FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How can a buyer confirm that CA-LH8 is the right lens for an existing KEYENCE camera?
Check the exact camera model, sensor format, C-mount interface, required field of view, working distance, and illumination before selecting the lens.
Which accessories should be confirmed separately when ordering CA-LH8?
Confirm whether filters, close-up rings, protective optical accessories, camera cables, lighting, and mounting parts are required because they are not assumed to be included.
When should CA-LH8 be compared with another CA-L Series lens?
Compare alternatives whenever the required field of view, target size, camera sensor, working distance, or installation space differs from the validated setup.
Can CA-LH8 be fitted to any C-mount camera without further review?
No. A matching mount alone does not prove optical compatibility; sensor coverage, field of view, working distance, resolution, and mechanical clearance must also be checked.
What should be revalidated when CA-LH8 replaces an existing lens?
Recheck focus, aperture, distortion, field of view, lighting, calibration, inspection thresholds, and physical clearance using qualified production samples.
Does CA-LH8 always fit without a close-up ring?
No. KEYENCE lists close-up-ring conditions for certain cameras, so the exact camera and working distance must be checked.
What must be confirmed before ordering CA-LH8?
Confirm the camera model, sensor size, required field of view, working distance, mount, filter, and any close-up-ring requirement.
