Welcome to our NaCl windows catalog. Custom sizes and specifications of NaCl windows are available. Contact us for quotation.
We have long experience of supplying the windows of standard (catalogue) sizes for the commonly used instruments from Perkin Elmer, Nicolette, Bruker Optics, Pike, etc.
- Excellent Transmission from 250nm – 16µm
- Low Cost
- Ideal for FTIR Spectroscopy
- Packing: All NaCl optics carefully packaged into plastic boxes with silicagel and sealed with special moisture protective film.
