High-luminance backlight for contour, edge and transparent-object inspection
LXV-3FT combines imported ultra-thin SMD LEDs with a compact precision-moulded housing to provide a bright, uniform transmitted-light field. Thirty-three standard models cover emitting areas from 50 × 50 mm to 1763 × 183 mm, while square and rectangular custom fields from 30 × 30 mm to 500 × 500 mm are also available.

Contour dimension measurement
Create a bright background and a dark, sharply defined part silhouette for dimensional measurement.
Damaged-edge inspection
Reveal chips, missing material and irregular outer boundaries against the uniform field.
Transparent impurity inspection
Transmit light through transparent products so inclusions and foreign matter become visible.
Liquid-level inspection
Use the illuminated boundary to locate the fill line in oral-liquid containers.
Optical response, 133 × 100 mm field evidence and contour-inspection result
The LXV-3FT100100-W reference shows how relative luminance changes from 0 to 200 mm working distance and records both dark-field and bright-field images at the same 133 × 100 mm field of view. The metal-logo example keeps the illumination arrangement, workpiece and result separate so the inspection sequence is immediately clear.
Product family and available panel geometry
Compact high-precision housings reduce batch variation. Standard and custom panels can use square or rectangular fields; available output colours include infrared, red, white, blue and green.
LXV-3FT100100-W working-distance and field evidence
Relative luminance is normalised to 100% at WD 0 mm and declines across the 0–200 mm reference curve. Both field images use a 133 × 100 mm field of view and a 10 mm scale.
Metal-logo contour-inspection instance
A camera views the metal logo in silhouette against an LXV-3FT7070-W panel. The result produces a white background and a black contour edge with obvious contrast.

Select one exact field, voltage and colour-specific load
The thirty-three standard rows span 50 × 50 mm through 1763 × 183 mm emitting fields. Red and green/blue/white loads are listed separately; LXV-3FT1210680 is the only standard 48 V row.
- 1
Define the complete silhouette
Include the target, positional tolerance and all features that must remain inside the bright field.
- 2
Choose the smallest suitable field
Match both emitting-area dimensions without mixing values between rows.
- 3
Choose wavelength and load
Validate target contrast, then use the red or GBW wattage from the same exact model.
- 4
Confirm controller and mechanics
Size the supply for the selected voltage and load, then release the matching drawing and mounting pattern.

Use the exact numbered drawing and preserve panel flatness, cable clearance and supply capacity
Every standard model below has its own complete mechanical drawing. Mounting changes with enclosure size, and the three largest formats use through-holes or dense reverse-side M3 patterns rather than the small-panel four-hole arrangement.
- 01
Use only the drawing number assigned to the selected model row.
- 02
Support large panels across the housing so the emitting plane remains flat and aligned with the camera.
- 03
Reserve the complete 500 mm lead, connector bend and any multiple-cable exits shown on the drawing.
- 04
Match the controller to the exact voltage and colour-specific power before release.
