High-resolution microscopy offers researchers and clinicians a powerful analytical tool to help uncover a variety of biological phenomena and processes. However, instruments of this type require a...

The CONEX-AGAP application is designed to control a single piezo motor positioner. For customer configurations using several positioners, it is necessary to launch several instances of the applet in...

The production of low-loss interconnections between two or more optical components in a fiber optic assembly can be tedious and time consuming. Interfacing optical fibers to other fibers or to other...

The function of a motion device, such as a stage, is to generate a desired motion in an ideal trajectory. Furthermore, the device must be able to reliably and repeatably reach a specified target...

This technical note describes the fundamentals of vibration and how these concepts relate to measurable parameters such as compliance and maximum relative motion....

Newport Hexapods are 6-axis parallel kinematic positioners engineered for exceptional stiffness and load capacity in compact designs with precision moves on the sub-micron scale. With 6 Degrees of...

The micro-LED (Light Emitting Diode) is the latest in the LED evolution. A standard LED is approximately 250 microns, a mini-LED is approximately 100 microns, and the term micro-LED (also known as...

Backlash: Non-responsiveness on reversal of input. For example, a simple motorizer with motor-mounted encoder might exhibit several microns of position display change on reversal before its output...

The function of a translation stage is to constrain motion to a desired direction. For a linear stage, the desired motion is along an ideal straight line. Any motion in constrained directions will...

The function of a linear or rotary stage is to generate a desired motion in an ideal trajectory. Factors like friction between moving parts, quality of guides or bending induced by moving loads, often...

An automated motion control system consist of three main components: a motion controller, a motor driver or amplifier, and a motion device. The primary purpose of a motion controller is to control the...

Common motion systems use three types of control methods. They are position control, velocity control and torque control. The majority of Newport’s motion systems use position control. This type...

Open loop refers to a control technique that does not measure and act upon the output of the system. Most piezoelectric systems and inexpensive micrometer replacement actuators are open-loop devices....

Precise fiber alignment is necessary for accurate and reliable data transmission in an optical network. Most optical networks have many optical couplings and even minor (< 1%) losses at these...

In optical tables, "noise" refers to three types of vibration: seismic, acoustic, and tabletop forces. Seismic vibrations come from the ground underneath the table and can be caused by foot and...

Lasers require precise alignment in their design to simultaneously deliver optimal power and provide ultrastability of the beam in position and quality. To meet this requirement, the laser designer...

The ability to control and manipulate quantum systems on the atomic and subatomic levels has given rise to quantum technologies that are transforming the world we live in. In particular, the growing...

Choosing the right positioning technology for an application is a complex task. There are numerous choices of linear stages, rotation stages and actuators and each product has its own advantages and...
