Where LMJJ-LS8040A-0.75X is specified

A 80 mm F4 line scan lens for 12K 5 μm cameras. Typical continuous-scan stations below.

Printing and web inspection

Object FOV 63–91 mm at WD 147–185 mm is the sheet window for this SKU. Match it to web width so the line uses the full 12K 5 μm sensor.

Flat panel and display (FPD)

Large-format aberration control on a line-scan barrel. Resolution 100 LP/mm is the official JJXS value for LMJJ-LS8040A-0.75X.

Battery electrode and coated film

Continuous webs need even illumination across the line. Specify this SKU when the working distance falls in 147–185 mm.

12K 5 μm line scan cameras

Mount M42 / M58 / M72-F. Send the camera body (Basler, JAI, Keyence, Cognex or other) and we confirm flange and image-circle coverage against LMJJ-LS8040A-0.75X.

How to specify this lens

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

Camera or sensor PN

Line pixels, pitch, and camera mount. We confirm 12K 5 μm coverage and M42 / M58 / M72-F against LMJJ-LS8040A-0.75X.

Working distance and web width

Web width and distance from the lens. If 63–91 mm is wide or tight, we shortlist 0.5× or 1.0× in the same family.

Sample qty and annual volume

Catalog line-scan sampling is quoted per project. Annual quantity sets production slot and price break.

What you need back

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

Built and tested in our own optics factory

Every Lensmind line scan 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

Questions buyers ask about LMJJ-LS8040A-0.75X

What is the LMJJ-LS8040A-0.75X line scan lens?

LMJJ-LS8040A-0.75X is a 80 mm F4 line scan lens for 12K 5 μm cameras. Object FOV 63–91 mm, working distance 147–185 mm, mount M42 / M58 / M72-F. Magnification 0.75×. It is a catalog part on the Lensmind JJXS sheet.

What cameras and sensors does it fit?

It is specified for 12K 5 μm is compatible with 8K 7 μm. on mount M42 / M58 / M72-F. Send the camera body and sensor line (pixels × pitch) and we confirm image circle and flange against this model.

What object FOV and working distance should I plan for?

Sheet object FOV is 63–91 mm. Working distance is 147–185 mm. Those are ranges across the focus stroke on the official datasheet — not a single locked magnification unless the PN states one.

What does resolution 100 LP/mm mean on the line?

LMJJ-LS8040A-0.75X is held at 100 LP/mm on the JJXS sheet. That is the official spatial-frequency figure for this SKU. Confirm it against your pixel pitch and Nyquist before locking the optic.

Can you customize mount, F/#, or working distance?

Yes. 80 mm F4 with M42 / M58 / M72-F is the catalog starting point. Custom mount, flange, and WD variants are quoted from your camera 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 line-scan lenses are quoted per project for sampling. 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 0.5×, 0.75×, or 1.0×?

LMJJ-LS8040A-0.5X is 0.5×, object FOV 91–152 mm, WD 188–273 mm. LMJJ-LS8040A-0.75X (this page) is 0.75×, object FOV 63–91 mm, WD 147–185 mm. LMJJ-LS8040A-1.0X is 1.0×, object FOV 47–62 mm, WD 125–147 mm. Match FOV to web width and working distance, or send both and we shortlist.
