Bundle: AstroSolar Safety Film and Solar Viewers

Our Baader AstroSolar Safety Film does not have a fixed expiration date. When stored and used properly, it can be used for many years without any degradation of its optical or protective properties.

The most important point is to inspect the film carefully before every use. As long as it is free from scratches, pinholes, tears or other mechanical damage, it remains perfectly safe to use.

We still have many customers who regularly use AstroSolar filters that were built more than 20 years ago, including filters made for the total solar eclipse in 1999.

This film size will certainly not be available for some time. The reason is that we have to produce this size together with all other types and sizes of film because the production quantities of the special optical film and the effort involved are very large. Unfortunately, it is difficult to predict how long such large-scale production will take, but we are working on it. The best thing to do is to register using the "Notify me..." function, you will not be able to get information about when we will be able to deliver again any faster. We regret that we cannot give better information with a more precise time frame at the moment.

AstroSolar® Safety Film 5.0 is not authorized to be used for naked eye solar observation or production of solar viewers. For direct solar viewing without telescope, binocular or camera optics, inquire for our EN ISO 12312-2:2015-11 certified eclipse shades equipped with AstroSolar® Silver/Gold Film.

No, the film has the same coating on both sides and it doesn't matter which side you will face to the sun.

Los filtros astrosolares siguen siendo utilizables después de muchos años, si el filtro no tiene agujeros u otros lugares donde falte el recubrimiento. Por favor, sostenga el filtro frente a una lámpara brillante, si usted ve un cielo estrellado en los pequeños agujeros o lugares más brillantes, entonces la película debe ser reemplazada.
