Applications

Where LMHS-MH1825-10MP is specified

A C-mount FA lens for 1.1″ 10MP cameras that need a larger image circle than 2/3″. Typical stations below.

AOI / automated optical inspection

Distortion -0.49% @ y=8 mm keeps pass/fail geometry usable at the field edge, so the AOI threshold is not eaten by the lens before the part varies.

Robotic guidance and pick-and-place

Fixed 25 mm prescription and C-mount BFL 12.6 mm hold calibration between changeovers. Swap a catalog unit without re-tuning the cell.

Inline quality monitoring

1.1" volume stations for presence, polarity, and cosmetic checks. F1.8–close covers the working aperture on this barrel.

1.1" C-mount machine vision cameras

Matched to this sensor class. Send the camera or Sony IMX part number and we confirm image circle and CRA against LMHS-MH1825-10MP.

Inquiry

How to specify this lens

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

01

Camera or sensor PN

Sony IMX or the camera model. We confirm 1.1" format, image circle, CRA, and C vs CS mount against LMHS-MH1825-10MP.

02

Working distance and object size

Distance from the lens and the field you need to cover. If 25 mm is wide or tight, we shortlist 16 mm or 35 mm from the same series.

03

Sample qty and annual volume

Catalog FA sampling from 50 pcs standard MOQ. Annual quantity sets production slot and price break.

04

What you need back

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

Factory

Built and tested in our own optics factory

Every Lensmind FA 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
  • 1 μm-class active alignment before the barrel is locked
  • Per-batch MTF, distortion, and BFL records with the shipment

FAQ

Questions buyers ask about LMHS-MH1825-10MP

What is the LMHS-MH1825-10MP FA lens?
LMHS-MH1825-10MP is a 25 mm F1.8–close C-mount factory-automation lens for 1.1" machine vision cameras. It is a catalog part in the Lensmind HS FA series, used on AOI, robotic guidance, and inline inspection stations.
What cameras and sensors does it fit?
It is specified for 1.1" sensors on C-mount. Back focal length is 12.6 mm. Send the camera or sensor part number — Sony IMX and similar — and we confirm image circle, CRA, and mount against this model or a nearby focal length.
What does distortion -0.49% @ y=8 mm mean on the line?
Geometric error at the field edge shows up as false rejects or offset picks. LMHS-MH1825-10MP is held at -0.49% @ y=8 mm so the image stays usable into the corners of a 1.1" sensor, without relying on software warp as a crutch.
What FOV and focusing range should I plan for?
On a 1.1" sensor the field of view is 36.21° / 29.08° / 21.86° (D / H / V). Focusing range is 0.15 m ~ ∞. Filter thread is M30.5×P0.5 if you need a bandpass or polarizer in front of the lens.
Can you customize focal length, F/#, or mount?
Yes. 25 mm F1.8–close C-mount is the catalog starting point. Custom focal length, aperture, and mount variants are quoted from your sensor drawing. Feasibility typically comes back with the first reply, within one business day.
Do you send a datasheet, MTF, and mechanical drawing?
Yes. Open the inquiry form with the model, sensor, and quantity. The reply includes the datasheet plus the distortion and MTF records for this part. Mechanical drawings go out at quotation stage.
What is the sampling MOQ?
Catalog FA 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. Repeat catalog orders follow the same ISO 9001 release path as the first batch.
Should I use 16 mm, 25 mm, or 35 mm?
LMHS-MH2016-10MP is 16 mm, FOV 53.94° / 43.92° / 33.45°, focus 0.1 m ~ ∞. LMHS-MH1825-10MP (this page) is 25 mm, FOV 36.21° / 29.08° / 21.86°, focus 0.15 m ~ ∞. LMHS-MH2035-10MP is 35 mm, FOV 26.10° / 20.83° / 15.72°, focus 0.2 m ~ ∞. Match FOV to working distance and object size, or send both and we shortlist.
