Why Choose BL3 Series
- Edge-to-Edge Uniformity: The BL3 diffused backlight provides perfectly uniform illumination across the entire emission area, enabling repeatable dimensional measurements and high-accuracy defect detection in automated inspection lines.
- Scalable Modular Sizes: Available in emission areas from 100×100 mm up to 500×500 mm in multiple configurable increments, the BL3 adapts to any field of view requirement — from small-component counting to large-format web inspection.
- IP54 Industrial Protection: The robust anodized aluminium frame and IP54-rated enclosure ensure reliable operation in harsh factory environments, including food, pharmaceutical and logistics applications with dust and splash exposure.
- Integrated LED Driver: On-board constant current driver with external ON/OFF control via digital signal enables direct PLC synchronization for high-speed strobe or continuous operation without external controllers.
- 48-Hour Test Certificate: Every BL3 illuminator is subjected to a 48-hour burn-in test cycle. An individual functional test certificate is issued with each unit, guaranteeing photometric consistency from installation day one.
