Environmentally friendly household building materials consumption is booming and gradually forming new hot spots

He published the "2013 China Economic Review" series of reports, in the second "New Progress in Structural Adjustment" mentioned that the 1 minute Alipay transaction amount exceeded 100 million yuan, less than 6 hours of sales exceeded 10 billion yuan mark, 13 hours More than the previous year's sales... 2013 "Double 11", Tmall Alipay turnover reached 350.19 billion yuan, refreshing the record of 19.1 billion yuan set last year, this day became the "carnival" of e-commerce, and believe that domestic Demand dynamics are abundant, consumer market highlights are frequent, and demand structure is further improved. The article pointed out that last year, China's demand structure was further improved. The outstanding performance was that domestic consumption was slowing down, stable and stable, and the highlights were frequent. In addition to the “blowout” growth of online consumption, consumption of smart phones and smart TVs was very active. Consumption of energy-saving cars and environmentally-friendly home building materials has grown rapidly. Shen Danyang, a spokesperson for the Ministry of Commerce, said that this marks a new generation of consumer hotspots.

300mm Diameter Dome Lens

Our Dome Lens is an optical window composed of two parallel curved surfaces. Dome lenses are commonly used in meteorology applications, pyranometers, defence applications and often used in high pressure viewports in underwater cameras and submersibles.For this reason our dome offer both high transmission as well as durability. Other application for our dome include visible-range domes for pyranometers and infrared-range domes for pyrgeometers, and as high pressure viewports in underwater cameras and submersibles.

BK7 or K9L domes are used primarily in meteorology applications. BK7 offers excellent transmission from 300nm up to 2µm. BK7 is a relatively hard material, with excellent chemical durability.
UV fused silica domes ( JGS1 ): For applications operating in the deeper UV range, we offers a range of UV fused silica domes. Fused silica domes are commonly used in underwater applications at extremely high pressures.
Sapphire domes: For infrared applications we can provide sapphire domes. Sapphire is an extremely hard material with transmission of over 80% in the 2-5µm wavelength range. As with fused silica, sapphire is able to withstand extreme pressures, making it the perfect material for underwater camera and missile fairing applications.
