Micro-optics enable low-distortion wide-angle endoscope imaging at submillimeter sizes; collimating lenses support OCT beam focusing and scanning. Hemispherical lenses homogenize cavity illumination. Square collimating lenses fold paths for thinner endoscope probes. Ball lenses deliver cellular resolution for confocal microendoscopy.

Laser Therapy

Collimating lenses (square, C-lenses) deliver precise targeted laser from therapeutic fibers. Micro-optics focus micron-scale spots for tissue ablation in dermatology and ophthalmology. Ball lenses enable fine microsurgical laser operations; hemispherical lenses homogenize beams for uniform photodynamic therapy.

Optical Diagnostics

Hemispherical lenses and micro-optics optimize illumination and collection in fundus cameras and dermatoscopes, revealing microvasculature and lesions. Collimating lenses enable confocal scanning ophthalmoscopy with enhanced contrast. Square collimators correct astigmatism; ball lenses enable non-invasive deep ENT observation.

Optical Sensing

In pulse oximeters, hemispherical lenses homogenize LED light; ball lenses focus returns to detectors for continuous heart rate and SpO₂ monitoring. Micro-optics couple fiber-tissue light for non-invasive deep tissue sensing. Collimating lenses align red/IR beams to boost oximetry SNR.

Fluorescence Imaging

Micro-optics (ball, collimating lenses) enable excitation focusing and emission collection in fluorescence microscopes, visualizing tumor markers and molecular distributions. Ball lenses enable large-field mucosal excitation in endoscopic probes. Collimating lenses paired with filters boost detection SNR and multi-label imaging quality.

Spectral Analysis

Raman fiber probes use micro-optics and collimating lenses for label-free rapid tissue chemical analysis. Hemispherical contact interfaces reduce skin reflection and boost SNR. Square collimators in SORS probes separate superficial/deep signals for non-invasive deep tissue analysis and tumor margin assessment. Ball lenses enable miniaturized probes for in-situ endoscopy spectral analysis.
