Design Guide for Thin Film Coatings
Thin film coatings, such as antireflective (AR) coatings, are made from various materials, such as metals, oxides, and compounds, and are deposited in layers onto a substrate. Thin film coatings can be deposited in both single and multiple layers, and the configuration you choose determines how it will manipulate different wavelengths of light. Thin film […]
Applications of Optical Microscopes
Optical microscopy is a technique that allows the viewing of samples more closely using optical microscopes. It relies on light and one or more lenses to magnify samples. Optical microscopy is remarkably versatile, increasing the detail and contrast of a microscopic specimen. A range of applications rely on simple and complex microscopy techniques. Fluorescence Fluorescence […]
Ion Beam Sputtering
Ion Beam Sputtering Coating (IBS) uses an ion source to deposits or sputters a thin film onto your targeted material (either metal or dielectric) to create a dielectric or metallic film. Since an ion beam is mono-energetic and collimated, it creates very precise control over the thickness of the film. A typical configuration of IBS […]
A Brief Guide to Thin-Film Optical Filters
What Are Thin-Film Optical Filters? Thin-film optical filters are optical devices consisting of alternating thin layers of specialized optical coatings deposited onto a substrate (e.g., optical glass). The coating layers alter the refractive index of the substrate, changing the direction of the various wavelengths in incoming light as it passes through one layer to the […]
A Brief Guide to Beamsplitters
What Is a Beamsplitter? Beamsplitters—also referred to as beam splitters or power splitters—are optical devices designed to split incident light into two or more separate beams. They can also be used in reverse to combine two or more separate beams into a single one. Some of the key properties to keep in mind when choosing […]
