Contact us for advice solutions and equipment provider

Type of optics:

circular-step neutral-density
Other characteristics:

BK7

The Circular Variable Neutral Density Filter functions at an operating wavelength range of 380nm up to 2000nm in BK7. In UVFS, the wavelength dimension ranges from 250nm up to 25000nm. The device has a wide, finite aperture which can be tapered through rotating the two filters.

Models are available from 25mm up to 100mm. These filters also has an internal diameter of 8.0 mm and +0.0/-0.1 mm diameter tolerance. The protective chamfers have < 0.25 mm x 45°.
