1. What are Sodium Chloride Crystal Substrates?

Sodium Chloride Crystal Substrates are high-purity crystalline NaCl plates or windows with polished surfaces used as optical substrates, infrared windows, spectroscopy substrates, and thin-film deposition substrates.

2. What are NaCl Crystal Substrates used for?

They are commonly used for FTIR spectroscopy, infrared spectroscopy, optical research, thin-film deposition, surface science, vacuum coating, molecular spectroscopy, and materials research.

3. Why is NaCl used for infrared spectroscopy?

NaCl has excellent transmission in much of the infrared region, making sodium chloride optical windows and NaCl crystal plates useful for IR spectroscopy and FTIR applications.

4. Can NaCl Crystal Substrates be used for thin-film deposition?

Yes. NaCl single crystal substrates can be used as temporary or sacrificial substrates for certain thin-film deposition and materials research processes.

5. Can the substrate dimensions be customized?

Yes. REG Metals can source custom NaCl crystal substrate length, width, diameter, thickness, shape, flatness, and surface finish.

6. Are polished NaCl substrates available?

Yes. Single-sided and double-polished sodium chloride crystal substrates can be supplied for optical and spectroscopy applications.
