At LTS Research Laboratories, Inc., optical coating materials are the foundation of our business. With over 20 years of experience, we specialize in the development and supply of high purity materials used in thin film optical coatings, including evaporation materials, sputtering targets, and custom e-beam compounds.

Our materials are engineered to support precise control over transmission, reflection, and polarization in advanced optical systems. From anti-reflective coatings and beam splitters to dichroic mirrors, polarizers, and UV/IR filters, we supply the materials behind the most demanding optical applications.

We offer a wide selection of:

Oxides (such as TiO₂, Al₂O₃, HfO₂)
Fluorides (such as MgF₂, LaF₃)
Metals (such as Cr, Al, Ni)
Custom compounds for application-specific deposition needs

Our products are available in multiple forms including sputtering targets, evaporation granules, pre-melted slugs/inserts, and engineered e-beam-ready mixtures, supporting deposition work from deep-UV to far-IR.

Every material is specified for:

Compatibility with substrates and co-deposited layers
High optical purity (typically 99.99% or higher on a metals basis)
Strong adhesion and minimal optical absorption
Suitability for vacuum deposition, ion-assisted coating, and plasma-enhanced processes

At LTS, we handle the materials science so you can concentrate on the coating process. Our materials support critical applications in laser optics, semiconductor fabrication, aerospace, defense optics, and precision instrumentation.
