LE005 Series Transmissive Light Source ——High-Uniformity, High-CRI Illumination System for Image Quality Testing

The LE005 Series Transmissive Light Source is designed for objective camera image quality evaluation.
When used with dedicated test charts, it enables accurate and repeatable measurement of key imaging parameters, including:

· Dynamic Range (DR)

· Auto Exposure (AE)

· Auto White Balance (AWB)

· Signal-to-Noise Ratio (SNR)

The system provides stable, uniform, and spectrally controlled illumination, supporting consistent image quality testing across laboratory validation and production environments.

Designed for Camera Image Quality Evaluation

The LE005 Series is developed to meet the requirements of camera and imaging system testing, where illumination uniformity and color fidelity directly affect measurement accuracy.

Typical application areas include:

· Camera module development and verification

· Image quality benchmarking

· Algorithm tuning and validation

· Production-line image quality inspection

· Single CCT or multi-CCT adjustable transmissive light sources
· High-brightness, wide dynamic range transmissive illumination
· Ultra-high brightness transmissive light sources
· Dedicated AE exposure testing light sources
· Flicker testing light sources
· Infrared (IR) transmissive light sources

The LE005 Series supports configuration customization, allowing illumination parameters to be tailored to specific testing standards, camera types, and application requirements.

Key Benefits

· Uniform and stable illumination for objective image quality measurement

· High color rendering performance suitable for color-related testing

· Compatible with standard image quality test charts

· Scalable configurations for different testing environments

· Customizable solutions to meet specific application needs
