Basler Standard Light Ring-70OD-x

Standard Light Ring-70OD-x

The Basler Standard Light Ring-70OD-x is a ring-shaped bright-field light mounted around the camera lens to minimize object shadows, with an illuminated ring surface of roughly 53-72 mm. It is offered in four single-color SKUs - White (5000 K), Red (625 nm), Blue (465 nm) and IR (850 nm) - each driven by 24 VDC (+/-10%, 6 W) through a 4-pin M8 connector. An integrated internal LED controller offers two operating modes (voltage and current control) for continuous operation, while strobe/overdrive operation is supported in combination with the Basler SLP Strobe Controller. The black anodized aluminum housing with PMMA cover measures 80 x 92 x 12 mm, weighs 120 g, carries IP54/IP67 ratings and is recommended for working distances of 75-200 mm.

Technical overview

The Basler Standard Light Ring-70OD-x is a bright-field ring light that mounts coaxially around the camera lens, with a 70 mm outer diameter and a light-emitting ring surface of roughly 53-72 mm. Because the LEDs encircle the optical axis, illumination arrives nearly parallel to the camera's line of sight: this floods the part with even, frontal light and suppresses the cast shadows that an oblique single-sided lamp would throw across the field. That makes it a general-purpose front-light for reading surfaces that face the camera squarely - flat labels, printed marks, populated boards, packaging faces - where you want a bright, broadly uniform image rather than the grazing-angle emphasis a dark-field setup produces. Basler recommends a working distance of 75-200 mm, so it is built for close-range inspection rather than long stand-off scenes, and the PMMA light cover acts as a diffusor to soften the individual LED hotspots.

Wavelength is the lever this family gives you, and it ships as four single-color SKUs: White at 5000 K, Red at 625 nm, Blue at 465 nm, and IR at 850 nm. White is the safe default for color imaging and human-recognizable scenes; Red 625 nm is the workhorse for monochrome contrast and pairs cleanly with a matched red bandpass filter to reject ambient light; Blue 465 nm raises contrast on certain dyes, inks, and fine surface texture; and IR 850 nm pushes illumination outside the visible band, which is useful for seeing through some materials, ignoring visible-color variation, or running covertly without a visible flash. Note these are distinct order numbers - you pick the color at purchase, not by switching modes - so the wavelength decision has to be made against your part and your camera's sensor before you buy.

Electrically the ring is simple to design in. It runs on 24 VDC at 6 W through a 4-pin M8 connector, and it carries an integrated internal LED controller offering two operating modes - voltage control and current control - for continuous operation, so no external driver box is required for steady-state lighting. For strobe and overdrive operation - pulsing the LEDs above their continuous rating in sync with the camera trigger to freeze fast-moving parts or boost short-exposure brightness - you add the separate Basler SLP Strobe Controller. The housing is black anodized aluminum with a PMMA cover, measuring 80 x 92 x 12 mm and weighing 120 g, which is light and shallow enough to clip in front of a compact lens. The standard model is rated IP54 (dust-protected and splash-resistant); IP67 (full immersion-grade sealing) is available only as separate model variants with different order numbers. Operating temperature is specified at 10-30 C, extending to 45 C with adequate heat dissipation, so this is an indoor-cell light, not an oven-side or outdoor fixture.

Best for

  • Close-range bright-field front lighting of flat, camera-facing parts (labels, printed packaging, populated PCBs) at 75-200 mm working distance, where even frontal light and minimal shadowing are needed
  • Monochrome contrast and ambient-light rejection using the Red 625 nm variant paired with a matched red bandpass filter, for code reading and OCR/OCV on printed marks
  • Color and general inspection imaging with the White 5000 K variant where natural color rendering of the part matters
  • IR-band imaging with the 850 nm variant to suppress visible-color variation or image without a visible flash
  • Compact, lens-mounted ring illumination in space-constrained cells, given the shallow 12 mm depth and 120 g weight

Selection notes

  • Choose the wavelength SKU up front - White 5000 K, Red 625 nm, Blue 465 nm, or IR 850 nm are separate order numbers, not switchable modes - and match it to your part contrast and the camera sensor's spectral response before purchase
  • Confirm the standoff: this ring is specified for a 75-200 mm working distance, so verify your lens field of view and focus fall inside that band rather than reaching for a long-distance scene
  • Budget the controller path early - continuous operation runs off the integrated internal controller (voltage or current mode) with no extra box, but strobe/overdrive requires the separate Basler SLP Strobe Controller
  • Specify the right sealing variant - the standard model is IP54 only; if washdown or immersion exposure is expected you must order the distinct IP67 model variant (different order number)
  • Plan the power and connectorization for 24 VDC, 6 W via a 4-pin M8, and respect the 10-30 C operating range (up to 45 C with heat dissipation) since this is an indoor-cell fixture
  • As a bright-field ring this excels on camera-facing features but is the wrong tool for grazing-angle defects - dents, scratches and embossing usually need a dark-field or low-angle approach instead
