We are excited to finally be able to offer CVD grown and optically polished diamond windows for the MPY series detectors. These offer supreme broadband transmission from the UV (~225 nm wavelength) into the far infrared / Terahertz spectral region.
This makes this window an excellent choice for multispectral or spectroscopic applications (cf. our tutorial on how to build an FTIR).
Furthermore, diamond is hard, chemically resistant and does not degrade unlike other hygroscopic IR window materials like KBr and CsI.
For further information please don't hesitate to contact us.
Update March 2020:
We can provide the diamond window now for all available detectors (MPY and SPY series).
