Optical Housings
Jun 15, 2017

Baienwei provides controlled expansion(Si/Al) alloys,on account of lightweight,high modulus,the almost constant thermal expansivity,good machinability and custom designed prototype for applications in optical housings(70Si/Al alloy),which suitable for hermetic optical and opto-electronic housings.The alloys can replace a similar item that was fabricated by stainless steel,which suffers from numbers of drawbacks in operating.By comparision,the Al-70%Si alloy offers a lower CTE, a welcome reduction in weight, improved stiffness and rigidity, and dimensionally stable.


Applications include:

  • Polymer optics;

  • Custom optics,for example,the laser components,imaging components,machine vision components,bioinstruments&optomechanics.
