1.0X 1.1 Inch Bi-Telecentric Lens 110mm WD for Machine Vision

Field of View on a 2/3 Inch Camera

The PMS-10110CVP111T is a 1.00X bi-telecentric lens, which means the object-side field of view is the same size as the sensor. On a 2/3 inch CCD (8.4 × 7.1 mm) the field of view is therefore 8.4 × 7.1 mm at 1.00X magnification.

The lens supports sensors up to 1.1 inch with a maximum image circle of approximately Φ18.4 mm, so 2/3 inch and 1 inch formats are fully covered and vignetting is not a concern. The complete FOV list for each sensor format is given in the Sensor Compatibility & Field of View table above.

Applications: Connector, Pin, PCB and Precision Part Inspection

A 1X bi-telecentric lens is the working choice whenever the feature being measured is comparable in size to a camera sensor: connector and pin pitch, PCB dimensional checks, machined part metrology, hole diameter and spacing, and edge or contour measurement. The fixed 110 mm working distance leaves room for lighting and fixtures in automated stations.

Because magnification does not shift when the part sits at different heights within the 0.66–1.60 mm depth of field, the same calibration stays valid across the tray or pallet — which is what keeps repeat measurements comparable in production.

Why Bi-Telecentric Beats Object-Side Telecentric at 1X

At 1X magnification, part height is often comparable to the feature size being measured, so perspective error from a conventional or object-side-only design becomes visible in the measurement. A bi-telecentric (double-telecentric) design keeps chief rays parallel on both the object side and the image side, so magnification stays constant across the depth of field and the image geometry does not lean when the part moves.

This model specifies object-side telecentricity below 0.05–0.1° and image-side distortion below 0.05–0.1%, values that hold across the full field because of the symmetric design. If your parts are highly reflective and need coaxial illumination at 1X, the LTCM1-110C coaxial telecentric lens is the object-side alternative — see the FAQ below for the trade-off.

Frequently Asked Questions

Can this 1X bi-telecentric lens work with a 2/3 inch camera?

Yes. The PMS-10110CVP111T supports sensors up to 1.1 inch with a maximum image circle of approximately 18.4 mm in diameter, so a 2/3 inch sensor (8.4 × 7.1 mm) sits fully inside the circle. Vignetting is not a concern, and the full 1.00X field of view is available to the smaller sensor.

What is the field of view of this 1X telecentric lens on a 2/3 inch camera?

At 1.00X magnification the object-side field of view equals the sensor size. On a 2/3 inch CCD (8.4 × 7.1 mm) the FOV is 8.4 × 7.1 mm; on a 1 inch CCD it is 13.13 × 8.76 mm, and on a 1.1 inch CCD it is 14.19 × 10.3 mm. These values follow the Sensor Compatibility and Field of View table on this page.

Does this 1X bi-telecentric lens have coaxial illumination?

No. The specification table lists coaxial illumination as No for this model. If your parts are reflective and require coaxial lighting at 1X magnification, the coaxial object-side telecentric model LTCM1-110C is the alternative; this lens remains the direct choice when bi-telecentric stability matters more than coaxial lighting.

Is a 1X telecentric lens suitable for dimensional measurement?

Yes. A fixed 1.00X magnification, object-side telecentricity specified below 0.05–0.1° and image-side distortion below 0.05–0.1% keep part geometry stable within the 0.66–1.60 mm depth of field, which is why 1X bi-telecentric lenses are widely used for connector, pin, PCB and precision part dimensional measurement.
