ISP Optics thin film coating lab offers a broad variety of deposition technologies allowing us to create custom coating solutions for the most demanding applications. ISP Optics utilizes multiple coating processes and technologies including thermal resistance and electron beam Physical Vapor Deposition (PVD), Ion Assisted Deposition (IAD), Chemical Vapor Deposition (CVD), and Plasma Enhanced Chemical Vapor Deposition (PECVD) to cover a wide range of design solutions over many different types of substrates.

ISP Optics are experts in optical thin film designs, with extensive experience designing virtually every type of thin film (antireflection, high reflection, partial reflection, bandpass, etc.). We focus on leading the industry in applications in SWIR, MWIR, LWIR, and multiband hyperspectral regions as well as moisture protective coatings on hygroscopic crystals including KBr and KRS. ISP Optics is known in the industry for world class solutions for laser designator and rangefinder applications, Forward Looking Infrared (FLIR), and Thermal Imaging.

All of the coating chambers at ISP Optics are equipped with the industries most advanced vacuum and monitoring technology with state-of-the-art software and hardware to fully control the entire deposition process. Our expertise in thin film coatings gives us the industry advantage in producing extremely stable dielectric coatings on a wide range of substrate materials including chalcogenides, germanium, silicon, zinc sulfide and zinc selenide. Our proprietary design solutions lead the industry in adhesion, hardness and durability requirements and can be deposited on various shapes and sizes including plano, radius, asphere and freeform.
