Review: works great !! easy to cut. easy to use. absolutely love it !! - works great !! easy to cut. easy to use. absolutely love it !! i got mine back in April 2023 and ive almost used it all now. used my 3D Printer to make adapters to use this for my telescope and finder scopes. i got a 130mm telescope for xmas and just used the last large piece i had left. Review: Complete Totality - It's the real deal, made in the USA. This stuff was more valuable than gold in the days before the GAE and everybody wanted it. I tested it against various high-brightness sources such as high intensity 5W LED flashlights, and a 100mW 395nm UV laser. You could see the LED die structure in great detail with the minimal amount of light that would pass. This filter material would be perfect for inspecting LED die structures or as a means of taking low intensity measurements for quality control. The UV laser would not pass through the filter at near 100%. Only the occasional photon or two would pass when moving the laser at different angles, due to what I think is scattering. I tested some of the recalled solar viewing glasses from China and found that there was varying degrees of UV light passage in about 30% of my sample. Please, folks, don't do this kind of testing with your eyes and instead use a camera as a sensor. I made various camera filters out of the filter film by carefully tracing the glass element of a disassembled UV filter and then reassembling the filter with the film behind the glass. Even my besting cutting skills weren't enough to prevent imperfection around the edges, and that is why I put it on the backside. The compression of the glass ensured the filter film was against the back inside edge of the black anodized aluminum UV filter assembly and prevented any light bleed. Ideally, laser cutting these would be better. For personal viewing with my 20-100 x 70mm monster binoculars, I crafted two identical cardboard tube rings around the outside edge of the objective lenses with a few wraps of coiled 2" wide card stock cut from cereal boxes and then a few wraps of tape to hold them together. I then put strong double-sided tape around the outside of the tube rings. The filter film was cut into 3/4" oversized circles using appropriately sized round plastic food containers as a template. I then set the binoculars upright with these card stock ring sleeves and centered them over the pre-cut circular filter films. With everything aligned and pressed against the filter film and a cutting surface, I cut outward radial slits into the film "over-sized area" around the peripheral of the card stock rings at 1/2" intervals. This allows one to fold these "flaps" of film onto the sides of the tubes and double sided tape, to tape everything together. A few more layers of silvered Mylar tape were wrapped around these flaps to seal everything up. Complete totality was observed from Franklin, MO, which is on the center line of totality for the GAE and provided us 2m 39s of viewing. The local weather conditions were slightly hazy, and so we were able to make out detail on the surface of the moon due to the slight dimming of the Corona. It was the most amazing astronomical convergence I've ever seen. If you missed it, you really missed it. ## Features - Silver-Black polymer is the most common filtering material for observing sunspots and granulation, through telescopes and binoculars. - These sheets are a quality product of Thousand Oaks Optical, Arizona, a manufacturer of safe solar filters for over 30 years.

I ask because Amazon recently notified me that an item we gave as a gift was counterfeit. Eyes too valuable!** A: Yes, preparing for August eclipse, I've made several filter holders for both telescopes and binoculars with this material from Thousand Oaks Optical. (Sandwich a circle of the material between two slightly-larger rings of 1-inch and 1/2-inch thick Styrofoam using white glue. Inside diameter of 1-inch ring should make snug fit over telescope or binocular. Be sure silver side of film faces out, toward the sun.) **Q: will this cover a 95mm lens?** A: You could make at least 4 out of each sheet, and depending on how you mount it, possibly up to 9 95 mm circles. **Q: I have an astroview 120 eq telescope will the 12"x 12" solar filter work for me to make a filter? Is this all i need to view the sun?** A: I used it on a 50 mm finderscope and a 30 mm finderscope - they worked fine. I also built one for a 5 inch scope, but haven't tested it yet. Make sure that you build the filter to fit over the aperture (the big part of the scope), not the eyepiece. Also, be very careful about possible light leakage. And don't try to locate the sun in your scope via the finderscope, unless you have a solar filter for that too. ## Customer Reviews ### ⭐⭐⭐⭐⭐ works great !! easy to cut. easy to use. absolutely love it !! *by M***! on February 11, 2026* works great !! easy to cut. easy to use. absolutely love it !! i got mine back in April 2023 and ive almost used it all now. used my 3D Printer to make adapters to use this for my telescope and finder scopes. i got a 130mm telescope for xmas and just used the last large piece i had left. ### ⭐⭐⭐⭐⭐ Complete Totality *by I***M on August 31, 2017* It's the real deal, made in the USA.

The filter does a good job of filtering sun's energy to a point it can be comfortably viewed by eyes. The sun appears to be an orange orb which is normal. If you're going to take photographs of the sun, use this filter and put the camera on a tripod. to get the sun pics. Exposing for the sun through the filter, everything but the sun will be very dark, almost blacked out. If you want some of the surrounding landscape for context, keep your camera on the tripod, then wait for the sun to move out of frame, take a few pictures exposed properly for the landscape and then stack all of your photos as an HDR image in your favorite photo editing software. ## Frequently Bought Together - BP-1212 - Silver-Black Polymer Solar Filter Film Sheet (12" x 12") - 1 ea - 4"x4" Solar Filter Sheet for Telescopes, Binoculars and Cameras - Thousand Oaks Optical 6"x6" Solar Filter Sheet for Telescopes, Binoculars and Cameras --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/2664531-bp-1212-silver-black-polymer-solar-filter-film-sheet-12](https://www.desertcart.tn/products/2664531-bp-1212-silver-black-polymer-solar-filter-film-sheet-12) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-04-22*
