It is difficult describe accurately. It is a collection of different filter and other materials made by the English company Lee Filters. They carefully dye web of polyester so filters with very specific transmission characteristics are produced. Listing all the filters will take too much time.
Each filter has accompanying data sheet. More include a spectral transmission curve. See the photos. The photos show the range. I estimate there are more than 125 filters. Each filter and data sheet are about .007inches and the pack is 1.25 -inches.
The filters are in very good to excellent condition. No scratches, tears, fingerprints etc.
To purchase send a personal message (PM) to me with your email. Serial communication through PM can be troublesome
Here is a list of ALL the Lee Filters that were made. All may not be included in the Sampler I am selling. They added and discontinued filters. The list does give an idea of the range they produced.
