Bristol Instruments designs, manufactures, and markets precision instruments based on its expertise in optical interferometry. Bristol’s flagship products accurately characterize the wavelength and spectral properties of lasers used by scientists and engineers at universities, government laboratories, and industrial laboratories. They are also used for the development and production testing of laser transmitters used in optical fiber communications. In addition, Bristol Instruments provides interferometer-based products to reliably measure critical physical dimensions of materials such as specialty plastic films, medical membranes, and ophthalmic products.
