Product Description
Anti Fog Hydrophobic Endoscope Lens Waterproof IP67 Medical Rod 2.77mm
This anti fog hydrophobic endoscope lens solves one of the most persistent problems in endoscopic imaging: condensation fogging when a cold instrument enters a warm body cavity. The nano hydrophobic coating raises the water contact angle above 110 degrees, causing moisture to bead and roll off instead of forming a scattering film on the optical surface. Combined with an IP67 waterproof rating, this endoscope rod lens keeps the optical path clear through sterilization, rinsing, and immersion in cleaning solutions.
The medical rod lens is manufactured from N-BK7 optical glass with a dual-layer surface treatment: a broadband anti-reflective base coating for transmission, topped by a durable hydrophobic layer that resists abrasion and repeated wiping. The IP67 rating means the assembled optical component tolerates temporary immersion, protecting internal image quality during aggressive cleaning protocols. This anti fog endoscope lens is available in the standard 2.77mm by 29mm rod geometry and custom sizes, with coating durability verified through autoclave cycling and abrasion testing before release.

Key Advantages
- Anti fog performance keeps vision clear during temperature changes
- Hydrophobic surface sheds water droplets and cleaning residues
- IP67 waterproof rating supports immersion cleaning protocols
- AR base coating maintains high transmission with the top layer
- Coating resists abrasion from repeated wiping and handling
- Reduces procedure interruptions caused by lens fogging
- Suitable for reusable endoscope instruments and camera heads
- Coating durability validated by autoclave and abrasion testing
Field feedback from instrument service teams shows that fogging and moisture damage are among the top reasons endoscopes are returned for repair. This anti fog endoscope lens directly addresses both failure modes: the hydrophobic surface clears condensation instantly, and the IP67 waterproof construction protects the optical element when instruments are rinsed or soaked between procedures. Service life data from customer programs indicates that instruments fitted with this medical rod lens require fewer optical repairs over two years of operation. For OEMs, the coating process is fully documented and repeatable, which supports consistent quality across production batches and simplifies supplier qualification.
Product Q&A
Q: How does the anti fog coating prevent condensation?
The hydrophobic layer makes the lens surface non-wetting, so water vapor condenses into tiny beads that roll off instead of spreading into a thin film. A film scatters light and turns the image milky; beaded droplets clear quickly and keep the optical path transparent.
Q: Does the hydrophobic layer reduce light transmission?
The hydrophobic top layer is designed as a thin nano film with negligible absorption. Combined with the broadband AR base coating, the finished anti fog endoscope lens maintains transmission above 97 percent in the visible range, so image brightness is not compromised.
Q: Can the lens survive autoclave sterilization with this coating?
Yes. The dual-layer coating system is formulated for repeated autoclave exposure at 134 degrees Celsius. We validate every coating batch with autoclave cycling and tape-pull adhesion tests, and provide the test report with production shipments.
Q: Is the IP67 rating for the lens alone or the full assembly?
The lens itself is inherently moisture resistant, and the IP67 rating applies when installed with appropriate sealing in your housing. We provide installation guidance, including recommended sealants and tolerances, so your assembled endoscope achieves the rating.
