Rod lenses are the core optical elements in rigid endoscopes such as laparoscopes, arthroscopes, sinuscopes and cystoscopes. They transmit optical signals and form images, directly affecting the brightness, contrast and color fidelity of endoscopic footage.
We offer custom manufacturing services for medical-grade rod lenses:
? Substrate options: N-BK7, H-K50 and other medical optical glass, compatible with repeated autoclave sterilization
? Ultra-precision polishing on plane or spherical ends to minimize scattering and optical loss
? Anti-reflection (AR) coating available to reduce reflection, suppress chromatic aberration and support HD / 4K imaging
? Custom outer diameter, length and curvature to fit rigid endoscopes of 0°, 30°, 70° field of view
? Full optical inspection with dimension, surface figure and transmittance test reports, stable mass delivery We serve endoscope manufacturers and optical solution providers.
Both prototype sampling and long-term OEM volume supply are supported. Please send your optical drawings for evaluation and sample quotation.
