Brown fused alumina melt film precision casting sand is based on the production of the brown fused alumina and with special technology, it is produced by the careful organization of the researchers. The quality has reached the advanced level of similar foreign products through laboratory tests and production in practice of dozens of casting enterprises. And some performances of it can be adjusted or showcased according to the customers requirement. The precision casting sand with high refractoriness, low thermal expansion coefficient, good thermal stability, strong air permeability, high intensity, easy to shell, high casting finish.It can substitute Zirconia sand (powder) its price is only half of zirconia sand (powder), and the recovery ratio is high as well. It can be mainly applied to the melt films and silicasol technology of jewelry, handicrafts, stainless steel products, watches, glasses, aluminum die casting industries, and can be processed in line with the demands of the clients.

The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction. Zero order waveplate shows better performance than low/multiple order waveplates. It has broad bandwidth and a lower sensitivity to temperature and wavelength changes. It should be considered for more critical applications.
It is constructed of two low order waveplates with their axes crossed. Thus,the effect of the first plate is canceled by the second,except for the residual difference between them. There are normally three different structures as follows,
Optical Contact
Cemented by Epoxy
Air spaced
Low Order Waveplate
Low(multiple) order waveplate is designed to give a retardance of several full waves, plus the desired fraction. This result in a single, physically robust component with desired performance. However, even small changed in wavelength or temperature will result in significant changes in the desired fractional retardance. They are less expensive and find use in many applicatios where the increased sensitivities are not an important.
Photonchinas waveplates fabrication starts from quartz materials cutting with their axes oriented within a few arcminutes before being polished to a laser-quality finish, arcsecond parallelism, and

1200 tube furnace uses high-quality electric furnace wire as heating element, the maximum heating temperature is 1200, and the diameter of the quartz furnace tube is 50mm. If the customer needs, can contact the technician to customize the larger diameter furnace tube. The default heating zone is single temperature zone. It can also be customized according to customer needs. The temperature zone is controlled by the precision temperature control meter for PID temperature control. The 30-segment temperature rise and fall program can be edited, and the overheating and open circuit of thermocouple protection functions are also available. The flanges on both sides of the furnace tube are equipped with a digital vacuum gauge and a mechanical pressure gauge, which can be used to control the atmosphere in the furnace tube. At the same time, the tube furnace is operated by HD true color touch screen, which is easy to use. Even non-professionals can master the use of the instrument after simple training, which can greatly improve your experiment efficiency.
1200 tube furnace application range
Tube furnaces are mainly used in metallurgy, glass, heat treatment, lithium battery positive and negative materials, new energy, abrasives and other industries, and can also be used for heat treatment in atmospheric environment. It can also be used to form a CVD system for related coating test production.
