We provide customized optical filter solutions for all your lidar applications.
Lidar — an acronym for light detection and ranging — is a remote sensing technology that uses light pulses to get information about surrounding objects. Historically, lidar systems have been used for surveying equipment, satellites, and specialized photography. Today, they’re commonly used for consumer devices, like self-driving cars, smartphones, and even vacuum cleaners.
Stray and ambient light can make it difficult for lidar systems to acquire a signal in any application. You can distinguish between lidar wavelengths and other light sources with an optical filter from Salvo Technologies.
We carry numerous types of bandpass filters — also known as thin-film interference filters — for lidar applications, including:
Our lidar filters offer many essential benefits. They have durable, multilayer hard coatings, enabling them to withstand the harsh environmental conditions characteristic of many lidar applications. They’re also virtually absorption-free, providing high transmission over ultranarrow bandwidths and deep out-of-band blocking over larger wavelengths.
Our lidar filters also have steep edge transitions between the high transmission bandpass and the longer and shorter wavelength reflection bands — significantly steeper than polymer gels and colored glass.
Other lidar filter features and benefits include:
You can use our specialty optical filters for numerous lidar applications, including:
We provide custom filters to meet all your application requirements. We match your specific bandwidths and cut-on/-off wavelengths to isolate your lidar return signal with less background. We’ll also configure our solutions to your unique shapes and sizes, with custom coating options available.
