CVD Diamond Window For High-power Laser System

CVD diamond window overcomes many limitations of other optical materials with properties well matched to challenging applications involving high-power lasers, hazardous environments, extreme temperatures, or broadband transmission needs. When properly manufactured and applied, CVD diamond optical windows can provide unparalleled performance and durability under conditions that would quickly degrade most other conventional optical materials. For its unique benefits, CVD diamond offers an essential solution as a next-generation window technology for demanding optical systems.

 

We provide high-quality CVD diamond optics ideal for the most demanding applications requiring extreme durability, a high laser damage threshold, or broad spectral coverage. They provide immunity to damage from harsh chemicals, radiation exposure, or extreme pressures that would quickly degrade other optics. They remain transparent in highly corrosive gases and direct contact with acids or bases that dissolve most other materials. Our CVD diamond offers a universal solution for applications requiring transmission at both UV and IR wavelengths where no other material will surface. Furthermore, we boost performance through post-growth processing and characterization to maximize consistency, precision diamond machining and polishing techniques for ultra-smooth surfaces, etc.

 

We invite you to experience for yourself the immense advantages of CVD diamond. When other materials cannot realistically be considered due to their limitations, our CVD diamond windows offer an affordable alternative for guaranteed performance. For more information, please send us an inquiry.

How are optical windows mounted in an instrument?

Optical windows are typically mounted in instruments using one of several methods:

 

• Window mounts - The simplest method is to use a basic window mount that holds the window in place. Window mounts are frames that securely contain the window, often using an O-ring or gasket to seal it against a surface in the instrument. Common types include circular mounts for laser windows and rectangular mounts for optical viewports. The window is clamped or bolted in place using the mount.

 

• Threaded retainers - Windows can also be mounted using threaded retainers, where the CVD diamond window or window mount has threads that screw directly into a threaded port on the instrument surface. An O-ring or gasket seals the window when it is screwed in place. Threaded mounts allow easy removal and replacement of windows.

 

• Bonded or cemented windows - For some applications, windows are bonded or cemented directly to the instrument surface using epoxy, UV-cure adhesive, or other optical cement. This creates a permanent, airtight seal and window installation but also prevents the removal of windows if replacement is needed. Cemented windows must have high bond strength to withstand pressures and temperatures within the instrument.

 

• Soldered windows - Similar to cemented windows, some optical windows are soldered in place using a solder alloy with a low melting point. The solder forms a seal between the window edge and the instrument surface. Soldered windows also cannot be easily removed but may allow a seal to withstand higher temperatures than typical cement. To create a reliable seal, the solder alloy must be compatible with the window and surface materials.

 

• Flanged windows - Flanged windows have an integral flange or lip extending outward from the window edge. The flange allows the window to be flush-mounted to a surface opening, with the flange extending to lie flat against the surface around the opening edge. The window is clamped, bolted, or sealed against the surface. Flanged windows provide an unobstructed window aperture and space for O-rings or gaskets, allowing some removal if needed.

 

• Vacuum fittings - To install windows in a vacuum system, they can be attached to the window and used to mount it within a vacuum chamber. Fittings like CF and KF flanges provide a pressure-rated seal, allowing "clam-shell" window clamping between two segments. Vacuum fittings must be made of materials compatible with ultrahigh vacuum if used in UHV systems. They provide both sealing and gripping force to hold windows under vacuum securely.

 

The specific method to mount an optical window depends on factors like pressure differentials across the window, operating temperatures, window removability needs, available space, and window/instrument materials. Multiple methods, such as a window mount with a vacuum fitting, may also be combined. In all cases, the goal is to securely contain and seal the window to create a transparent barrier between the two environments. Proper window mounting is essential to ensure stable, long-term optical performance.
