Lattice Electro Optics operates in-house thin film design/coating facilities to provide optimum performance of lenses and laser mirrors. Lattice’s own design engineers who are the industry’s best educated and trained went through extensive on-the-job training in optical system designs and thin film coatings. They understand the vacuum coating equipments and their ultimate capacities in their heart. This ensures that you are guaranteed to get the highest quality products in the fastest turn around at competitive cost.
We, at Lattice, provide complete optical components from extremely deep UV (EUV) to far infrared (FIR) with the highest possible damage threshold optical coatings include all dielectric coatings as well as broadband metallic or metal-dielectric hybrid coatings. Many of the top notch scientists and engineers of the industries and several National Laboratories may testify how confident they are on Lattice’s products and service.
Brief summaries of routine coatings and typical their characteristics are given in this chapter.
