FAQ of 2/3 Inch Machine Vision Lens

1. Does “2/3 inch” in 2/3 Inch Machine Vision Lens refer to the physical diameter of the lens?

No. “2/3 inch” identifies the supported sensor format rather than the lens body diameter. The FT230 12–75 mm models specify an approximately 11 mm maximum sensor size and image circles from 11.4 to 11.8 mm.

2. Can the FT230 2/3 Inch Machine Vision Lens fully cover a 1-inch sensor?

No. The FT230 series is specified for sensors up to 2/3 inch, so complete coverage of a larger 1-inch sensor is not guaranteed. Using the full sensor area may cause dark corners or incomplete image coverage.

3. Can a 10MP-rated 2/3 Inch Machine Vision Lens be used with a 5MP or 8MP camera?

Yes. The 10MP rating indicates the maximum supported optical resolution class, not a minimum camera resolution. The lens can be used with lower-resolution cameras, but it cannot increase the camera’s actual pixel count.

4. Is the 10MP performance of this 2/3 Inch Machine Vision Lens guaranteed across the entire image at every aperture?

No. The page specifies support for 10MP and 2.5 μm pixels but does not provide MTF curves or resolution data for different apertures and image positions. Critical inspections should be tested at the intended aperture, working distance and sensor position.

5. Does the FT230 2/3 Inch Machine Vision Lens require a driver or software installation?

No. It is a passive C-mount optical lens and does not require a driver, firmware or network configuration. Software is required for operating and configuring the connected industrial camera, not the lens itself.

6. Does the page specify environmental ratings for the FT230 2/3 Inch Machine Vision Lens?

No specific IP rating, operating-temperature range, shock limit or vibration rating is listed. Although the product is described as industrial-grade, these environmental limits should be confirmed before use in washdown, high-vibration or extreme-temperature equipment.
