AR Coated Tubes and Cylinders

Uniform coatings on highly curved optical components, such as tubes, cylinders, and domes, are inherently challenging to achieve in most thin film deposition processes. In typical line-of-sight deposition processes, such as evaporation and sputtering, curved parts become more thickly coated at their centers and thinner at their edges. Continuous rotation is typically needed to avoid uneven coatings on cylinders and tubes, but it’s difficult to implement in most thin film coating methods. Unique sputtering techniques and tooling are often needed to effectively produce uniform coatings on highly curved optics. IsoDyn is an adaptation of low-pressure chemical vapor deposition (LPCVD). It addresses the challenges of coating highly curved optics in line-of-sight deposition methods. IsoDyn technology simultaneously coats both the inside and outside of curved components, producing an even thickness on the entire part. The process is particularly useful for highly curved optics and complex shapes and is ideal for depositing ARs onto unusually shaped parts. DSI’s IsoDyn method offers several benefits, including:
Coating deposited on entire surface
· Dense, highly durable coatings
· High temperature survivability
· Temperature and humidity stability
