Sodium chloride (NaCl)

Sodium chloride, Potassium chloride and Potassium bromide single crystals have uniform texture, bright and transparent. They are highly transparent to infrared rays. The thickness is less than 10mm, and the transmittance is more than 90% in the range of 4000-500cm-1. There is no impurity absorption.
It is a broadband good conductor from ultraviolet to mid infrared radiation; Widely used for infrared spectral analysis and the production of ultraviolet and infrared optical components. These single crystals are materials for making optical elements. They can be used as prisms, lenses, filters and transparent materials for various pool windows and laser windows in infrared devices and Optical instrument. At the same time, such crystals are also important thin film substrate materials, especially for the application of "membrane substrate" separation. This type of water-soluble substrate can easily dissolve the substrate with water, leaving only the thin film.

Dihedral Technology(DHD) Co., Ltd. manufacture and processing/provide multiple specifications and high quality NaCl crystal,targets,materials.

Applications

It is used to make prisms, lenses, filters, optical elements of various pools and laser windows in infrared equipment and optical instrument, as well as substrate and transport materials of films.

Features

The high transparency of sodium chloride (NaCl) crystal substrate, especially in the infrared region, makes it an ideal choice for infrared optical applications.
The low refractive index of sodium chloride crystal substrate has great potential for application in high-resolution optical imaging and spectral analysis.
The ion bonding properties of the substrate result in poor stability under extreme conditions, such as high humidity and high temperature environments.
The sodium chloride crystal substrate is easy to machine and polish, therefore it has advantages in the manufacturing process.
Due to its solubility, sodium chloride crystal substrates can be used as temporary substrates for biology or other fields that require temporary support, which can then be removed by simple water washing.
