Optical Infrared Bandpass Filter 780nm For Remote Sensing

The optical Infrared bandpass filter 780nm combines absorption and reflection to selectively transmit the desired wavelengths around 780 nanometers to pass through while blocking or attenuating other wavelengths outside this range. It is commonly used in various applications, such as remote sensing, surveillance, and machine vision.

Our filter typically consists of a thin layer of material, such as glass or plastic, coated with a particular dielectric material to achieve the desired transmission characteristics. We take the pride in our outstanding products---high transmission rate, ultra-narrowband, great durability, and we can provide the most suitable optics solution by customizing your filter's design and construction according to its peak transmission, bandwidth, and blocking efficiency.

- Remote Sensing

- Spectroscopy

How does IR 780nm bandpass filter apply in remote sensing?

Optical Infrared bandpass filter 780nm allows remote sensors to capture light in the near-infrared (NIR) region of the electromagnetic spectrum. This range of wavelengths is beneficial for remote sensing because it is sensitive to the reflection and absorption of light by vegetation and other natural features on the Earth's surface.

By capturing data in the NIR range, remote sensors can detect subtle differences in the reflectance properties of plants and other vegetation, which can be used to monitor crop health, track changes in land cover, and even estimate biomass and carbon storage. Additionally, the 780nm IR bandpass filter can be used in atmospheric remote sensing to measure the concentration of gases such as carbon dioxide and methane, which have absorption features in this wavelength range.
