Where LMQX3203B is specified

A compact medical endoscope objective pre-matched to a micro CMOS sensor. Typical programs below.

Disposable endoscope programs

LMQX3203B is a catalog medical objective at FOV 100° and TTL 6.55 mm, pre-matched to OV2740.

Reusable / autoclave-tolerant builds

Hermetic sealing and autoclave cycling are locked in the written specification. The optical starting point is this 1/6" 2 MP module.

Surgical visualization modules

GI, bronchoscope, hysteroscope, and laparoscope programs start from a sub-2 mm objective already matched to the sensor on the board.

OV2740 camera modules

Send the sensor drawing and tube OD. We confirm FOV, TTL, and cover-glass stack against LMQX3203B or a neighbor in the medical group.

How to specify this lens

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

Sensor PN and tube OD

OV / GC / ES part number already on the board. LMQX3203B is matched to OV2740 on a 1/6" format.

Working distance and field

Tube inner diameter, working distance, and the field you need. If 100° is wide or tight, we shortlist 140° or 140° from the same group.

Sample qty and annual volume

Catalog endoscope sampling from a written quantity. Annual quantity sets production slot and price break.

What you need back

Datasheet, MTF, mechanical drawing, or a custom FOV / mount. Name it in the message so the first reply is complete.

Built and tested in our own optics factory

Every Lensmind endoscope lens is ground, coated, cemented, and actively 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 LMQX3203B

What is the LMQX3203B endoscope lens?

LMQX3203B is a 100° F5.5–7.0 medical endoscope lens for 1/6" sensors. TTL 6.55 mm, resolution 2 MP, matched to OV2740. Catalog part on the Lensmind QXYL sheet.

What cameras and sensors does it fit?

Specified for 1/6" with matched sensor OV2740. TTL is 6.55 mm. Send the sensor drawing and tube OD and we confirm FOV and packaging against this model or a neighbor in the same group.

Where is distortion listed?

Distortion is measured per batch and ships with the datasheet pack. The QXYL catalog sheet lists FOV, F/#, TTL, resolution, and matched sensor — those values are on this page. Distortion curves are not a catalog-sheet column.

What FOV and TTL should I plan for?

Catalog FOV is 100° (diagonal). TTL is 6.55 mm. F/# is F5.5–7.0.

Can you customize FOV, F/#, or packaging?

Yes. Catalog FOV and TTL are the starting point. Custom FOV, aperture, cover glass, and tube OD are quoted from your sensor drawing.

Do you send a datasheet, MTF, and mechanical drawing?

Yes. Open the inquiry form with the model, sensor, tube OD, and quantity. The reply includes the datasheet plus MTF and distortion records for this part.

What is the sampling MOQ?

Catalog endoscope lenses support sampling from a written quantity. Custom modules are quoted per specification and annual volume.

Should I use 140°, 100°, or 140°?

LMQX6112A-25A is FOV 140°, TTL 2.9 mm, F4.0–7.0. LMQX3203B (this page) is FOV 100°, TTL 6.55 mm, F5.5–7.0. LMQX3204B is FOV 140°, TTL 3.5 mm, F4.5–7.0. Match FOV to tube and working distance, or send both and we shortlist.
