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.

In order to strengthen the management of labor protection appliances, improve the operating conditions of construction workers, and prevent the occurrence of production safety accidents, the Bazhou Safety Production Supervision Bureau decided to administer the labor protection products of the production and business units of the entire state from August 4 to September 15. , use of supervision and inspection.
The focus of this inspection is on chemical and construction enterprises, metallurgy and manufacturing and processing enterprises in safety helmets, safety belts, safety nets, protective masks, dust masks, gas masks, special work clothes, safety shoes (boots) and other labor protective products. Configuration situation. The contents of the inspection are mainly whether the production and business operation unit equips the employees with labor protection articles according to the national, industry or local standards, and whether the safety protection performance of the labor protection articles complies with national standards or industry standards.
Through this inspection, the purpose is to urge enterprises to establish a series of management systems for the procurement, acceptance, storage, distribution, use, and retirement of labor protection products, and to effectively protect the legitimate rights and interests of workers.
