◦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.

| 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. |
