Focus on spectral sensing and optoelectronic application systems
Laser Far-Field Measurement System
With the development of IoT, AI, and 5G technologies, VCSEL (Vertical Cavity Surface Emitting Laser) technology, as a core technology of 3D imaging and sensing systems, is increasingly gaining attention in applications such as facial recognition, 3D sensing, autonomous driving, gesture detection, and VR (Virtual Reality)/AR (Augmented Reality)/MR (Mixed Reality).
LiSen Optics can provide customers with VCSEL/VCSEL-3D SENSING/TOF detection solutions, including LIV spectrum/power integration testing, NF near-field characteristic testing, FF far-field characteristic testing, BRDF/BTDF optical material AR/VR characteristic testing, and VCSEL-specific integrating spheres. These solutions enable the measurement of energy distribution and uniformity, spectral wavelength and power, near-field and far-field measurements for VCSEL/Mini LED/Micro LED devices, modules, and wafer chips to meet various customized application needs.

Product Introduction
The LS-VCS-FF far-field testing system, developed by LiSen Optics specifically for VCSEL far-field testing, can measure the far-field divergence angle and spatial energy distribution of the beam, thereby calculating the beam collimation and symmetry. It can also measure the energy density of the beam at different distances for laser safety evaluation.
