 | High Energy Dielectric Attenuators
Substrate Material: Coating Technology:
BK7 glass Electron beam multilayer dielectric
Wavefront Distortion: Adhesion and Durability:
Transmitted - λ/4 at 633nm over Per MIL-C-675A
central 6mm diameter Insoluble in lab solvents.
Reflected - unspecified Angle of Incidence:
Thickness: 0˚ ± 10˚
200㎛ ± 50㎛ Housing:
Black anodized aluminum
* All dielectric, non-absorbing attenuators, T + R = 1
* Designed for transmissive applications
* Available Ti:Sapphire wavelengths
* High energy attenuator kits available, call CVI
High energy attenuators are designed for transmissive applications where non-absorbing coating and
substrate materials are required. Transmitted wavefront distortion is less than λ/4 over central 6mm dia-
meter.
Warning: reflected energy from uncoated surfaces may cause injury.
