900nm-1575nm Infrared Bandpass Filters for Wide Angle Laser Ranging And Radar System

Wide Angle Laser Ranging And Radar System Filters 900nm, 905nm, 1064nm, 1550nm, 1575nm IR Bandpass Filter

The main function of narrow-band filters and bandpass filters is to transmit a specefic wavelength of light through an optical element, allowing the reflection (o attenuation) of other wavelengths of light. Half wavelengths are usually controlled above 4-20nm or 20-70nm and can be ultraviolet visible near infrared and far infrared wavelengths.

Our narrow band filters are made from ion-assisted deposetion of nanomaterials and high vacuum evaporation of multilayer hard films. It has the characteristics of good film density, wide cutoff range, high cut-off depth, high transmittance, hard coating, long service life, accurate wavelength positioning, low temperature drift, good penetration and high imaging clarety.

Wide-angle and deep-cut near-infrared bandpass filters, which are key components in rangefinder and lidar systems. The product has extremely high transmittance and good signal-to-noise ratio at laser and LED output wavelengths.

Advantages:

1.High transmittance

2.Deep cut-off

3.High steepness

4.Wide incident angles

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.
