Product Details
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.
application
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.
characteristic
• The Potassium bromide (KBr) crystal substrate has excellent transparency in the mid infrared and far infrared regions, and is widely used in Infrared spectroscopy.
• The Potassium bromide crystal substrate is easily soluble in water at room temperature, which limits its application in wet or high humidity environments, but also makes it relatively easy to clean or reuse this substrate.
• Potassium bromide has low hardness and is relatively easy to cut and polish, which is suitable for preparing thin film substrates.
• The Potassium bromide crystal substrate has certain ionic conductivity, which has potential applications for some electronic and photoelectric equipment.
• The refractive index and optical absorption characteristics of Potassium bromide make it suitable as a substrate for optical and electronic equipment.
