This M18-interface "pocket powerhouse" packs 2 glass lenses + 4 plastic aspherical lenses (2G4P) into a total length of 18mm, achieving <-0.2% ultra-low distortion and an 82° wide viewing angle. It solves industrial pain points like "blurriness, measurement inaccuracy, and space constraints"!

I. Three Cutting-Edge Technologies for Industrial "Perfectionism"

1. Negligible Distortion (<-0.2%)

What does this mean?

Ordinary lenses turn straight lines at edges into "bananas" when capturing grid paper. With JSD9928, edge errors on a 10cm scale are <0.2mm (thinner than a human hair). PCB solder joint measurements skip software correction, reducing misjudgments by 90%.  

Secret weapon: Four plastic aspherical lenses "knead" light like dough, flattening edge distortion!

2. 18mm Slim Design, Space-Saving Expert

Vs. competitors: Traditional industrial lenses are ≥25mm long. JSD9928 is as tall as a bottle cap (18mm), fitting into surgical robot joints, AGV heads, or drone gimbals.

Optical magic: A front negative lens expands the field (radius R=-1.2mm), while a rear positive lens suppresses aberrations—like fitting a telescope into a matchbox!

3. F2.8 Night Vision + 1/1-Inch Large Sensor

Low-light killer: The 1/1-inch sensor offers 70% larger light intake than common 1/2.7-inch sensors. Paired with F2.8 aperture, noise stays <30dB at 0.01 Lux—inspecting underground pipes requires no extra lighting; rust and cracks are crystal clear.

Thermal stability: Focus drift <2μm from -30°C freezers to 85°C workshops (equivalent to sharp focus from Everest to deserts!).

II. Real-World Scenarios: Precision Meets Space Challenges

1. Semiconductor Wafer "Flaw Detector"

Covers an 8-inch wafer at 30cm distance with its 82° view. <-0.2% distortion ensures <0.07μm error in measuring 3μm linewidths—like engraving on an ant’s antenna and verifying each stroke!

Cost saver: Replaces "lens + correction algorithms," eliminating GPU needs—runs on tiny ARM chips.

2. Medical Endoscope "Microscopic Eye"

Fits into 3mm-diameter tubes at 18mm length. A 51.4° vertical view covers gallbladder surgery zones (8×6mm²), boosting vessel/nerve separation by 50%—stays clear even if a surgeon’s hand shakes.

Biocompatible: Direct tissue contact? Certified by ISO 10993.

3. Drone Power Inspection "Anti-Shake Master"

Weighs just 22g (with M18 interface), barely affecting drone payloads.

71.7° horizontal view tilts to shoot power lines; 51.4° vertical view prevents missed defects. Spots 0.5mm cracks on insulators from 100m high—10x faster than manual tower climbs.
