Confirm exact article, revision and supplied condition before orderingDescription:
high-resolution low-distortion 8 mm lensMatch the 8 mm field of view, C-mount interface, 2/3-inch image limit and required close-up ring. For CV-020, CV-070, CV-035C/M and CV-H035C/M use, the manufacturer notes a close-up ring at least 1.5 mm thick.
Engineering note: Archive the validated focus, aperture, working distance and inspection image after optical alignment.
Installation planning
Confirm CA-LH8 enclosure protection, cabinet heat dissipation, mounting arrangement and documented environmental limits before installation.
Storage and handling
Keep CA-LH8 protected from moisture, contamination, impact and electrostatic discharge from receipt through installation.
Send the exact CA-LH8 model, required quantity, destination and installed hardware details. Request current nameplate photographs and confirm compatibility before ordering.
Use CA-LH8 for wide machine-vision views where an 8 mm focal length and controlled geometric distortion suit the inspection area.
Choose the lens from sensor format, field of view, working distance and mounting constraints rather than focal length alone.
Lifecycle assessment: Confirm current availability and lifecycle status against the latest manufacturer notice for the exact article number.
Ordering check: Verify the full model, article number, hardware revision and supported project release before purchasing.
Complete these six checks against the current project documentation and the official exact-model record.
Use the exact lens record and the inspection drawing to establish the optical setup.
Record focus position, aperture, lighting and a reference image for later maintenance.
The exact lens specification lists an 8 mm focal length. Confirm the resulting field of view at the real camera distance.
CA-LH8 uses a C-mount. Inspect both threads and keep the camera sensor cover clean during installation.
The manufacturer specifies a maximum compatible image size of 2/3 inch.
The aperture range is F1.4 to F16. Set it together with exposure and illumination to meet depth-of-field and brightness needs.
The official value is 0.1 m. Verify focus and framing on the actual inspection target.
The model uses a 27.0 mm P0.5 filter thread. Confirm accessory clearance before fitting a filter.
For use with CV-020, CV-070, CV-035C/M or CV-H035C/M, the manufacturer notes a ring at least 1.5 mm thick.
TV distortion is listed as -0.6%; the parenthetical -0.28% value applies to the referenced 1/3-inch image condition.
Keep the lens from 0 to 50 deg C and at 80% RH or less without condensation.
Provide CA-LH8, camera model, sensor size, working distance, required field of view, quantity, destination and clear lens-label photographs.
