Precision Illumination & Detection For Machine Vision Systems

Opto Diode provides high-performance optical components tailored for machine vision and industrial automation applications, where precise illumination and detection are essential for accurate object recognition, inspection, and feedback. At the heart of these systems are paired light sources and detectors—specifically, visible and near-infrared LEDs matched with photodiodes for optimized spectral response and efficiency.

The LEDs offered by Opto Diode emit at key inspection wavelengths (630 nm, 685 nm, 850 nm, and 940 nm) and are engineered for high output power, narrow beam angles, and robust thermal performance. Their stable operation in elevated temperatures and availability in hermetically sealed TO-can packages make them suitable for demanding industrial environments.

To complement these LEDs, Opto Diode’s red- and blue-enhanced photodiodes are spectrally aligned for maximum signal conversion. These detectors are characterized by fast response times, low dark current, and a linear output—ideal traits for high-speed inspection and automated feedback systems.

These components are used in diverse applications, including high-speed part counting, conveyor-based quality assurance, automated label verification, and optical edge and surface feature detection. The rugged design ensures thermal and mechanical stability, while wavelength-matched performance guarantees repeatable and accurate measurements.

Furthermore, Opto Diode offers custom LED and photodiode solutions to accommodate unique wavelength, packaging, or integration requirements. Together, these products enhance the performance and reliability of machine vision systems, supporting precision, speed, and operational endurance in automated industrial settings.
