We are also supplying quartz plate, quartz apparatus and some section quartz tube such as u shape, helical quartz tube, v shape and etc. We can also make the quartz tubes cut, bended, frosted, domed and glazed.
With the adoption of distinctive technique, our opaque quartz glass tube has its typical characteristics of good visual aspects and stable physical &chemical properties. It serves as material of infrared heating for heaters, micro-wave oven, electrical baking oven, car paint baking, sterilization container and other consumptive and industrial infrared application. Further processing of trim cutting, bowing, fire-polishing can be done according to the demanding of the customers.
Dark-red and golden quartz tube is a new kind of quartz material. Compared with common transparent quartz, it can absorb uv and most visible light and translate into infrared radiation. Compared with milk-white quartz, it can penetrate infrared radiation, which can load several times of energy per area. Compared with coated quartz, it is low-cost and high-stability. So it is an excellent material for producing infrared heater. Ití»s suitable for high-power and small-volume infrared heating products.

Quartz is a chemical compound consisting of one part silicon and two parts oxygen. It is the most abundant mineral found at Earths surface and its unique properties make it one of the most useful natural substances.Quartz is the second most common mineral in the Earths continental crust. It is made up of a lattice of silica. Its usefulness can be
linked to its physical and chemical properties. It is chemically inert in contact with most substances. It has electrical properties and heat resistance that make it valuable in electronic products. Its luster, color and diaphaneity make it useful as a gemstone and also in the making of glass. This makes it a very essential mineral in our daily life.
Quartz compound consists of one part silicon and two parts oxygen i.e. Silicon dioxide (SiO2). The atoms are linked in a continuous SiO4 Silicon. Oxygen Tetrahedral framework. Quartz exists in two forms, the normal + -quartz, and the high-temperature quartz, both of which are chiral.
Pure quartz, traditionally called rock crystal or clear quartz, is colorless and transparent or translucent and has often been used for hardstone carvings. Common colored varieties include Citrine, Rose Quartz, Amethyst, Smoky Quartz, Milky Quartz, and others.
These color differentiation arise from chromophores which have been incorporated into the crystal structure of the mineral.

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
