Tailor-made and with highest precision
Optical Windows
High demands – simple product solutions. Optical windows from MICROS Optics are characterized by high precision, low surface roughness, and minimal surface imperfections. We guarantee and document all test characteristics in a strictly enforced quality control process. For this purpose, we have precise measuring and testing equipment at our disposal.
In addition to a wide range of materials, our modern machinery enables us to produce high-precision optical windows with very complex geometries and structures – no matter how demanding your requirements are.
Do you have any questions about our optical windows? We are happy to help.
