Alfa Aesar is pleased to offer a line of optical transmission windows for infrared spectroscopy. Disc or rectangular windows are available either polished or unpolished. A polishing kit is offered for those who wish to polish their own windows. Please inquire for sizes not listed. When ordering drilled crystals, please specify center or diagonal drilling.

We also offer the Crystal Polishing Kit, which contains everything needed by the spectroscopist for repolishing and buffing most infrared transmission crystals, including KRS-5. Two ground glass discs are provided --one for fine grinding and the other to which self-stick polishing pads may be affixed.

Alfa Aesar also offers Ruby and Sapphire Spheres for your analytical needs.
