High-res imaging of intact cleared tissue

XL2 combines high-resolution volumetric imaging with flexible sample handling and an integrated acquisition-to-analysis workflow.

Detail, consistency and flexibility in one workflow

High-resolution volumetric imaging

Resolve fine structures across intact cleared tissues without physical sectioning.

Uniform imaging across dense samples

More consistent illumination with fewer dark regions and less striping.

Flexible sample handling

Adapt to different specimens, clearing methods, immersion media and imaging scales.

Integrated workflow

Move from acquisition and processing to 3D rendering and downstream analysis.

The optics behind the image

LiT was founded around patented Line Bessel Sheet technology. XL2 combines it with four-side illumination, refractive-index correction and a range of objectives.

Line Bessel Sheet
Long, thin light sheets for high-resolution imaging with reduced side-lobe background
Four-side illumination
More uniform illumination across dense cleared samples with less striping and shadowing
RI correction optics
RI 1.33–1.58
Adjustable refractive-index correction from 1.33 to 1.58 for different clearing media
Multiple objectives
4×5×10×16×25×
Flexible magnification from whole-sample overview to fine structural detail
Proven in practice
