Request InfoHeidenhain CorporationHEIDENHAIN is proud to introduce a new high-accuracy motion feedback encoder that can now be used for absolute positioning in machines in the semiconductor, metrology, and robotic industries. This new LIC 3100 absolute kit encoder is an additional offering that fits between HEIDENHAIN’s already successful LIC 4100 and 2100 series. It is expected to be of special interest to users since it is also especially tolerant to contamination and has very loose mounting tolerances. It is important to note that the graduation of the new LIC 3100 encoder is carried by a sturdy stainless-steel...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 8/6/2021Linear Voice Coil StageThe VCDS-051-032-01-B1-30 linear voice coil stage from Moticont features high speed, high acceleration/deceleration, zero backlash, smooth motion, precise positioning of 30 μm, high reliability,...Photonics.com 7/7/2021Open-aperture Voice Coil Linear MotorThe HVCM-025-038-003-02 open-aperture voice coil linear motor from Moticont is a 1-in. body diameter servo device.

Mechanical noise, for example, can obscure high-resolution images and affect the quality of nanotechnology processes. Fortunately, vibration can be controlled through proper experimentation, process design, and the use of specialized equipment.In general, there are three common approaches to reducing mechanical excitation of photonic systems. The first is identifying the sources of vibration and implementing ways to eliminate or reduce...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookNanopositioning: A Step Ahead: It is almost a cliché among students of creativity that innovation occurs at the intersection of fields. Since nanopositioning is a discipline that has enabled swiftly evolving application arenas as diverse as materials science, genomics, photonics, defense, biophysics, and semiconductors, it’s unsurprising that its pace of innovation is nothing short of blistering in recent years.By its original definition, a nanopositioning device is a mechanism capable of repeatedly delivering motion in increments as small as one nanometer.
