Low Observable / Stealth Coatings

Spectrally tailored pigments are incorporated into paint or ink formulations with application and cure mechanics specifically tailored to customer end-use

We use optical coating expertise to create unique, spectrally tailored paints. Releasable PVD thin film coatings are processed into spectrally tailored flake pigment. Wavelength-dependent reflectance and absorption can be customized to customer requirements using design principles of optical interference coatings.

Innovative Roll-to-Roll Process

Our unique roll-to-roll coating process was developed in-house for Electron Beam, Jori Source, and Ion-assisted deposition (IAD) of metallic and dielectric films (all processes scalable).

1.8m and 5m chambers accommodate a variety of applications, with deposition on film up to 1000m x 1.5m wide and a great deal of experience handling sub-10 μm films.

Developed by SOC

A unique capability of our lab

Substrate moves across 4 banks of e-beam guns

Allowing up to 4 discrete layers per pass.

PID programmed rate monitoring

Allows for precise uniform thickness deposition.

Film conversion Re-Winder

Cleanroom film handling (ISO Class 5), at atmosphere for pre and post processing.

Modeling

Surface Optics maintains a variety of analytical models to predict surface scattering and heat transfer. The test data for each surface design will provide inputs to these models to provide an iteration to the development process.

In-house developed Scattering Coatings Computer-Aided Design (ScatCad) program

Predicts spectral BRDF and HDR of coatings and surfaces. First principles radiative transfer model, includes binder absorption. Based on optical constants and micro-physical composition. Provides analysis of diffusely scattering surfaces.

Surface Optics developed ENSemble of InfraRed (ENSIR) analysis code

Used to predict the performance of the spectrally tailored coating. Optical coatings mapped to surface elements. User defined multispectral environment. Coupled finite element radiance and internal/external thermodynamic heat flows. Embedded MODTRAN atmospherics.
