DCM Sistemes DOMB2B1A Dome Light

DOMB2B1A

The DOMB2B1A is a "cloudy day" dome light that illuminates objects from the camera axis in all directions, producing a large amount of uniform diffuse light that eliminates highlights and shadows on shiny and curved surfaces. It is the biggest dome in the DOM series, measuring 1309 x 1309 x 613 mm with a 1100 mm bottom aperture and weighing 17.5 kg, with a recommended working distance below 50 mm. It operates from 24 VDC in continuous mode (no controller needed) or in strobe mode using a VST-series strobe controller, drawing up to 190 W continuous (108 W for the 850 nm IR version) or 570 W in strobe. It is available in 470 nm blue, 525 nm green, 630 nm red, 850 nm IR and white (W00), with an IP65-rated, anodized-aluminium housing.

Technical overview

The DCM Sistemes DOMB2B1A is the largest member of the DOM "cloudy day" dome family, built around an exceptionally large 1100 mm bottom aperture in a 1309 x 1309 x 613 mm anodized-aluminium housing weighing 17.5 kg. Like all dome geometries, it floods the scene with light that arrives from every direction along and around the camera axis, so the surface under test effectively sits inside a uniformly bright hemisphere. The result is highly diffuse, near-shadowless illumination that suppresses specular highlights and hot spots on shiny, curved, textured, or irregular parts, the conditions that defeat directional bar, ring, and spot lights. At this aperture the dome is intended to wrap large objects, which is why DCM specifies a very short recommended working distance of under 50 mm between the aperture and the part.

Electrically the unit runs from a regulated 24 VDC ±3% supply over a simple 2-pole pre-cabled flying-lead connection (180 mm leads; brown = +24 V, blue = 0 V). It supports two operating modes from the same fixture: continuous (Type C), which needs no controller and draws up to 190 W (108 W for the 850 nm IR variant), and strobe (Type S), which is overdriven through a DCM VST-series strobe controller and can pull up to 570 W during the pulse. Strobe mode trades duty cycle for instantaneous intensity, which is the practical way to freeze motion or push enough light through a large diffusing dome at short exposures.

The DOMB2B1A is offered in 470 nm blue, 525 nm green, 630 nm red, 850 nm IR, and broadband white (W00), letting you match the wavelength to the contrast mechanism of the application: monochrome wavelength selection for feature enhancement, IR to de-emphasize printed graphics and dyes, or white for color imaging. The anodized-aluminium housing is rated IP40 as standard, with an IP65 option via the /65 modifier for washdown or particulate-heavy environments, and operates over 0-40 °C (storage 0-60 °C). Its size, weight, and sub-50 mm working distance make it a fixed-station, large-part illuminator rather than a compact in-line component.

Best for

  • Large shiny, curved, or reflective parts (stamped metal panels, cans, molded plastics) where directional lighting produces glare and the goal is shadow-free, highlight-free diffuse illumination
  • Surface and cosmetic defect inspection on big objects that must be lit uniformly across a wide area without specular hot spots, including AI-based defect detection that needs consistent, even appearance
  • Dimensional and presence/measurement checks on large items where uniform diffuse light gives clean, repeatable edge and feature contrast regardless of surface curvature
  • Fixed inspection stations with room above the part to mount a 17.5 kg, 1309 mm fixture at a working distance under 50 mm
  • Applications that benefit from wavelength-selective contrast (470/525/630 nm or 850 nm IR) or from strobed overdrive to freeze motion on a moving large part

Selection notes

  • Working distance is very short by design: DCM recommends under 50 mm between the 1100 mm aperture and the part, so confirm your fixturing can place the camera and dome that close to a large object and that the part fits inside the aperture footprint.
  • This is a large, heavy fixture (1309 x 1309 x 613 mm, 17.5 kg). Plan mechanical mounting, access for part loading, and the 24 VDC supply current to cover up to 190 W continuous (or 570 W peak in strobe) before committing.
  • Decide continuous vs strobe up front. Continuous (Type C) needs no controller and is simplest; strobe (Type S) requires a DCM VST-series strobe controller plus camera trigger synchronization, but delivers far higher peak intensity to freeze motion or shorten exposure.
  • Choose the wavelength to suit the task: monochrome 470/525/630 nm for wavelength-based contrast enhancement, 850 nm IR to suppress color and print variation (note the IR version draws only 108 W continuous), or white (W00) for true-color inspection.
  • Match the ingress protection to the environment: the standard anodized-aluminium housing is IP40, while the /65 option provides IP65 for washdown, dust, or food/beverage and packaging lines. Keep within the 0-40 °C operating range (storage 0-60 °C).
