pdfPolymer Optics for Industrial Use (PDF)

IR windows can be quickly divided into two camps -- those with industrial-grade optics made of polymer, and those that use a crystal optic that is better suited to laboratory use. This tech-note will touch on some of the benefits that industrial-grade polymers offer for use in electrical inspections:

-- What are the advantages for data accuracy?

-- What are the advantages for durability and impact resistance?

-- What are the advantages for longevity and environmental compatibility?
