Vaughan, Ontario, Canada — MicroE Systems has recently released it’s the new Optical Positioning Sensor (OPS™) Series, which delivers high performance and advanced positioning system features. The OPS™ sensor is equipped with MicroE’s patented optical design and features built-in interpolation and AGC ensuring optimal performance and reliability.

OPS™ can be configured with optical limits to reduce cabling and works with MicroE’s cut-to-length linear tape, cost-effective linear glass, and rotary glass scales, minimizing total cost of ownership.

The DS-25 is well suited to demanding applications such as: aerospace, medical, instrumentation, automation, etc.

Multiple mounting configurations are available and intuitive tools make installation and commissioning fast and simple. A dual-purpose LED in the sensor simplifies installation and provides real time indication of system health.:

OPS’s low cyclical error (up to +/-25nm) enables high positioning accuracy (up to +/-3um/m) and smooth velocity control. With linear resolutions of 1µm, 0.5µm, 0.1µm and 50µm, and rotary resolutions of 163k CPR to 3.3M CPR, OPS™ fits many different applications.

Sunnyvale, CA, — Developed for precision optical positioning applications the LFA-1012 Motion Control Linear Focus Actuator features a patented zero-translation tangential flexure for high speed travel. The clear aperture, 10 mm (0.394 in.) stroke length and standard 12 mm optics mount (or an optional DIN mount for use on microscopes) make this linear focus actuator ideal for: Optical focusing, scanning, interferometry, surface structure analysis, disk drive testing, autofocus systems, confocal microscopy, biotechnology, and semiconductor test equipment.

A frictionless, closed loop, non-contact sub-micron resolution linear displacement sensor having high bandwidth and low noise assures high responsiveness and ultra precision. Positioning resolution of the LFA-1012 actuator is 150 nm, repeatability is 200 nm (short term) and 50 ppm/1000 hr. (long term) with 2.2 lbs. continuous and 3.5 lbs. peak force.

span style=”font-family: verdana,helvetica,arial; font-size: small;”>The low inertia, zero stiction/friction, ± 12 VDC to ± 24 VDC @1 amp, voice coil motor of the Linear Focus Actuator has very low electrical noise, is clean room compatible, and can be operated in any orientation. Mounting holes on various surfaces makes mounting easy in new or existing applications.

The corresponding SCA814 Linear Servo Controller is also available from Equipment Solutions. It is a high performance single axis DC motor controller and amplifier that was developed for applications requiring high temporal and spatial servo precision.
