HT Silicon

Product Information

 [HT Silicon] is under development silicon material, which improved less transmittance of 9um needs for human detection at far-infrared regions. Since this silicon material is low cost comparing with other materials for far-infrared transmitted materials such as Germanium, [HT silicon] is suitable material for low cost and mass production performance in lens of night vision camera of car or infrared camera.

Characterization

透過率グラフ

 Significantly, around 9um range of transmittance is improved a lot comparing with normal single crystalized silicon for semiconductor (right hand side graph).
 The manufacturing cost is the same as the one for semiconductors. So, applying this item for an optical purpose will make low cost and good performance in middle transmittance.
