Micro-optics are revolutionizing healthcare by enabling advanced diagnostic, therapeutic, and imaging technologies. These precision components are integral to devices such as endoscopes, optical coherence tomography (OCT) systems, and wearable health monitors. In diagnostics, micro-optics enhance imaging resolution and light delivery, allowing for detailed visualization of tissues and early detection of diseases. For minimally invasive procedures, they enable compact and precise optical systems that improve surgical outcomes and patient comfort. In therapeutics, they are used in laser-based treatments for targeted and efficient interventions. By integrating micro-optics into healthcare technologies, medical professionals can achieve greater accuracy, efficiency, and accessibility in patient care.
