MEMS Inclinometer

The PTAM27L series MEMS-based inclinometer from ASM Sensors (Elmhurst, NY) is designed for single- and dual-axis tilt angle measurements. For single-axis versions, measurement ranges span from ±15° to ±180°, in increments of 15°. For dual-axis versions, the measurement ranges span from ±15° to ±60°, in increments of 15°. The inclinometer is an extension of the POSITILT® MEMS-based inclinometers. The wear-free sensing technology provides shock resistance. The housing is rated IP64 and has a height of 10 mm. The device offers 0.1° resolution and ±1° linearity.

Vertical Lift Stage

Aerotech (Pittsburgh, PA) offers the ANT 130-5-V linear motor-driven wedge-style vertical lift stage that provides in-position stability for nanopositioning applications. It offers travel up to 5 mm and is a precision stage designed for standalone use, or it can be integrated with other stages for a multiaxis nanopositioning system. The stage utilizes directdrive technology, as well as anti-creep crossed-roller bearings. The direct-drive technology is non-cogging, non-contact, high-speed, and high-resolution. Applications include fiber alignment, optical delay element actuation, sensor testing, and scanning processes that require stable, repeatable motion. The stage has universal mounting and tabletop patterns for system integration.
