22 Jul 2024 At Avantier, we possess the expertise to produce custom optical domes solutions in a wide variety of substrates and sizes. Whether you require enhanced durability for high-pressure environments or precise optical quality, our team can design and manufacture the perfect optical dome tailored to your specific application.
Optical domes, also known as hemispheric optical windows, play a crucial role in transmitting light while providing a protective boundary between two systems or environments. These specialized optical components are commonly used to safeguard fragile optical systems in demanding applications. For instance, in aerospace engineering, they protect LIDAR optical sensors from the impact of fast-moving objects.
