Blakut: sunt tare curios cu ce camera, in care infrarosii si ce fel de geam l-ai vazut tu opac. Vezi mai jos ce importanta are "numai near infrared".

Si daca tot vorbim despre observatii solare si near-infrared.
Asa arata spectrul solar: the other half mostly in the near-infrared part. Some also lies in the ultraviolet part of the spectrum." near-infrared radiation :!:  causes heating that literally cooks the exposed tissue. This thermal injury or photocoagulation destroys the rods and cones, creating a small blind area. The danger to vision is significant because photic retinal injuries occur without any feeling of pain (there are no pain receptors in the retina), and the visual effects do not occur for at least several hours after the damage is done" :shock:    http://eclipse.gsfc.nasa.gov/SEhelp/safety2.html
