Getting Light into a Monochromator

In this section we give a brief introduction to getting light into a monochromator, and how much you can expect to get out. While the emphasis is on coupling Oriel Light Sources to …

Tutorials

Polarization in Fiber Optics

A beam of light can be thought of as being composed of two orthogonal electrical vector field components that vary in amplitude and frequency. Polarized light occurs when these two …

Resolution of Monochromators and Spectrographs

Gratings are available in various groove densities (i.e. lines/mm). Higher groove densities give higher reciprocal dispersion and therefore higher resolution. The grating dispersion …

Tutorials

Fundamentals of Vibration

Vibration and vibration isolation are both intimately connected with the phenomenon of resonance and simple harmonic motion. A simple example of harmonic motion is a mass connected …

Tutorials

High Speed Detectors

There are many common parameters one considers when selecting a detector for a particular application. These include pulsewidth, bandwidth, responsivity, spectral sensitivity, noise …

Tutorials

Laws of Radiation

Everything radiates and absorbs electro-magnetic radiation. Many important radiation laws are based on the performance of a perfect steady state emitter called a blackbody or full radiator. …

How the Picomotor Actuator Works

The Picomotor's actuator relies on the basic difference between dynamic and static friction. A graphic example of this is the “tablecloth trick,” in which a quick pull of the cloth …

Tutorials

Environmental Vibration Criteria

These generic criterion curves have been developed on the basis of data from individual systems and measurements made in facilities both before and after vibration problems had been …

Tutorials

Understanding the Compliance Curve

No actual structure is a perfectly rigid body - all structures vibrate by flexing and twisting. The response of structures to random vibrations can be quite complicated because they …
