Topsil high transmission (HiTran™) silicon targets high quality IR applications and instrumentation. Due to its high purity, it has unique transmission performance across most of the infrared band, including the far infrared region. Transmission starts at 1.2 μm. Up to 7.0 μm there are no bulk properties limiting the transmission.
Typical infrared applications that will benefit from using Topsil HiTran™ silicon are thermal imaging systems, including multicolour infrared systems, silicon prisms, gratings, grisms, lenses and blanks, silicon fresnel lenses, passive infrared detector filters, transmission windows for debris protection, micromachined infrared devices, and silicon micro bolometers.
Topsil high transmission silicon is based on float zone technology and available in diameters up to 200mm.
