New URS precision rotation stages from Newport

Newport Corporation (www.newport.com), a global leader in photonic and laser solutions that “Make, Manage and Measure Light”, is proud to announce the release of the URS50BPP and the URS50BCC precision rotation stages that feature 360°, continuous motion. These new stages have the smallest footprint of 50mm in size, and are offered in very affordable price, while maintaining the high performance of URS motion product family from Newport.

The URS50BPP and the URS50BCC provide very low wobble and backlash-free, continuous rotation with extremely high MTBF of up to 20,000. Competitively priced, the high-performing rotation stages feature large stage performance in a very small package. The two stages also offer exceptional 6µm eccentricity and easy integration.

The URS50B’s feature a one of a kind, two-part bearing design with pre-tempered bearings and steel gears to ensure long-life motion positioning and precision. The URS50BCC, the DC-motor version with embedded index pulse for precision homing, is best suited for demanding applications that need bi-directional positioning.

The economical URSBPP stepper motor version is ideal for less demanding, yet precision rotation applications. Each URS50B has a cable URS50B for plug-and-play compatibility with XPS, SMC and ESP.

IP66-Rated Direct-Drive Rotary Stages from Aerotech

The ASRT is an IP66-rated, direct-drive, sealed rotary stage that provides precise angular positioning in hostile environments where dirt, dust, cutting fluids and fluid jets are present. Applications range from industrial machining automation to precision sensor positioning in hostile environments, and the ASRT is also an effective solution for precise rotary motion in product environmental test and range tracking applications.

The ASRT is offered with either high accuracy encoder or magnetic encoder feedback. Unlimited travel is standard, with an optional limited travel model also available. Three different models cover a wide range of load and torque requirements.

The ASRT series uses Aerotech’s brushless, slotless motor that has no brushes to wear, no gear trains to maintain, and high acceleration and high speeds. The low inertia and zero backlash make the ASRT the ideal solution for applications requiring frequent directional changes. In addition, Aerotech manufactures a wide range of servo amplifiers and advanced controllers to provide a complete, integrated package.

Dual large-diameter bearings are used to maximize performance with respect to tilt error motion (3 arc sec), moment stiffness, and repeatability (1 arc sec). The large diameter bearings permit large payloads (up to 175 kg) without compromising performance.

Maximum rotary speeds are from 100 to 200 rpm. The ASRT includes an electrically grounded shaft and housing to protect against electrical shock and eliminate RF re-radiation, and housing grounding points are included. Circular sealed connectors are standard, while options include desiccant cartridge, air purge, and mounting flange accessory.

A polymer-based paint on the housing and a hard-coated tabletop prevent corrosion. The stage has optional brown, green, grey, black, and white paint colors. Standard operating temperature is 0 to 70°C. Operation below freezing requires the optional air-purge and desiccant, with air-purged stages operational from -20 to 70°C.

Rotary Stage features Compact Package and Accurate Positioning

RTHM-100 compact rotation stages are designed to rotate optical components and small tooling in the confined spaces of the manufacturing processes for fiber optical components and semiconductor devices, fiber optic alignment, laser diode research, bio-medical applications and inspection systems.

The lightweight design feature low 32 mm profile height and incorporates anodized aluminum body with pre-loaded ball bearings with run-outs of 5 microns. This proprietary bearing design provides smooth rotation with minimal wobble.

A precision ground worm gear produces consistent driving torque to the rotor and eliminates variations in the motor current.

RTHM-100 stages feature an angular resolution 0.1 arc-sec, which may be achieved with either DC Servo or stepper motor controls.

The stages are equipped with a reference home sensor. RTHM-100 stages can run in continuous or start/stop rotation modes and mounted horizontally or vertically.

These stages feature zero backlash, large 50 mm center aperture and can rotate loads of 20 kg over unlimited rotation angle.

High Speed Piezomotor Rotary Stage from PI

San Francisco, CA — PI (Physik Instrumente) L.P. introduces a new ultra-low profile (0.6”), direct-driven, high-speed rotary stage based on its proprietary PILine® piezomotor drive technology at this year’s SPIE Photonics West conference. The new ultra-low profile (0.6”), direct-driven, high-speed rotary stage is based on PI’s proprietary PILine® piezomotor drive technology.

The M-660 stage reaches top speeds of 720 degrees/sec. and resolution to 40 µrad (8 arcsec). Its self-locking ceramic drive holds the position steady at rest, with no energy consumption and heat generation. A directly coupled precision optical encoder provides phase lag-free, backlash-free feedback to the servo controller.

Multi-axis Modular Assembly from Steinmeyer

BURLINGTON, MA — Steinmeyer, Inc. announced a new multi-axis modular assembly designed specifically for 3D target positioning and alignment. Typical applications include R&D and scientific uses such as synchrotrons. For example, the new system is ideal for beam positioning and sample manipulation.

The assembly utilizes the compact Steinmeyer type MT130 linear stage together with a type DT110 rotary stage to yield two to four axes of motion – XY, X-rotary, XYZ, XY-rotary, or XYZ-rotary. Each of the MT130 stages offers 50 mm stroke with standard flatness/straightness/repeatibility of +/- 1 micron. Maximum speed is 50 mm/sec. The linear stage is driven by a miniature Steinmeyer precision ball screw and includes crossed roller bearings, limit switches, dc servomotor and rotary encoder.

The DT110 rotary stage has a +/- 1 micron flatness of rotation and repeatability of +/- 0.002 degrees. Maximum speed is 200 degrees per second. Precision brackets are used, where necessary, to easily connect the various stages to achieve the final multi-axis configuration. A compact 2 to 4-axis DC-Controller is available with “plug- and play” characteristics, including LabVIEW® compatibility. Standard options include joystick control and direct reading scales for higher accuracy.
