FTIR windows

product description

FTIR transmission windows - round,square,drilled, and customized Transmission spectroscopy is one of the basic techniques for IR analysis. The sample and wavelength to be analysed determine the choice of window material, path length and window arrangement.

Applications :


Product Advantage :

  • ICC supply various kinds of IR transparent materials most often used by IR spectroscopists like KBR, znse, zns, silicon, baf2, caf2, lif, fused quartz,etc, and these optics can be round, square, drilled and customized shape based on the ICC CNC machines ability, and all the materials have MSDS, rohs, and Reach files.
  • ICC supply the competitive price and reliable quality standard size windows to reach your fast project lifetime based on the popular material as following.
