This solar filter is made to thread into camera lenses. The filtering material in the aperture of the filter is made with .002″ thick Helios Solar Film. It’s strong, durable and has a one layer design with absorptive filtering material spread throughout the substrate. It has a rating of Neutral Density 5, which blocks 99.999% of all light, including harmful IR and UV rays. It is safe for photography if the viewfinder looks directly through the lens like an SLR or DSLR. When used properly, a natural yellow-orange image of the sun is viewed through the filter. Dependent on the size and strength of the lens, you will be able to see solar granulation (suns photo-sphere). Sunspots, planet transits, and a solar eclipse may be observed when present. If you are unsure of the right size filter for your camera, contact us by email (firstname.lastname@example.org) and we will be happy to help.
WARNING: DO NOT USE AS A DROP-IN FILTER. PERMANENT EYE DAMAGE CAN OCCUR, ALWAYS MAKE SURE THE FILTER IS SECURELY ATTACHED TO THE SKY END OF THE OPTICAL DEVICE (INCLUDING VIEWFINDERS) BEING USED. OUR FILTER SHOULD BE FIRST IN LINE ALWAYS! NEVER OBSERVE THE SUN WITHOUT A PROPERLY ATTACHED FILTER OR WITHOUT PROPER EYE PROTECTION.
