Zhongshan Pingzhi OpticsAll filters of Co., Ltd. are made of quartz. The cut-off rate of the cut-off filter can be as high as99.5% or more. The transmittance of the visible bandpass filter is higher than85%.940nmBandpassThe filter uses German coating equipment and technology, with extremely low wavelength thermal drift and extremely low time wavelength drift performance. At the same time, Shenzhen Pingzhi Optics Co., Ltd. can provide pre-delivery light intensity measurement and emission spectrum measurement services for the940nmBandpassfilter in combination with the light source.

2. Characteristics of 940nm Bandpass Filter for Optical Lenses:
Shenzhen Pingzhi Optics Co., Ltd. As a high-tech oriented optical component manufacturing enterprise, it focuses on infrared distance measuring sensors, drones. (Drone obstacle avoidance, obstacle detection) Motion recognition, LiDAR (LIDAR) has developed multiple types of ranging radar optical filters: 808nm Bandpass filter, 850nm Bandpass filter, 905nm Bandpass filter, 940nm Bandpass filter, 1550nm Bandpass filter and other optical filters. For the R & D of LiDAR (LIDAR), we have also carried out customized production cooperation with many optical teams, and can carry out targeted production and R & D according to different optical optical filter requirements.
The main function of a bandpass filter is to allow light of a specific wavelength to pass through and reflect (or attenuate) light of other wavelengths. It is an optical component. The half - wave width is usually controlled within20nm or less, and it can cover ultraviolet, visible, near - infrared, and far - infrared wavelengths.. The narrow - band filters of Shenzhen Pingzhi Optics Co., Ltd. are made by ion - assisted deposition of nano - materials in high - vacuum evaporation of multi - layer hard films. The film layer has good compactness and high imaging clarity.
