Basler Standard Light Dome-100OD-x

Standard Light Dome-100OD-x

The Basler Standard Light Dome-100OD-x is a machine-vision dome light providing uniform, diffuse bright-field illumination ideal for highly reflective or curved surfaces. It offers a 100 mm luminous area with a 30 mm central lens hole and is offered in four wavelengths: White (5000 K), Red (625 nm), Blue (465 nm), and IR (850 nm). It runs on 24 VDC at 8 W with an internal LED controller supporting continuous and strobe/overdrive operation, and connects via an M8 4-pin connector. The housing is black anodized aluminum with a plastic dome, rated IP54.

Technical overview

The Basler Standard Light Dome-100OD-x is a diffuse dome light built for the single hardest illumination problem in machine vision: imaging glossy, curved, or specular surfaces without hot spots or glare. A dome geometry works by bouncing LED light off the inside of a hemispherical surface so the part is lit from nearly every angle at once. The result is shadowless, near-uniform bright-field illumination that wraps around contours and suppresses the mirror-like reflections you would otherwise get from metal, foil, glossy plastic, or clear film. With a 100 mm luminous-area diameter and a 30 mm central lens hole, the camera looks straight down through the top of the dome while the part sits underneath, fully bathed in diffuse light. The very short recommended working distance of 1-30 mm is the key design constraint: the part must sit close to the dome opening for the wrap-around effect to work, so this is a close-coupled, top-down inspection fixture rather than a standoff light.

The light is offered in four wavelengths from a common housing: White at 5000 K for general color and contrast work, Red at 625 nm, Blue at 465 nm, and IR at 850 nm. Wavelength choice is a contrast tool - longer red and IR wavelengths tend to penetrate and emphasize different surface features and reduce sensitivity to certain printed colors, while shorter blue light can sharpen fine surface texture and edges; the 5000 K white variant is the default when natural color rendition matters, for example in color-dependent OCR/OCV or print verification. Electrically, the unit runs on 24 VDC (+/- 5%) at 8 W and carries an internal LED controller with two operating modes (voltage and current control), so it can be driven directly without an external strobe box for many applications. It supports both continuous and strobe/overdrive operation, meaning it can be pulsed and over-driven in sync with the camera trigger to freeze motion or boost intensity on fast lines - and it remains compatible with the Basler SLP Strobe Controller when precise external strobe timing is wanted.

Mechanically and environmentally the dome is specified for industrial integration but not for harsh washdown. The housing is black anodized aluminum with a plastic dome, the overall footprint is 150 x 150 x 80 mm at 450 g, and connection is via an M8 4-pin male connector for both power and control. Ingress protection is IP54, which means dust-protected and resistant to splashing water - suitable for typical packaging and assembly enclosures but not for high-pressure or submersion environments. The rated operating temperature is 10-30 C, extendable to 45 C with adequate heat dissipation, so the integrator should account for the strobe/overdrive duty cycle and ambient heat when over-driving. For an installer, the practical upshot is a compact, self-driven top-down dome that turns the difficult problem of reading and inspecting shiny, contoured surfaces into clean, even, repeatable images, provided the part can be brought within roughly 30 mm of the dome opening.

Best for

  • Bright-field surface and defect inspection of highly reflective or curved parts - foil-sealed lids, glossy plastics, polished metal, and clear film - where a directional light would create glare or hot spots
  • Reading and verifying printed text via OCR/OCV on shiny or contoured packaging where uniform, shadowless light is needed for reliable character contrast
  • Decoding and grading 1D/2D traceability codes printed or marked on reflective or curved surfaces such as cans, blister packs, and metal components
  • Top-down packaging inspection (seal integrity, print presence, label position) on close-coupled lines where the part can sit within ~30 mm of the dome opening
  • AI-based defect inspection that benefits from consistent, evenly lit training and inference images free of specular reflections

Selection notes

  • Working distance is the gating constraint: the dome needs the part within a recommended 1-30 mm of its opening for the diffuse wrap-around effect, so it suits close, top-down fixturing rather than long-standoff or in-conveyor imaging with large gaps
  • The camera images through the 30 mm central lens hole, so size the lens, sensor, and field of view to fit the 100 mm luminous area and the 30 mm aperture - the dome opening and lens hole effectively cap your usable field for a given working distance
  • Pick the wavelength for contrast, not brightness: 5000 K white for color-faithful work, red 625 nm or IR 850 nm to change how surface features and printed colors render, and blue 465 nm to emphasize fine texture and edges
  • Plan power and triggering around 24 VDC at 8 W with the internal LED controller; the two operating modes (voltage/current) plus continuous-and-strobe/overdrive support let you drive it directly, but for tightly timed external strobe sync consider the compatible Basler SLP Strobe Controller
  • Confirm the environment fits IP54 (dust-protected, splash-resistant) and the 10-30 C operating range (up to 45 C with heat dissipation) - it is not rated for washdown or high heat, and over-driving in strobe mode raises the thermal load to manage
  • Account for the M8 4-pin connector and the 150 x 150 x 80 mm / 450 g footprint when designing the mounting bracket and cable routing for a close-coupled top-down station
