Types of optical material elements

Optical elements are the basic components of optical systems, also known as optical components, which can often play the role of imaging, such as lenses, prisms, mirrors, etc.

Any instrument, device, or thing used to form an optical path, compose optics, or related to optics is an optical element. For example, a concave lens has a divergence effect on light. The incident light passes through the focus and refracts through the concave lens, and the refracted light is parallel to the main axis. A convex lens has a convergence effect on light. The incident light passes through the focus, and the refracted light is parallel to the main axis after being refracted by the convex lens.

Optical material elements sapphire

Sapphire is the hardest natural mineral on the earth besides diamonds, and its basic chemical composition is aluminum oxide. It transmits light in the range of deep ultraviolet to middle infrared. Sapphire has less thermal radiation than other materials at high temperatures, and its thermal emissivity is very low. Sapphire is very hard, which will make optical processing difficult.

Sapphire optical elements can be used in various applications requiring high durability or a wide spectral range, including semiconductor, FTIR spectrum, or FLIR imaging. Sapphire is the second crystal with high hardness. Its various properties make it suitable for harsh environments, including ultra-high surface hardness, high thermal conductivity, and high resistance to chemical acids and alkalis. Compared with a variety of standard optical materials, sapphire optical elements provide a thinner design with a transmission range of 0.15 – 5.5 μ m. In order to achieve the best performance from ultraviolet to middle infrared.

Optical material elements barium fluoride lens

Barium fluoride is a semiconductor material, often used as a laser crystal or as a high-purity electroplating agent. It has a high refractive index and low loss, so it can be used to manufacture efficient lasers. Barium fluoride crystals can also be used to manufacture optical components, such as prisms, beam splitters, and fiber amplifiers.

Barium fluoride crystals are usually prepared by placing or precipitation. In the placement method, barium fluoride powder is placed on the substrate at a high temperature and crystallizes with the increase in temperature. In the precipitation method, barium fluoride solution is usually used and dropped into the matrix solution to make the precipitated barium fluoride crystal grow on the matrix. Barium fluoride crystal has excellent optical properties, but its thermal stability is poor. Therefore, high-temperature heating should be avoided during use. In addition, barium fluoride crystal is also sensitive to oxygen, so attention should be paid to protecting against oxygen intrusion during use.
