|Is there any material that is totally transparent to entire spectrum of IR?.
Which IR (Near IR or Far IR ) is more thermal energy containing type?.
Which martial (Quartz or Saffire ) is having better transparency to entire IR spectrum? Is there any other optically conductive material which is having better conductance to entire IR spectrum?
Can the thermal energy pass through the IR transparent lens? While traveling through the IR transparent lens will be there any damage to the lens?
