ACTUAL APPLICATIONS
Application context for CA-LH8
Manufacturer documentation places the Low-Distortion Machine Vision Lens in practical generic applications. The three cases below describe different operating tasks in which CA-LH8 performs its documented product-family role with the configured companion equipment.
- 01 · POWER GENERATION
Integrate generator excitation with Low Distortion
At the control layer of the field circuits and voltage regulation, CA-LH8 performs its assigned control role as a Low-Distortion Machine Vision Lens. During load change, the system uses this function to adjust the assigned regulation path from operating feedback, helping it hold the electrical variable at its commanded target. - 02 · AUTOMOTIVE
Synchronize body transfer with Low Distortion
During operation of the skid conveyors and lift stations, CA-LH8 provides its specified system function as a Low-Distortion Machine Vision Lens. During model change, the system uses this function to coordinate motion requests and station interlocks, helping it keep the assembly takt moving. - 03 · WATER & WASTEWATER
Protect raw-water pumping with Low Distortion
Across the intake pumps and wet wells, CA-LH8 operates in its approved product-family role as a Low-Distortion Machine Vision Lens. During peak-flow demand, the system uses this function to coordinate pump duty and level response, helping it maintain hydraulic continuity.

VISION LENS INTEGRATION
Confirm sensor format, working distance and image circle
KEYENCE CA-LH8 is an 8 mm high-resolution, low-distortion C-mount lens designed for image sensors up to 2/3 inch.
Integration depends on the connected camera sensor, required field of view, 0.1 m minimum working distance, aperture setting, filter clearance and illumination.
For the listed compact CV camera models, add a close-up ring of at least 1.5 mm as specified by KEYENCE, then verify focus and edge resolution.
Features:
- 8 mm focal length with C-mount
- F1.4 to F16 manual aperture
- 100 cycles/mm center resolution
The KEYENCE CA-LH8 lens requires the camera sensor, working distance, close-up-ring condition and optical setup to be confirmed before system integration.
OPTICAL INTERCHANGEABILITY
Match geometry and imaging performance before exchange
Replace CA-LH8 with the same lens when the validated inspection depends on its 8 mm focal length, 2/3-inch sensor coverage and low-distortion characteristics.
Before removal, record aperture, focus position, extension adjustment, filter or lighting attachment, working distance, camera orientation and calibration data.
A different 8 mm C-mount lens can change distortion, resolving power, barrel clearance and field of view; repeat calibration rather than assuming a direct optical match.
Features:
- Confirm exact CA-LH8 lens identity
- Retain aperture, focus and extension settings
- Recalibrate field of view and edge geometry
The KEYENCE CA-LH8 requires replacement verification through focus, distortion, field-of-view and inspection-repeatability testing.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about CA-LH8
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
What field of view does CA-LH8 provide?
The 8 mm focal length gives a relatively wide view; the actual field depends on sensor size, working distance and camera resolution. -
Which camera mount is used by the CA-LH8 lens?
It uses a standard C-mount and is specified for image sensors up to 2/3 inch. -
How close can the lens be positioned to the target?
KEYENCE specifies a minimum working distance of 0.1 m; maintain at least that optical distance during setup. -
How is image brightness adjusted on CA-LH8?
Set the manual aperture between F1.4 and F16, then balance exposure and illumination on the connected vision controller. -
What resolution does the lens support?
KEYENCE specifies 100 cycles/mm at the center and 80 cycles/mm at the image periphery. -
When are close-up rings required with this lens?
CV-020, CV-070, CV-035C/M and CV-H035C/M applications require close-up rings at least 1.5 mm thick. -
What must be checked before replacing another 8 mm lens?
Compare C-mount, sensor format, aperture, working distance, filter thread, distortion and available mechanical clearance. -
How should a CA-LH8 installation be validated?
Refocus at the production distance, set aperture and lighting, then check edge sharpness, distortion and inspection repeatability across the full image.
