Aven Tools 26700-181 Computar MLH Manual Zoom C-Mount Lens
Aven Tools 26700-181 Computar MLH Manual Zoom C-Mount Lens
The Aven 26700-181 Computar MLH lens provides manual zoom, iris and focus adjustment for inspection, machine vision and robotics applications requiring a variable angle of view. Its C-mount connection supports integration with compatible imaging equipment, subject to sensor and mechanical-fit verification.
At an inspection station, adjust the view to frame the part, then set focus and iris for the imaging task. Aven describes a 10X manual zoom; this refers to the zoom capability, not a fixed 10X displayed image magnification.
Best Uses / Applications
- Inspection setups requiring a variable angle of view.
- Machine-vision applications with compatible C-mount imaging equipment.
- Robotics imaging where manual optical setup is appropriate.
- Bench imaging tasks requiring independent manual iris, focus and zoom controls.
Key Features
- Manual zoom, focus and iris controls.
- Manufacturer-listed 10X manual zoom.
- C-mount connection.
- Manufacturer-listed focus range of 0.15–0.45 m.
- Variable viewing angle; sensor format affects field of view.

Manufacturer source discrepancy: Aven's product header identifies SKU 26700-181, while the supplied optical-data table labels its model 26100-181. The optical values above are reproduced from that supplied table and require manufacturer confirmation if they are critical to system design. This listing retains the product-header SKU; it does not treat the two numbers as verified interchangeable models.
Angle of View by Sensor Format
Reference values from the supplied optical table, subject to the model-number clarification above. D = diagonal, H = horizontal, V = vertical.
| Sensor format | Diagonal | Horizontal | Vertical |
|---|---|---|---|
| 1/2 type | 21.6°–4.5° | 18.0°–3.6° | 13.8°–2.7° |
| 1/3 type | 17.0°–3.3° | 13.8°–2.7° | 10.6°–2.0° |
| 1/4 type | 13.0°–2.5° | 10.6°–2.0° | 8.0°–1.5° |
Manual Zoom vs. Fixed Viewing Setup
| Approach | Selection consideration |
|---|---|
| Computar MLH manual zoom lens | Adjust viewing angle, iris and focus manually to suit the task |
| Fixed viewing configuration | Select a preset framing arrangement when adjustable zoom is not needed |
A C-mount interface alone does not establish complete compatibility. Verify sensor format, required field of view, mounting arrangement and operating distance before integrating the lens.
Frequently Asked Questions
What is Aven 26700-181?
It is Aven's listed Computar MLH manual zoom lens for inspection, machine vision and robotics applications.
Which controls are manual?
Aven lists manual iris, focus and zoom adjustment.
Does 10X mean a fixed 10X image on my monitor?
No. Aven describes 10X manual zoom. Displayed magnification also depends on the imaging setup; the supplied optical table separately lists 0.084X–0.84X optical magnification.
What mounting connection does it use?
Aven lists a C-mount connection. Confirm the full mechanical and optical fit with your camera and mounting equipment.
What focus range is listed?
Aven's features and optical table list 0.15–0.45 m.
Why does the optical table show a different model number?
The supplied product header says 26700-181, while the table says 26100-181. The SKU is retained as listed in the product header; confirm critical optical specifications with the manufacturer before system integration.
Does this listing include a camera or microscope system?
This is a lens listing, not a complete camera, monitor or microscope system.
