Coherence Width and Area Calculator

Coherence Width and Area Calculator is a handy tool that helps you understand one tricky part of optics: coherence. Coherence is how well a wave, like light, can stay consistent over time and space. There are two main types of coherence: transverse (spatial) coherence and longitudinal (temporal) coherence. Each one gives us different information about the wave.

Understanding Temporal and Spatial Coherence

The temporal coherence relates to the frequency spectrum, which tells us how long a wave lasts and its timing. On the other hand, spatial coherence depends on the size of the light source and how far it is from where you're observing it. That's where our Coherence Width and Area Calculator comes in!

No Installation Needed!

This app is super easy to use since it doesn't need any installation. You'll have it up and running in no time! The interface has just a few fields for you to fill out so you can find out both the coherence width and area.

Calculating Coherence Parameters

The width measures how far along the wavefront you go, while the area shows the surface where a specific degree of coherence stays steady. To get these calculations right, just enter some simple info:

• The diameter of your light source (in micrometers)


• The distance between your observer spot and the source (also in micrometers)


• The area of your source (in square micrometers)


• Your peak wavelength (in micrometers)

Once you fill all that out, boom! The app calculates everything for you quickly. You'll see the width in meters, while the area will show up in square meters.
