Frequently Asked Questions

Q: What is the focal length of this M8.2 lens?
A: The lens has a fixed 4.8mm focal length. It is designed for compact imaging systems requiring a relatively broad field of view without using a zoom mechanism.

Q: What sensors are compatible with this 4.8mm lens?
A: The specified image formats are 1/2.3″ and 1/2.5″. The lens provides different FOV values depending on the sensor format.

Q: What is the FOV on a 1/2.3″ sensor?
A: On a 1/2.3″ sensor, the lens provides 78° diagonal, 66° horizontal, and 52° vertical FOV.

Q: What is the distortion of this lens?
A: The specified TV distortion is below 1%, making it suitable for applications where maintaining accurate image geometry is important.

Q: Is this an M8 miniature lens?
A: Yes. The lens uses an M8.2 × 0.25 mount and fits within TOWIN’s miniature small-mount lens product family. It is suitable for compact camera and embedded imaging applications.

Q: Is this lens suitable for machine vision?
A: Yes. Its 12.3MP resolution, <1% distortion, F1.8 aperture, and compact M8.2 mounting make it suitable for compact machine vision and automated inspection systems.

Q: What is the minimum object distance of this lens?
