Variable Reflective Neutral Density Filter Sythetic Fused Silica 100mm Diameter Wavelength 200-2000nm

VND-100U

The VND is a reflective ND filter. The reflectivity and the transmittance vary by rotation. They are used mainly for light intensity adjustment in vision or illumination experiments.
◦Possible to adjust the intensity by rotation continuously or select light intensity position.
◦The transmittance light can be adjusted logarithmically, it makes dynamic light intensity adjustment possible.
◦Thin and space saving, it is easy to be placed in a narrow optical test set up.
◦The VND-U model is adaptable for use at Ultraviolet bandwidth made of fused silica.

Guide
  • For AOI (Angle of Incident) changing, the transmittance can be also changed. We recommend to use with the VBS, Variable Beam Splitter.
  • WEB Reference Catalog Code/W3022
Remark -
Attention
  • The round shape variable ND filter is very fragile. The bore is made of glass. Do not force on one surface of the bore when fixed in a holder, it could be broken. For a compatible ND filter holder (NDHN) for your optics replacement on to the holder, please contact our Sales Division for assistance.
  • The Chromium film coating is absorptive, please avoid to use with high power laser.
  • High power laser light can have thermal lens effects, please use (VBS) Variable Beam Splitter for high power and high energy laser applications.
  • WEB Reference Catalog Code/W3022
  • The reflected laser light beam is dangerous for eyes, the user must be aware and be prepared to use unreflective tools at the end of the laser beam.
  • The normal incident of the laser beam may produce optical feedback, to avoid this situation please use it with a small incident angle.
  • Incident light with large beam onto the Variable ND can produce a laser strength inside of the beam. Use incident light to the filter with a narrow beam.
