This week, the domestic solar wafer market went down and the international wafer market continued to decline. According to Polaris Solar Photovoltaic Network, domestic single-crystal 6.5-inch wafers are quoted at 5.0-5.6 yuan per wafer, 8-inch silicon wafers are quoted at 8.7-9.2 yuan per wafer, down 0.2 yuan per wafer; polycrystalline 8-inch silicon wafers The price was maintained at RMB 6.8-7.4/tablet, a decrease of RMB 0.1-0.2/piece. In addition, the international polysilicon chip market price: 156mm × 156mm for the 1.00-1.20 US dollars / piece, the average price of 1.036 US dollars / piece, a drop of 0.38%; single crystal silicon wafer: 156mm × 156mm is 1.25-1.50 US dollars / piece, the average price of 1.308 yuan / Tablets, a decrease of 0.91%; 125mm × 125mm is 0.70-0.84 US dollars / piece, the average price of 0.740 US dollars / piece, a decrease of 0.67%.
According to Polaris Solar PV Network, the domestic silicon wafer market continued to decline slightly, and overall transactions slowed down. The monocrystalline silicon wafer market has been steadily declining. The quotation is still confusing. The purchase price of a 6.5-inch A-chip is less than 5.0 yuan per piece. Some manufacturers are reluctant to ship in the face of current low prices and are not willing to ship. They continue to choose to wait and see. At the same time, with the increase in production of polysilicon wafers in recent months, the supply of the market has increased significantly, resulting in the price of the polysilicon wafers running at a small drop. Although many companies have adopted cost reductions and increased market competitiveness in terms of quality, the trend of silicon wafers is still worrying in the short term due to the weak demand from end-users.

An optical prism is a transparent optical element with flat, polished surfaces that refract light.
Reflective prisms are used to reflect light, in order to flip, invert, rotate, deviate or displace the light beam. They are typically used to erect the image in binoculars or single-lens reflex cameras – without the prisms the image would be upside down for the user. Many reflective prisms use total internal reflection to achieve high reflectivity.
The most common reflective prisms are:
Porro prism
Porro–Abbe prism
Amici roof prism
Pentaprism and roof pentaprism
Abbe–Koenig prism
Schmidt–Pechan prism
Bauernfeind prism
Dove prism
Retroreflector prism
Beam-splitting prisms
Some reflective prisms are used for splitting a beam into two or more beams:
Beam splitter cube
Dichroic prism
Half Penta Prism,Penta Prisms,Dove Prism,Optics Prism
