Are these high quality optical glass filters? Heck NO! You would pay about $40.00 each for a solid optical glass filter, if you can find them. Even 3mm Lucite filters usually cost over twice my Buy Now price.

This is an affordable filter for the serious amateur, university student, high school lab, or even creative professional -

in thin, but sturdy, plastic.

 You simply cannot purchase ready-made optical glass cut into rings in our wide assortment of colors. Therefore, we highly recommend these which are hand cut from various plastic laminates, filter materials, and adhesive films.

Remember, be sure of your filter size, as these are 32mm in diameter.

Our techniques are professional, and we use precision equipment.

 Finally, we will unconditionally guarantee this filter 90 days, as we want it to work for you.

 We have other filters listed on eBay – combine two or more purchases and receive a free filter for each additional purchase!

Educators! We can offer discounts for purchases of 10 or more of this filter. Simply "Contact Seller" and tell us your needs.
