Variable Reflective Neutral Density Filter
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.
