Latest Patents

Murarka's latest patents include innovative technologies such as rugate optical filter systems. One patent describes a heterodyning interferometric monitoring apparatus designed for simultaneously measuring the optical and physical thicknesses of a sample during a deposition process. This system utilizes a linearly polarized monochromatic light beam that is transformed into a dichromatic light beam, which is then applied to a modified Twyman-Greene interferometer. This setup allows for precise measurements of both the physical and optical thicknesses of samples using heterodyne signal detectors.

Another patent details a method for fabricating graded refractive index rugate optical filters. This method involves using at least two different compatible thin film deposition source components, such as silicon nitride and silicon oxide, to create a thin film material with a variable refractive index. The process includes monitoring the physical and optical thicknesses of the coating to adjust the laser flash evaporation rates of the source components.
