High Vacuum Viewports
At Thorlabs, we constantly reinforce our desire to serve at the pleasure of our customers. From this comes our desire to be connected to our industry in a way that far exceeds what would typically be expected of a vendor. Thorlabs lives this core principle by seeking to enhance, at every turn, the productivity of our customers. We have developed a culture that constantly seeks your input; many of you have experienced this first hand, as a large portion of our product offerings are customer inspired. Others may note that a website feature exists because you let us know that it would make you more productive. A direct outcome of this customer focus is our utmost respect for your time. This drives us to question everything we do. It informs our product design, shapes our approach to manufacturing, and provides clarity for our customer service department. We constantly ask ourselves how we can make the entire process of finding, understanding, purchasing, and using a product more efficient. By saving you time, we enhance your productivity, which allows us all to foster the continued forward movement of photonics. Thorlabs offers both flat and wedged windows fabricated from a variety of substrate materials. Many of our windows are offered with or without AR coatings. Conductive windows, high vacuum conflats and windows, and Brewster windows, which eliminate p-polarization reflectance, and UV fused silica windows designed to be oriented at 45° AOI are also available.
