This solution provides two different illumination types in a single, compact, easy-to-integrate system: the dome unit provides non-directional diffused light that can be used to homogeneously illuminate complex shapes with curved and shiny surfaces, effectively eliminating glare and shadows. The low angle ring light unit provides darkfield lightning that can be used to cast shadows, greatly emphasizing surface irregularities, scratches and other details.

LTDMLA illuminators operate exclusively in strobe mode: the reduced heat generation guarantees extended LED lifetime and makes LTDMLA the perfect choice to illuminate very fast moving objects.

The two illumination units can be operated independently and easily powered, controlled and synchronized by compatible LTDV strobe controllers. LTDMLA series is available in:

two sizes: medium and large, respectively with illumination area of 60 mm and 100 mm in diameter;
two power intensities: medium power with driving current up to 7.5 A and high power with driving current up to 17 A.

LTDMLA series features industry standard connection (M12 four poles connector), resizable aperture for the dome unit that can be drilled to increase the diameter and accommodate the optics field of view and effective diffuser for the ring light unit to avoid hot spots formation. Additionally LTDMLA series can be easily mounted and integrated into any machine vision system by means of M6 screws.

KEY ADVANTAGES

Two independent illumination units in one single solution
Dome unit for homogeneous illuminations and low angle unit for dark field lightning can be independently operated.

Ordering information

It’s easy to select the right illuminator for your application: our part numbers are coded as LTDMLAxy-WW where x defines the illuminator size (B = medium, C = large), y refers to the power intensity (1 = medium, 2 = high). For instance LTDMLAB2-WW is a diffusive strobed dome + low angle illumination system - medium size, high power, dome white, ring light white.
