LIDAR Applications

Infrared (IR) filters for portable or airborne LIDAR devices (1064 & 1550 nm), e.g laser rangefinders.

LIDAR applications


The infrared LIDAR (Light Detection And Ranging) technology uses infrared light to detect and register objects. The remote sensing technology illuminates a target with laser light and analyzes the reflected light.

LIDAR technology is applied in portable or airborne devices to create high resolution maps, remote sensing, and laser altimetry, among other. LIDAR is for instance applied in laser rangefinders.

Laser rangefinders are often portable and used outdoor in all weather. In this type of application a filter (also called cover lens) can function as an additional protection of the sensitive optical components. Therefore, such devices often need to be scratch- and impact resistant, light weight, and hydrophobic. A hydrophobic topcoat repels (rain)water so droplets run of very easy. This ensures minimum signal distortion in both emitters and detectors.

Near infrared optical filter solutions for LIDAR


Our cast acrylic filters combined with our optimised 1550 AR surface treatment result in excellent filter solutions for LIDAR applications which apply the 1550 nm infrared light, e.g. eye-safe laser rangefinders.

For LIDAR applications, which apply 1064 nm infrared light, our Solaris S306 IR (with or without NIR AR) is the perfect solution.

Typical display window requirements
