Product Details

The LS-LC0.9 Collimated Light Source is a precision optical illumination system specifically designed for camera optical performance evaluation. Featuring a low divergence angle of 0.9° and illuminance of up to 30,000 lux at 500 mm, the system accurately reproduces the collimated characteristics of sunlight. Utilizing a high-power LED emitter combined with a precision optical collimation system, the LS-LC0.9 generates a stable, uniform, and high-intensity parallel beam, providing a reliable illumination environment for camera testing.

When imaging under strong light conditions, cameras often exhibit optical artifacts such as flare, ghost images, and stray light, which can significantly impact image quality. By simulating the collimation characteristics and angular distribution of sunlight, the LS-LC0.9 enables effective evaluation of lens performance, anti-glare capability, and overall optical system robustness. Engineers can perform both qualitative visual inspections and quantitative image analysis to assess camera performance under challenging illumination conditions.
