Where LMJJ-TL2X110N23(D28) is specified

A 2X non-coaxial C-mount telecentric lens for 2/3" cameras. Working distance 110 mm. Typical stations below.

Dimensional gauging

Object-space telecentricity holds magnification when part height changes. Sheet telecentricity is <0.3°; distortion is <0.07%.

Connector, pin, and lead inspection

2X covers an object field of 4.4×3.3 mm at 110 mm. Use this when pitch and coplanarity must not move with Z.

Thread and fastener metrology

Locked magnification keeps pitch and profile comparable from station to station. Non-coaxial illumination is the catalog starting point for this barrel.

2/3" C-mount machine vision cameras

Matched to this sensor class. Send the camera or Sony IMX part number and we confirm image circle against LMJJ-TL2X110N23(D28).

How to specify this lens

Send these four items and an engineer replies with datasheet, telecentricity/distortion records, and pricing within one business day.

Camera or sensor PN

Sony IMX or the camera model. We confirm 2/3" format and C-mount against LMJJ-TL2X110N23(D28).

Object size and working distance

Object size and the distance from the lens. If 2X is wide or tight, we shortlist 1.5X or 4X in the same type and sensor class.

Illumination

This model is non-coaxial. Say if you need a coaxial port or a non-coaxial barrel so the first shortlist is the right type.

Sample qty and documents

Catalog sampling from 50 pcs standard MOQ. Name datasheet, 3D, or telecentricity/distortion records in the message.

Built and tested in our own optics factory

Every Lensmind telecentric lens is machined, coated, cemented, and aligned in-house in Hangzhou. Core optical steps are not outsourced, so a drift found at final test can be traced the same day.

ISO 9001 process control on the production line

Questions buyers ask about LMJJ-TL2X110N23(D28)

What is the LMJJ-TL2X110N23(D28) telecentric lens?

LMJJ-TL2X110N23(D28) is a 2X non-coaxial C-mount telecentric lens for 2/3" machine vision cameras. Working distance is 110 mm. It is a catalog part in the Lensmind LMJJ telecentric line.

What cameras and sensors does it fit?

It is specified for 2/3" sensors on C-mount. Object field is 4.4×3.3 mm. Send the camera or sensor part number and we confirm image circle against this model or a nearby magnification.

What do distortion <0.07% and telecentricity <0.3° mean on the line?

Distortion <0.07% is the official sheet value at this magnification — geometric error at the field edge. Telecentricity <0.3° is the residual chief-ray angle, which is what remains of perspective error after the telecentric stop. Both are measured, not estimated.

Is this coaxial or non-coaxial?

LMJJ-TL2X110N23(D28) is listed as non-coaxial on the Lensmind telecentric sheet. Coaxial barrels take on-axis illumination through a side port; non-coaxial barrels are used with external lighting.

Can you customize magnification, WD, or mount?

Yes. 2X at 110 mm C-mount is the catalog starting point. Custom magnification, working distance, and mount variants are quoted from your sensor and gauging drawing.

Do you send a datasheet and telecentricity/distortion records?

Yes. Open the inquiry form with the model, sensor, and quantity. The reply includes the datasheet plus telecentricity and distortion records for this part. Mechanical drawings go out at quotation stage.

What is the sampling MOQ?

Catalog telecentric lenses support sampling from a 50 pcs standard MOQ. Custom programs start from a drawing or a physical sample, then run prototype-to-mass-production.

Should I use 1.5X, 2X, or 4X?

LMJJ-TL2X110N23(D28) (this page) is 2X, WD 110 mm, object FOV 4.4×3.3 mm, distortion <0.07%. LMJJ-TL4X65N23 is 4X, WD 65 mm, object FOV 2.2×1.55 mm, distortion <0.05%. Match field to working distance, or send both and we shortlist.
