Meeting Your Needs
Back in 1985, we found that commercially available mechanical stages were simply unable to deliver the precision and durability necessary for high-precision applications. So we set out to design components and systems to meet these needs. Over the years, we developed several unique and efficient designs which evolved into many of our standard product lines.

Your systems benefit from our experience. Because we've designed numerous systems and subassemblies to varying degrees of stage size, accuracy, travel, resolution, and more, we're able to pull from our modular product offerings to quickly adapt or generate new designs to meet your needs.

High-precision products require a specialized manufacturing process under tightly controlled conditions. That's why we manufacture our stages in-house. By recently tripling our computerized machine processing equipment,we've fine-tuned this process to meet a balance of thorough "built in" quality with cost-controlled manufacturing efficiency.

Implementing quality inspection of materials before, throughout, and after manufacture insures your system's optimum performance. Systems are subject to the final stringent inspection of our quality assurance group before they go out the door to you. JMAR-PSI's processes are fully ISO 9001 certified.

  • Mask inspection

Now - Ultra-Precision In A Compact X-Y Stage Package!

Introducing the JMAR-PSI Ultra-SlimLine™ Stage
JMAR-PSI now offers the Ultra-SlimLine™ (USL) Stage. Small on footprint and big on precision, the USL offers a choice of 8 x 8 or 12 x 12 inches of travel. Each axis has motor, limit, and encoder cabled to a single connector bulkhead, and has the unique feature of completely enclosed motors and internal cabling. It incorporates a vacuum-line system throughout the stage. Designed with 3mm crossed roller bearing linear guides.

The USL offers 7075-T6 construction and is NEMA 17 servo or stepper motor capable. Uses 1/2 inch precision universal thread lead-screws capable of right or left-hand configurations. This low-profile stage is only 3.23 inches high and this height advantage is ideal in a host of applications. Provides the accuracy and reliability normally found in higher-profile models.

Ultra Slim Line
Positional accuracy: +/- 5 µm over total travel
Positional repeatability: +/- 1.5 µm
Flatness of travel: +/- 2 µm 8 x 8 inch
+/- 3 µm 12 x 12 inch
Orthogonality: +/- 2 arc. seconds 8 x 8 inch
+/- 3 arc. seconds 12 x 12 inch


High-precision Positioning Stage and Motion Control!
Linear Servo Motor Stage
The new JMAR Precision Linear Servo Motor (LSM) Stage is a low profile, precision-grade stage with high rigidity yet lightweight structure. The LSM Stage is a robust, industrialized, direct-drive linear positioning system featuring brushless linear servo motor drive for high dynamic performance. The LSM Stage addresses demanding requirements for fast move-and-settle motion profiles as well as smooth velocity control. A compact aluminum slide is guided via low friction recirculating bearings.

  • Engineered and manufactured for high reliability
  • Wide array of applications
  • High repeatability and accuracy
  • Low/no maintenance

Dynamic Characteristics

Accuracy of Mean Position <+/- 5 µmeter
Bidirectional Repeatability +/- 1 encoder count
Velocity 400-2000 mm/second
Acceleration .08-3 g's
Settling Time <.025 second - increased throughput

Advantages over Standard Stages

  • Fewer moving parts means higher reliability
  • Lower profile for fitting into smaller spaces
  • Direct linear motion without mechanical transmission devices
  • Provides linear thrust as opposed to torque force
  • No backlash from ballscrews or gears and no slippage from belts

Typical Applications

  • Semiconductor/disk drive
  • Manufacturing/machining
  • Labeling/packaging
  • Coordinate measuring
  • Laser processing
  • Medical
