Leica Microsystems GmbH has released LED illumination modules for stereomicroscopes, which offer optimum illumination even for difficult material samples. The LED3000 NVI offers a vertical illumination light path for challenging illumination applications, including samples with indentations and drill holes not accessible using standard lighting components. The LED5000 CXI (coaxial illumination) provides detailed illumination of flat, highly reflecting surfaces such as wafers or polished metal samples. Bright, homogeneous illumination is offered by the company’s LED5000 RL (ringlight), an all-purpose solution for multiple applications. The LED5000 MCI (multicontrast illumination) delivers high contrast on samples.
