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.
