Description
THE IR PASS FILTER IS DESIGNED TO COMPLETELY CUT THE FREQUENCIES OF THE VISIBLE AND TO LET THROUGH ONLY THOSE OF THE INFRARED, TO WHICH OUR EYES ARE NOT SENSITIVE: FOR THIS REASON IT IS A FILTER FOR PHOTOGRAPHIC APPLICATIONS ONLY.
IR PASS FILTERS ARE USUALLY USED FOR HIGH MAGNIFICATION Astrophotography. IN FACT, IN THE INFRARED SPECTRUM REGION, THE ATMOSPHERIC TURBULENCE IS LESS THAN THE VISIBLE REGION AND THIS ALLOWS TO RECORD GREATER DETAILS (FOR EXAMPLE, THE BEST PHOTOGRAPHS OF MARS AND THE MOON ARE ALSO TAKEN IN INFRARED). ATTENTION: TO PHOTOGRAPH IN INFRARED YOU MUST USE SPECIAL CAMERAS. IN FACT, NOT ALL ARE SENSITIVE TO SUCH WAVELENGTHS: MONOCHROME THOSE ARE GENERALLY GOOD WHILE COLOR THOSE ARE NOT GOOD TOGETHER WITH AN IR PASS FILTER.
