Key Features
-
450nm Optimized Design
Precision-engineered for blue light transmission (420-480nm), maximizing sensitivity in turbid water and low-light conditions. -
Large Aperture & Compact Form
≥200mm entrance aperture captures 58% more photons than standard 160mm lenses, while maintaining ≤1000mm total optical length for submersible system integration. -
Wide-Angle Surveillance
20° full FOV (diagonal) enables broad-area monitoring with 12MP resolution at 5m working distance. -
Focal Precision
191.799mm (±0.05mm) calibrated focal length @450nm ensures <3μm spot size for scientific-grade imaging.
