Optical Windows, Light Transmitting Optics

Windows made of optical & technical quality glass

Optical windows are translucent optics that are used in technically optical applications. The materials used for the production of an optical window should be of high quality, in order to keep distortion low and to ensure a high imaging quality. If required, for example for imaging or laser applications, all optical windows can be tailored to customer specifications in terms of flatness, surface quality, shape and size. Also custom coatings can be applied to the optics, provided the required quantity is large enough for a coating run. We fabricate optical windows from any high quality glass material that is available. The list below shows a selection of the most common glasses that we use for the fabrication of optical windows. Please follow the links to the respective data-sheets for detailed technical information about the materials:
