BV room - High-Precision Screen Photometry Lab System
The BV Room is a specialized laboratory system designed for automotive lighting, and general lighting research. Built around our core product LMK, the BV Room combines optical precision and automated workflows for both R&D and quality assurance environments.
Engineered for Accuracy, Designed for Flexibility
This modular system scales to your needs — from compact setups under 3 m to expansive 10–25 m measuring distances — and delivers precise luminous intensities, illuminances, and color coordinates for complex light sources. Achieve consistent, standard-compliant results from prototype analysis to production verification.
A complete solution tailored to your application
Assemble your BV room with proven TechnoTeam components:
- LMK 6 or LMK 6 color imaging luminance/metrology devices
- LID Table (for sample positioning)
- Optional further hardware: PC, power supplies
- Software: LabSoft (for R&D workflows), LID-Checker (for both R&D and EOL usage)
