Frequently Asked Questions
Q: Why is geometric distortion control so critical in this Manual Focus M58 Mount 0.08% Distortion Line Scan Lens?
A: In dimensional measurement applications, any lens distortion introduces pixel displacement at the edges. This manual focus M58 mount 0.08% distortion line scan lens limits distortion to -0.08%, ensuring that physical measurements calculated via software remain precise across the entire line scan array.
Q: How does the manual focus system hold up under continuous factory vibration?
A: The manual focus 0.08% distortion line scan lens is equipped with heavy-duty mechanical locking screws on both the focus and aperture rings to eliminate drift.
Q: What line scan camera sensors can I pair with this M58 mount line scan lens?
A: It perfectly supports Φ30mm image formats, including 4K line sensors with 7μm pixels and 8K line sensors with 3.5μm pixels.
