The FD1 series flat dome LED illuminators from Visiotronix Photolux (RODER VISION) are high intensity diffused dome illuminators with a central aperture for coaxial camera mounting: the diffused light creates uniform “dome” lighting that eliminates shadows and reflections, ideal for curved, glossy or reflective surfaces.
- Diffused dome lighting, uniform, without shadows or reflections
- Central aperture for coaxial mounting of the camera
- 10 sizes from 150×150 to 550×650 mm
- 4 colors: 5000K white, 470 nm blue, 625 nm red, 850 nm infrared
- High luminous intensity, up to 12,000 cd in white
- 24 Vdc ±5% power supply, MCCD + RCCR© driver for metrological repeatability
- Clear protective glass, HTTM©, aluminium frame with T-slots, M8 connector, IP40
The FD1 series is an advanced family of flat dome LED illuminators. Derived from the DC6 ring series, it combines a modular matrix of 50×50 mm tiles with diffusing optics that turn high intensity light into uniform “dome” lighting: this effect eliminates shadows and reflections and is particularly effective on curved, glossy or reflective surfaces. The central aperture makes it possible to mount the camera lens along the optical axis, capturing images free of shadows.
To guarantee metrological grade repeatability, the internal MCCD and RCCR© drivers stabilise the current across all the LEDs; HTTM© technology preserves their thermal integrity. The M8 connector with anti-vibration ring nut, the reverse polarity protection, the clear protective glass and the aluminium frame with T-slots ensure industrial reliability.
