"In a neodymium spot lamp, especially one around 50W, infrared (IR) radiation is typically present, though it can vary by lamp design. Here’s a general breakdown of infrared wavelengths:
IRA (780–1400 nm): These are near-infrared rays, closest to the visible spectrum and make up a significant portion of the IR radiation emitted by incandescent or halogen lamps like a neodymium spot lamp. The IRA range is often the most abundant IR radiation, comprising 60-80% of the total IR output.
IRB (1400–3000 nm): Mid-infrared rays, contributing less than the IRA range. For a typical neodymium spot lamp, IRB might make up 10-30% of the total IR output.
IRC (3000–1,000,000 nm): Far-infrared rays are usually minimal in standard lamps and tend to contribute less than 5% of the IR radiation. This is due to the lamp's design and the relatively lower power to generate far-infrared wavelengths.
The exact percentage can vary based on the lamp’s specific construction and materials. Neodymium glass does filter some IR wavelengths, but these values provide a reasonable approximation for a 50W neodymium spot lamp."
So IRA accounts for 60-80%, IRB accounts for 10-30% and IRC is the least amount. I know at least that IRA and IRB are more crucial but is this distribution accurate? Can anyone fact check it or?
