Request InfoKnight OpticalKnight Optical LLC has announced a range of stock Achromatic Doublet Lenses for use within wind lidar. Achromatic doublets correct for chromatic aberrations that exist in singlet lenses when different wavelengths of light refract at different rates. The doublet lens helps to correct this by facilitating the focusing of the light to the same point. In wind lidar, a system of doublet and aspheric lenses are typically used to shape the light by focusing highly divergent rays, potentially replacing a multilens system, providing better signal quality at lower costs with a smaller footprint....See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra September 2022 IssueDirect Time-of-Flight SensorThe VL53L8 direct Time-of-Flight sensor from STMicroelectronics can be used for smartphones, smart speakers, human-machine interfaces, consumer lidar, augmented reality, and more.
