Product Description
F2.0 Large Aperture 4K 8K Line Scan Lens
The F30M5020M42 is an ultra-fast, high-sensitivity F2.0 Large Aperture 4K 8K Line Scan Lens engineered specifically for low-light environments and ultra-high-speed industrial processing lines. Featuring a 50mm focal length, this lens stands out by offering a massive F2.0 maximum aperture, allowing twice as much light transmission compared to standard F2.8 lenses.
Optimized for Φ30mm sensors, this 4K 8K line scan lens delivers exceptional clarity, a flat field, and an incredible Relative Illumination profile (>90%), minimizing data noise in demanding machine vision applications.

Frequently Asked Questions
-
What makes an F2.0 Large Aperture 4K 8K Line Scan Lens better than an F2.8 lens for high-speed scanning?At ultra-high line rates, camera exposure times drop to microseconds. An F2.0 large aperture 4K 8K line scan lens gathers double the light of an F2.8 lens, meaning you can maintain low sensor noise and avoid expensive, overly powerful external strobe lighting.
-
Does this 4K 8K line scan lens maintain sharpness when wide open at F2.0?Yes, this F2.0 large aperture line scan lens utilizes specialized high-refractive-index glass elements to maintain excellent MTF contrast and sharpness even at full F2.0 aperture.
-
Can I customize the filter size or mechanics for this line scan lens?The lens comes with a standard M43 P=0.75mm filter thread and can be adapted with custom step rings based on specific OEM system requirements.
