19mm Polarizing Filter Set - NEW!
Brand new (but no box) set of two 19mm diameter, or just over 3/4", polarizing lens set. This offering is for the polarizing glass only. They do not come in metal or plastic cells. These are great for experimenting, and can be used on telescopes to reduce bright objects such as the moon and Venus. Just rotate these two in front of each other for light reduction depending on the rotation.
