Printing and web inspection
Object FOV 700–2800 mm at WD 520–2000 mm is the sheet window for this SKU. Match it to web width so the line uses the full 4K 7 μm sensor.

A 20 mm F4 line scan lens for 4K 7 μm cameras. Typical continuous-scan stations below.
Object FOV 700–2800 mm at WD 520–2000 mm is the sheet window for this SKU. Match it to web width so the line uses the full 4K 7 μm sensor.
Large-format aberration control on a line-scan barrel. Resolution 63 LP/mm is the official JJXS value for LMJJ-LS2040A-0.02X.
Continuous webs need even illumination across the line. Specify this SKU when the working distance falls in 520–2000 mm.
Mount M42. Send the camera body (Basler, JAI, Keyence, Cognex or other) and we confirm flange and image-circle coverage against LMJJ-LS2040A-0.02X.
Send these four items and an engineer replies with datasheet, MTF/distortion records, and pricing within one business day.
Line pixels, pitch, and camera mount. We confirm 4K 7 μm coverage and M42 against LMJJ-LS2040A-0.02X.
Web width and distance from the lens. If 700–2800 mm is wide or tight, we shortlist 0.065× in the same family.
Catalog line-scan sampling is quoted per project. Annual quantity sets production slot and price break.
