EF-Series IR Sources

Pulsable IR Sources EF Series – NiCr Filament

 

IR12

 Nichrome (NiCr) filaments are made from ultra thin metallic strips. The metallic strips have a very high surface to volume ratio and thus a very short thermal time constant. They heat up and cool down or modulate very rapidly. The elements are typically attached in a series configuration to increase the overall resistance of the emitter (EF-series). This unique design avoids the problem of “current crowding” which causes uneven heating of the radiating elements often encountered with planar IR emitters. Window options denoted by X include: No Window (X=0), Sapphire (X=1), CaF2 (X=2), ZnSe (X=3)

 

 

Key Features Include:

NiCr filament with emissivity of 0.88

Uniform emitting area and temperature with no “current crowding” effect

NiCr filaments operate at peak temperature of 700°C (973°K)
