Sensor board S spacer, 0.25 mm IDS Accessory

Technical Overview

The Sensor board S spacer is a precision technical component designed to isolate and adjust the flange focal distance between the imaging sensor and the lens mount. With a defined thickness of 0.25 mm, this spacer is positioned between the sensor board and the lens holder to facilitate optimal optical alignment, particularly in specialized and customized imaging projects using uEye ACP modular cameras.

Industrial Applications

1. High-Precision Automated Optical Inspection (AOI) for PCB Assembly

Integration into high-resolution machine vision systems where custom lens carriers are employed to fit tight mechanical envelopes. The 0.25 mm spacer allows optical engineers to fine-tune the optics to match the exact focal requirements of the Sensor board S.

Problem Solved

Custom machined lens carriers often introduce slight mechanical deviations that shift the focal plane. The 0.25 mm spacer corrects the flange focal distance, ensuring the edge-to-edge sharpness that is crucial for detecting micro-defects in solder joints and miniature SMD components.

2. Embedded Vision for Compact Medical Diagnostic Equipment

Utilization within compact medical diagnostic devices, such as desktop blood analyzers or in-vitro imaging systems, which require customized optical assemblies to fit proprietary chassis designs while maintaining electrical isolation of the bare sensor board.

Problem Solved

Standard lens mounts are often too bulky for miniaturized medical devices, necessitating custom carriers. The AL00062 spacer provides the critical 0.25 mm offset to precisely adjust the back focal length and safely isolate the custom metallic lens carrier from the Sensor board S circuitry.

3. Stereo Vision Calibration for Robotic Bin Picking

Deployment in robotic 3D stereo vision arms where two embedded Sensor board S units are mounted on a single customized stereoscopic lens carrier. The spacers are used to mechanical align and calibrate the focal planes of both imaging sensors perfectly.

Problem Solved

Mechanical tolerances in dual-lens custom carriers can cause a focal mismatch between the left and right cameras, severely degrading 3D depth map accuracy. Inserting the 0.25 mm spacer ensures the flange focal distances are identical across both sensors, enabling highly precise depth perception for robotic grasping.
