When light passes through an optical material, how much of it actually makes it through?

Optical transmission describes the amount of light that passes through a material at a given wavelength. The amount transmitted depends on factors such as the material itself, its thickness, surface reflections, and any optical coatings.

For applications involving lasers, imaging, and sensing, choosing a material with the right transmission characteristics is essential to system performance.

At Meller Optics, material selection is an important part of fabricating optics for demanding applications.

Germanium is another important material for infrared optics.

Its broad infrared transmission and high refractive index make it useful in thermal imaging, infrared sensing, and other IR applications.

Material selection ultimately comes down to the requirements of the system, including wavelength, environment, transmission, and performance.

Optics Minute: What Does λ/10 Mean?

You may have seen optical specifications listed as λ/10 flatness. But what does that actually mean?

The λ represents the wavelength of light used for the measurement. A λ/10 surface has a maximum deviation from flatness of one-tenth of that wavelength.

In precision optics, surface flatness can directly affect wavefront quality and overall optical performance.

It's a small measurement, but an important one.
