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.

Details

◦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.

Name	Variable Reflective Neutral Density Filter BK7 100mm Diameter Wavelength 400-2000nm
Weight	0.0570kgs
Standard Coatings Available	No
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.
