Open Optical Encoders
-
An optical encoder is an electromechanical device which produces an electrical signal output proportional to the linear displacement of a linear guide or the angular position of an input shaft.Open encoders are exposed and feature no external integrated enclosure. The advantages of open optical encoders include the effective elimination of backlash, shaft wind-up (torsion) and other mechanical hysteresis errors.A rotary open optical encoder consists of a position measurement readhead and an accurate rotary scale marked either on the periphery of a ring or on the face of a disc.The readhead measures position by optically sensing the regularly-spaced scale markings and outputs this information as an analogue or digital signal.The signal is subsequently converted into a position reading by a digital readout (DRO) or motion controller.

Optical Delay
ODL
-
The Peregrine Optical Delay Line (ODL) provides an exceptional combination of precision, speed, and optical stability at a low price. It is ideally suited for pump-probe experiments and autocorrelation measurements (both interferometric and intensity methods). Advanced voice coil technology allows the ODL to be positioned anywhere in its travel range to within 150 nm. That’s 1 fs for a double-pass configuration. The response time is as short as 1 ms. Our 1-cm-travel ODL is interferometrically stable (measured using a 650 nm laser). No backlash, no hysteresis and no drive trains to wear out as with stepper motors. It’s convenient–the ODL can be positioned using digital commands, an analog voltage or a combination of the two. Two 16-bit on-board analog-to-digital converters simplify data collection. Digital inputs and outputs allow master or slave clocking. An executable Windows application is provided to get you up and running in minutes. In addition, DLLs and LabVIEW Vis for integration into your software are also included.

Power Amplifier
5241
-
The Model 5241 is a voltage-controlled power amplifier designed exclusively for Magtrol's Model HD-825 Hysteresis Dynamometer. Because of its double braking system, the HD-825 requires more than 4 amps of power in order to reach full torque. The 5241 (which can provide up to 5 amps of output current) is necessary in order to amplify the power between a 6200 or DSP6001 Controller (which both have a maximum current output of 1 amp) and the HD-825 Dynamometer.

High-Dynamics PIMag Linear Stage
V-522 • V-524 • V-528
-
Physik Instrumente GmbH & Co. KG
Reference-class linear stage. Linear positioning stages with magnetic direct drives largely dispense with mechanical components in the drivetrain and the drive force acts directly on the motion platform. Together with precision bearings, a high travel accuracy and longer lifetime is achieved. The linear positioning stages are particularly suitable for scanning applications. PIMag® Voice Coil. Voice coil drives consist of 2 essential components: A permanent magnet and a coil, which is located in the air gap of the magnetic field. When current flows through the coil, it moves in the magnetic field of the permanent magnet. The direction of motion depends on the polarity. Thanks to their low weight and friction-free drive principle, voice coil drives are particularly suitable for applications, which require high dynamics and high velocities at limited travel ranges. High scan frequencies and precision positioning are also possible with these drives, because they are free of the effects of hysteresis.

Absolute Optical Inclinometer
A2T
-
The A2T is a single axis, digital gravity angle sensor. The A2T serves as a full 360 range absolute tilt sensing programmable level with either digital or analog output. Internally, a rotary bar coded disk is mounted to a weighted gravity driven wheel. A micro-controller strobes an LED to transfer the bar code image onto an optical linear array, then decodes the position every 2 mSec. Magnetic damping provides fast response and settling time while virtually eliminating overshoot and oscillations. An internal EEPROM stores field programmable parameters such as resolution, zero position, direction swap, and mode. This second generation design virtually eliminates the primary accuracy limitation of first generation inclinometers, which is sitation (hysteresis).
