Flats and Windows

Flat optics can be fabricated in a variety of geometries, including round, square, rectangular, and free form. Flat optics have a wide variety of applications, including windows, mirrors, filters, transmission optics, reference optics, and wedges. Windows are most often used to separate two environments while allowing light to pass. Reflections from their surfaces can also be used to sample beams.

As a world-leading manufacturer of high precision flat optics, Clear Align employs expert optical manufacturing technologies, including CNC machining, lightweight rotational double-sided conventional polishing, and thin film coating. Clear Align manufactures all of our flats and windows to laser quality, and available high power antireflection coatings on one or two surfaces.

Clear Align offers quick delivery on all of our custom flats and windows in your choice of wedge, diameter, AR/HC/DLC coating, and angle of incidence. Custom AR coatings can be also deposited on all of our substrate materials, as can any of our many dielectric and metal coatings. Whatever your needs may be, Clear Align has the expertise and high volume capacity available to create and deliver the best performing window or flat optical solution for your application.
