Where LMQXYK1941A is specified

A compact industrial endoscope / borescope objective specified around insertion-tube OD and FOV. Typical stations below.

Aviation and turbine bore inspection

FOV 78° on a 1/9" sensor for engine bores and fuel passages. TTL 2.2 mm.

Automotive cavity and gearbox checks

Oil- and fuel-wetted service is specified per program. LMQXYK1941A is matched to BF3703 / GC0312.

Pipeline and wind-gearbox RVI

Tube-matched OD and FOV, with in-house IP67/IP68 validation on the module path.

NDT videoscope fleets

Field-replaceable front ends with per-batch image-quality records. Send tube OD and sensor PN against LMQXYK1941A.

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. LMQXYK1941A is matched to BF3703 / GC0312 on a 1/9" format.

Working distance and field

Tube inner diameter, working distance, and the field you need. If 78° is wide or tight, we shortlist 90° or 86° 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.

Questions buyers ask about LMQXYK1941A

What is the LMQXYK1941A endoscope lens?

LMQXYK1941A is a 78° F3.5 industrial endoscope lens for 1/9" sensors. TTL 2.2 mm, resolution 1 MP, matched to BF3703 / GC0312. Catalog part on the Lensmind QXYL sheet.

What cameras and sensors does it fit?

Specified for 1/9" with matched sensor BF3703 / GC0312. TTL is 2.2 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 78° (diagonal). TTL is 2.2 mm. F/# is F3.5.

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 90°, 78°, or 86°?

LMQXYK2086B031 is FOV 90°, TTL 2.9 mm, F2.6. LMQXYK1941A (this page) is FOV 78°, TTL 2.2 mm, F3.5. LMQXYK1503A046-F is FOV 86°, TTL 3 mm, F3.8. Match FOV to tube and working distance, or send both and we shortlist.
