Designed to let light into an optical instrument, optical windowsare flat plates constructed of an optically transparent substance. They may also be used to shield a light source from the outside environment. These windows are made to maximise transmission over a desired wavelength range while minimising reflection and absorption. When selecting optical windows, one must consider the mechanical parameters required by your application, the optical surface specifications, and the material transmission characteristics.
When choosing custom optics for your application, you should keep in mind the optical surface parameters and the substrate qualities. Transmission, refractive index, and hardness are all dependent on the material characteristics of the substrate being employed.
Sapphire Windows are considered among the best optical windows for industrial applications. As sapphire optics have superior strength and scratch resistance, customised optical components made using sapphire are excellent at protecting delicate lasers, sensors, cameras, and other devices. Here are some of its prominent optical properties.
In high pressure or vacuum situations, sapphire is often used as a viewport. Due to its high modulus of rupture, pressure windows made of sapphire can be much thinner than those made of optical glass. The majority of manufacturers apply an anti-reflective coating to the optical windows, which increases durability and efficiency. Most of the leading optical component manufacturers provide custom optics using a variety of materials such as silicon optics, sapphire optics, and more.
