Optical Windows Selection Guide - Newport

An Optical Window is an optically flat, transparent optical material that allows light into an instrument. Newport offers a wide variety of optical windows made from materials like N-BK7, Fused Silica, Sapphire, Germanium, Zinc Selenide, Calcium Fluoride, and Magnesium Fluoride. Parallel or wedged optical windows can be purchased with laser grade surface quality and surface flatness for common or very demanding interferometer measurements. Newport also offers anti reflection coated optical windows to improve the transmission from UV to IR wavelength regime.

Learn All About Custom Optical Windows - Sterling Precision Optics

Custom optical windows are a great way to improve the performance of your optics system. By customizing the shape, size and material of your optical window, you can optimize it for your specific application.

Different Materials Have Different Properties

There are many different factors to consider when designing a custom optical window, such as transmission, reflection, scattering, birefringence, and polarization. The type of material used is also important, as different materials have different properties that can affect the performance of your optics system.

Maximize The Benefits of Using Custom Optical Windows

If you are looking to improve the performance of an optics system, custom optical windows are a great option. With careful design, you can maximize the benefits of using optical windows in your system.

Custom Optical Windows Tips:

-Consider the environment in which the window will be used. Will it be exposed to harsh chemicals or extreme temperatures?

-Think about the function of the window. Does it need to be optically clear, or can it be made from a material that is not completely transparent?

-Choose a material that is compatible with the other components in your system. For example, if you are using an infrared camera, you will need an infrared-transmissive material.

-Make sure the thickness of the window is appropriate for your needs. If you are looking for a very thin window, consider using a film instead of a traditional piece of glass or plastic.

Be Sure to Ask for Samples Before Making a Final Decision

Once you have considered all these factors, you can start shopping around for custom optical windows that meet your specific needs. You may want to contact a few different suppliers to compare prices and turnaround times. Be sure to ask for samples before making a final decision.
