Introduction:
These circular, continuously variable neutral density filters provide adjustable attenuation via rotation. The optical density (OD) increases linearly from the start of the coating. The filters are coated through a full 270?? arc.
Features:
Optical Density Range: 0.04 - 2.0 or 0.04 - 3.0
Ø25mm,Ø27mm,Ø30mm,Ø40mm,Ø50mm,Ø75mm,and Ø100 mm in diameter
Back-Side Coating: usually uncoated, or upon request for AR coating over certain band.

Substrate Material:
UV Fused Silica; Disc type; Operation wavelength:200-2500nm
Central Hollow:
Dia 27.0,-0/+0.1mm thru in diameter for clear field view
Coating:
Single-surface Nickel-deposit coating (0 - 270 deg coated)
Coating coverage: 100%
Outer/Inner Diameter:
Dia 50.0,-0.1/0mm/Dia 27.0,-0/+0.1mm
Thickness
2.0,+/-0.1mm
Surface Quality
40/20 S/D per MIL Standard
Flatness
<Lambda/4 at 633nm over 1-inch area on-jig tested
Optical Density
