What is the LUX Infrared Illuminator?

The LUX Infrared Illuminator series provides uniform below-maze infrared backlighting for Ugo Basile's range of IR-transparent maze apparatuses. By illuminating from below at 850 nm, the LUX eliminates shadows and provides consistent animal silhouettes regardless of fur color — making it equally effective for black, white, and agouti coats that challenge conventional overhead IR illumination. The system supports experiments in complete darkness, preventing circadian disruption, light-induced stress responses, and light-aversion artifacts that confound many standard maze protocols.

Key Features

• Below-Maze Illumination: IR light projected from beneath the maze floor creates a uniform silhouette of the animal against the floor, providing superior tracking contrast compared to overhead IR or visible light.
• Adjustable Intensity (0–100%): Stepless dimming from 0 to 100% allows researchers to optimize illumination for specific cameras, mazes, and fur colors without altering the experimental dark environment.
• 850 nm Wavelength: Operates at 850 nm — invisible to rodents, which have poor near-infrared sensitivity — ensuring complete darkness from the animal's perspective throughout the experiment.
• Multiple Sizes: Four models cover maze sizes from 70 × 70 cm (LUX 70) to 160 × 160 cm (LUX 160), matching the footprint of all Ugo Basile IR mazes including Open Fields, Plus/Zero Mazes, Y-Mazes, and Radial Mazes.
• High Load Capacity: Supports maze loads of 35–45 kg (LUX 70/100) and up to 65 kg (LUX 160), accommodating all standard maze apparatus weights.
