Spectrum Telescope manufactures durable, high quality solar filters that are the safest on the market for viewing the sun. These white light solar filters prevent damage to your equipment or your eyes as you view granulating, sun spots, or a solar eclipse. They fit cameras, small reflectors, spotting scopes, telescopes and view finders as well as binoculars. We have been building and developing safe solar filters for over 20 years. We will soon be adding telescope accessories to our line of products and we are constantly developing new products that will be introduced soon. Each member of Spectrum Telescope’s team are customer oriented and work hard to establish a bond with each one.
Are the glass and film solar filters safe?Yes, all of our filters are safe, blocking up to 99.999% of the sun’s rays, perfect for unlimited visual use as well as photography. These filters are rated with a neutral density of 5. With proper care and handling, our filters will last for many years. Spectrum Telescope ISO Certified 12312-2 while meeting or exceeding International Standards for safety.
There is some confusing information and articles out there about solar viewing. To clarify, ISO and CE Certification for Solar Filters does not exist. Any company or article providing information that there is a Certification process for Solar Filters is providing false information. Companies that are claiming they have ISO Certification on their Solar Filters are not being honest. There is a standard established by ISO, but no body to certify filters yet. Spectrum Telescope Solar Filters have been sent to an Independent Laboratory which have documented that these two products are safe for viewing and photographing the sun and meet the requirements for ISO 12312-2. A NASA and Observatories all over the world have purchased Spectrum Telescope Filters for over two decades.
