China star optics can provide customers with a variety of replicated grating products such as diffraction gratings, reflective gratings,holographic gratings,concave gratings etc. to meet different needs. Maximum ruled area is up to 300x300mm2 for plane ruled diffraction gratings. For replicated diffraction and transmission gratings the ruling density can be from 20 grooves per millimeter to 2400 grooves per millimeter, wavelength from 0.2 micron to 25 microns.
They are widely used for applications in optical communications,biotechnology, colorimetry,chromatography,and medical instrumentation.
Handling Gratings: Gratings require special handling, making them prone to fingerprints and aerosols. Gratings should only be handled by the edges.

Since many products use materials such as alloyed copper, their prices have also increased. Non-ferrous metals related industries mainly include power grids (wires and cables, power supplies), white goods (air conditioners, refrigerators, and washing machines), transportation (ships, automobiles, etc.), electronic products, buildings (communication cables, residential electrical lines, etc.), and others ( Mechanical engineering, metallurgical equipment, alloy additives, etc.) Five categories. In July, ex-factory prices of copper and other non-ferrous metals products rose. The ex-factory price of split-type room air-conditioning products in the white goods industry increased by 0.6% month-on-month; prices of the five kinds of power grid products rose by 0.3%-1.4%.

Non-ferrous metal product prices increase in chain prices to boost appliance prices
According to data released yesterday by the Shanghai Bureau of Survey of the National Bureau of Statistics, the prices of the non-ferrous metal products manufactured and purchased in the city increased by 1% and 2.3% month-on-month, respectively, in July, and the increase rate increased compared with June. The ex-factory price of non-ferrous metal products rose month-on-month. Up to Liu Cheng.
