Description

1.Working principle
**0nm bandpass filter mainly by means of infrared **0nm LED, **0nm semiconductor laser, infrared light source and other various infrared light source to stimulate (emission), the light is reflected back through the **0nm filter to eliminate or filter out stray light, ensure that the received signal is accurate, and will not come out distortion or saturation and garbled phenomenon. Achieve a large amount of data collection and transmission.

2.Filter advantages:
1) Suitable for sunlight and other bright light interference work;
2) Transmittance up to *0%, and the optical signal attenuation rate is small, effectively improve the working distance and light intensity; 
3) Can be directly coating or glue in the infrared transmittance glass by the visible light, rapidly increase the cutoff rate, the vertical incidence in strong light without penetration, light transmission rate is less than 0.2%. And to ensure that working in large angle,and short wavelength shift phenomenon reduction.
4) More than *0 years experience in the production of optical filter, imported coating machine to produce, IAD ion assisted deposition technology and to ensure that the low temperature drift and film firmness stronger.

The specification is :
