Fiber Optic Basics

 Tutorial
Optical fibers are circular dielectric wave-guides that can transport optical energy and information. They have a central core surrounded by a concentric cladding with slightly lower refractive index.

Light Collection and Systems Throughput

 Tutorial
This discussion is restricted to the general use of Incoherent Light Sources, such as arc lamp or quartz tungsten halogen sources. Diffraction and coherent effects are excluded. The emphasis throughout this section will be on the collection of light.

Laser Diode Technology

 Tutorial
Low-power laser diodes come in a variety of packages. Most have a monitor photodiode integrated with the laser diode. Generally, laser diodes emit light from both ends of their cavity. By monitoring the rear facet output beam of the laser diode, one

Grating Physics

 Tutorial
A typical diffraction grating consists of a substrate with a large number of parallel grooves ruled or replicated in its surface and overcoated with a reflecting material such as aluminum. The quality and spacing of the grooves are crucial to the per

Optical Power Measurement

 Tutorial
When a photon hits the photodiode material, it may generate an electron-hole pair depending on the quantum efficiency of the device. Quantum efficiency is dependent on many factors, but in general if the energy of the photon, E = hv, is greater than

Linear Translation Stage Terminology

 Tutorial
This glossary covers important terms related to linear translation stages.

Vibration Control Definitions of Characteristics

 Tutorial
This glossary covers the important terms related to vibration control.

Getting Light into a Monochromator

 Tutorial
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 Oriel Monochromators, the same general principles apply to collecting

Polarization in Fiber Optics

 Tutorial
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 components differ in phase or amplitude. Polarization in optical fibe

Introduction to Solar Radiation

 Tutorial
Radiation from the sun sustains life on earth and determines climate. The energy flow within the sun results in a surface temperature of around 5800 K, so the spectrum of the radiation from the sun is similar to that of a 5800 K blackbody with fine s
