Choosing a Light Source

From UV to the IR, Pulsed or Continuous, Low to High power, Oriel Light Sources Have You Covered

Newport's Oriel® Instruments light source offerings are varied and significant. With so many options, it can be difficult to choose the best system for your application. For light source technical information, see the links to the right. For a summary of the major advantages of each type of light source see below. Also, don't hesitate to contact us directly at (800) 714-5393 or to consult with our Light Sources specialists to ensure that you choose the right light source for your application.

What Type of Light Source Do I Need?

Ask yourself the following questions to help determine the type of light source required:

1) Do I need a continuous or a pulsed light source?

We have a large selection of pulsed light sources as well as UV to far-IR continuous sources. See the information below on what we offer.

2) What wavelength(s) or wavelength region do I need?

Using the information below you can match a light source to your wavelength requirements.

3) What output power do i need?

You can use the spectral irradiance curves for the lamps to help you calculate the output power from an Oriel light source. You may need to compare the results of of several light sources to get the desired power at the required wavelength(s), as a almps input power is not directly correlated to output power.
