Basler Standard Light Back-200x300-x

Standard Light Back-200x300-x

The Basler Standard Light Back-200x300-x is a diffuse backlight with a 200 x 300 mm illuminated surface, built in a black anodized aluminum housing with a PMMA light cover and rated IP54. It is offered in four color SKUs: White (5000 K), Red (625 nm), Blue (465 nm) and IR (850 nm). The light runs on 24 VDC +/-10% with 28 W power consumption (1500 mA for White/Red/Blue, 1800 mA for IR) and includes an internal LED controller supporting continuous and strobe modes, with optional use of the Basler SLP strobe controller. It connects via an M8 4-pin male connector and is recommended for use at a working distance of 1-100 mm.

Technical overview

The Basler Standard Light Back-200x300-x is a diffuse LED backlight, not a front light, and that single fact dictates how it is used: it sits behind the part and floods a 200 x 300 mm field with even, scattered illumination so the camera sees the object as a high-contrast black silhouette against a bright ground. The PMMA light cover is a true diffuser rather than a clear window, which is what produces the homogeneous emission this backlight is built for. With a recommended working distance of just 1-100 mm, the part is meant to ride close to the panel, where edge sharpness is highest and stray light is minimal, making this fixture purpose-built for outline, edge and gap measurement rather than for revealing surface texture or printed marks.

Wavelength choice is the most consequential selection decision here, because the same fixture is offered in four spectral SKUs: White at 5000 K, Red at 625 nm, Blue at 465 nm, and IR at 850 nm. Monochrome cameras gain contrast and depth-of-field benefit from a narrow band, so Red or Blue paired with a matched bandpass filter sharpens the silhouette edge and rejects ambient light, while Blue's shorter 465 nm wavelength can resolve finer edge detail on small features. The IR 850 nm variant pushes the emission outside the visible range, which helps reject visible ambient light and suits cameras with strong near-IR response, and White at 5000 K keeps the option open for color cameras or mixed inspection. All four share the same diffuse geometry, so the engineering trade is purely spectral, and the choice should be locked to the camera sensor type and any filtering already in the optical path.

Electrically and mechanically the unit is straightforward to design in. It runs on 24 VDC (+/-10% per the datasheet, with shop pages citing +/-5%) drawing 28 W, which is 1500 mA for the White, Red and Blue variants and 1800 mA for IR, and it terminates in an M8 4-pin male connector. An internal LED controller provides two operating modes, continuous and strobe, so the light can be driven as a steady source or pulsed in sync with the camera; for strobed operation the optional Basler SLP strobe controller is supported. The black anodized aluminum housing is rated IP54, measures 220 x 350 x 12 mm (H x W x D) and weighs 1600 g, and the thin 12 mm profile makes it easy to recess into a conveyor or fixture plate. Note the modest thermal envelope: a 10-30 C standard operating range, extendable to 45 C only with added heat dissipation, which matters for enclosed or warm cells.

Best for

  • Dimensional measurement of part outlines, gaps and edges where a high-contrast silhouette is needed
  • Presence/absence and completeness checks on packaged goods passing close over the panel
  • Gauging and edge detection on stamped, molded or machined parts riding within 1-100 mm of the surface
  • Silhouette inspection of small electronics and connector pins using the Red or Blue narrow-band variant with a monochrome camera
  • Backlit contrast measurement using the 850 nm IR variant where ambient-light rejection or near-IR camera response is preferred

Selection notes

  • Confirm the part fits within the 200 x 300 mm illuminated area with margin; the silhouette degrades near the panel edge, so keep the feature of interest well inside the field.
  • Match the wavelength SKU to the camera and filtering: White (5000 K) for color or general use, Red (625 nm) or Blue (465 nm) with a bandpass filter on a monochrome camera for the crispest edge, and IR (850 nm) where ambient-light rejection or near-IR sensor response is the goal.
  • Respect the 1-100 mm recommended working distance; backlights lose edge contrast and gain glare as the gap grows, so this fixture is for parts that pass close to the cover.
  • Plan the drive scheme: the internal controller supports continuous and strobe modes on 24 VDC, but strobed operation is supported via the optional Basler SLP strobe controller, and IR draws 1800 mA versus 1500 mA for the visible variants.
  • Account for thermals and ingress: the IP54 rating suits light splash and dust but not washdown, and the 10-30 C standard range (45 C only with heat dissipation measures) should be checked against the cell ambient before installing in an enclosed station.
