Holographic Microscopy

Overview

Overview

Our microscopes use a laser (A) and camera (B) to image, count, size and characterize objects in any body of water within the sample area (C).   Resolution extends to objects as small as 0.5 µm and as large as 3 mm.   Our software generates live 3D & 4D holograms (D).
4Deep Microscopy

4Deep Microscopy

Conventional Microscopy

Conventional Microscopy

Narrow focal plane. Staining and prep required. Constrains objects to plane.
Holographic Microscopy

Holographic Microscopy

Everything in field of view is in focus. No staining or prep. Capture movement of objects in 3D.
