Variable Polarizing Filter
Our VP Filter has a range of greater than 90% to less than 5% transmission from 400nm to 700nm. When utilized in our special Model A or Model B VFA Adapter, light and dark contrasting is extremely improved. For example, in all achromatic refractors all secondary color fringe can be eliminated - WOW!
