Pinholes in thin-films
Pinholes are a problem for every coating manufacturer, but not for every customer! Depending on where in the optical path your filter is positioned, your system may be more or less sensitive to pinholes. Read this blog to learn more about what causes pinholes and when you need to worry!Pinholes are a problem for every coating manufacturer, but not for every customer!

Temperature effects on filter performance
In this post, we will describe how filter performance can reversibly shift with temperature. This can have big implications in outdoor or space applications where the filters are exposed to a large range of temperatures.In this post, we will describe how filter performance can reversibly shift with temperature.

Hard-Oxide PARMS Versus Protected Coatings
Omega Optical employs the widest range of coating technologies in the optical thin film filter industry. In addition to our high capacity, state-of-the-art Plasma Assisted Reactive Magnetron Sputtering (PARMS) systems, we’ve retained the ability to produce filters made with traditional inorganic compounds, typically zinc sulfide and cryolite. Each technology has its own strengths. In this post, you will discover more about these methods.Omega Optical employs the widest range of coating technologies in the optical thin film filter industry.

Farming goes high-tech!
In Vermont, we are very connected to where our food comes from. In our small towns, we interact directly with farmers every day. In this blog, learn how Omega is helping farmers go "high tech" to maximize output and minimize their costs.In Vermont, we are very connected to where our food comes from.

Measuring complex refractive index
We have learned in previous blog posts about the importance of knowing the refractive indices and thicknesses of the layers we are making. The interference, that makes our filters work, depends on it!

Making Waves Part Four
In this final installment of "Making Waves" we will introduce the Shack-Hartmann sensor. Omega uses this to measure wavefront distortion in coated optics, but it is also integral to the field of adaptive optics.
