650nm Short Pass Optical Filter High Transmittance For Face Recognition System

High Transmittance 650nm Short-wave Pass Filter

650nm short-pass filter is also called IR650nm filter, the main optical characteristics are visible band transmittance can reach more than 90%, infrared band area cut-off, according to customer needs can do infrared cut-off OD1-OD6 different requirements. So there are many customers to 650nm band short-wave pass filter is also called infrared cut-off filter. Widely used in beauty instruments, strong flashlight stage lighting color, face recognition system, optical instruments, optical fiber lighting, cold light display cabinets, police multi-band testing equipment, etc

Through the region 400-650nm, cut-off depth OD4-OD6

Founded in 2001, Beijing jinji'aomeng Technology Co., Ltd. is the first professional coating company in China, which was reformed from Beijing Jingnan Applied Technology Research Institute, which was founded in 1993. The company is the earliest private optical coating manufacturer.

The company bought land in Zhongguancun Science and Technology Park in Beijing and built a high-grade optical coating plant of more than 4000 square meters.

The founder of the company is a senior optical coating expert in China. Nine optical coating systems have won the science and technology progress award of the people's Republic of China. He has been engaged in military optics research for close to 50 years and is one of the most senior coating expert in the world.

The company has 13 sets of optical coating machine. Including two sets of German Laibao company high precision advanced coating machine.

In order to ensure the cleaning of coated substrate, the company has 13 tank ultrasonic cleaning machine.

The company's coating test instruments have high precision and large quantity.

The company has passed the ISO9001 international quality,management system,the optical coating and filter products provided by the company are excellent in quality, reasonable in price, timely delivery.
