Metaphase MetaBright MB-DT

Tunnel illumination for glossy surfaces

The Metaphase MetaBright MB-DT tunnel light is an elongated version of the traditional dome light that provides indirect, shadow free and uniform illumination. Dome illuminations have superior properties for the inspection of curved objects while minimising shadows and hot spots.

Great for inspection reflective parts such as glossy, metallic or mirror like surfaces. The diffuse tunnel is available with a wide variety of LED colours such as white, red, green, blue, IR, UV (365 and 395 nm) and RGB with independent colour control.

Reasons to select the Metaphase MetaBright DT

Diffuse tunnel light with non-directional illumination

The MB-DT series is designed to work on specular surfaces, as it produces a shadow free, uniform illumination, minimising glare and shadows.

Special diffuser coating

The coating of the reflector is selected to obtain an optimally diffused output, even for non-visible light like UV or IR. The coating reflects up to 99,9% of the light, so there is nearly no light lost compared to a direct illumination.

Intensity control

Adjustable brightness via 0-10V signal for an easy setting of the intensity when used with the digital intensity controller DDC-3.

Available in a selection of sizes and colours

Available in 3 different standard lengths from 451 to 987 mm. LED options range from white and coloured LEDs to IR and UV, RGB.
