Industrial Applications

1. Robotic End-Effector Vision System for Microelectronics Assembly

Mounted directly on high-speed robotic pick-and-place arms, this TECHSPEC C series lens enables precise alignment of microscopic surface-mount devices (SMDs). The extremely close 0.03 m Minimal Object Distance (M.O.D.) allows the camera to operate in a highly confined space immediately above the components, while the 4.5 mm focal length provides enough spatial coverage to locate scattered parts without raising the robotic arm.

Problem Solved

Prevents focus failure and insufficient field-of-view when cameras must be mounted mere centimeters from the target on space-constrained robotic end-effectors. It utilizes the 8.40 MP resolution and 2.80 µm minimal pixel pitch to guarantee high-precision optical recognition of sub-millimeter PCB traces.

2. In-Situ Automated Optical Inspection (AOI) in CNC Enclosures

The AE00214 lens is deployed in ruggedized compact cameras fixed inside CNC machine tools to verify part dimensions and surface finish directly after milling. Its wide 84.7° horizontal angle of view and 1/1.8" maximal image circle maximize the inspection area in extremely tight enclosures.

Problem Solved

Solves the issue of inspecting bulky machined parts within strictly limited working distances. The f/2 to 11 aperture range adapts to challenging low-light environments inside closed machines, while the 6.8 mm maximal immersion depth ensures seamless mechanical integration with compact protective camera housings that shield against coolant.

3. Roll-to-Roll Web Inspection for Thin-Film Battery Electrodes

Positioned over high-speed continuous web rollers, the lens captures wide-swath images of lithium-ion battery foil coatings or printing materials to instantly detect microscopic pinholes, scratches, and uneven coating distribution.

Problem Solved

Monitoring wide manufacturing webs at high precision typically requires numerous parallel line-scan cameras. By leveraging the ultra-wide 84.7° angle of view paired with the fine 2.80 µm minimal pixel pitch and sharp 8.40 MP resolution, engineers can widen the field of view per camera, drastically reducing camera count while still resolving microscopic coating anomalies.
