard and inverted microscopes. The standard thread size is W0.8 x 1/36 inch and is compatible with all Newport objective lenses. Vacuum compatible to 10-6 Torr.
Use with the NPC3SG Nanopositioning Amplifier.
