Optical Clarity You Can Trust for Diagnostic Work

The advanced Infinity Plan achromat optical system, paired with a super-bright 5-watt LED illuminator, produces crisp, flat, high-contrast images from edge to edge. With a generous 20 mm field of view, the EXC-250 supports confident tissue evaluation in brightfield, phase contrast, and 100x oil immersion—ideal for identifying cellular detail, margins, and subtle pathology with consistency and accuracy.

Designed for the Pace of a Clinical Lab

Built on a rugged cast-alloy frame with a compact footprint, the EXC-250 is well suited for busy Mohs labs and pathology suites where reliability matters. Practical features such as an integrated carry handle, cord management, and a built-in USB power port add convenience without cluttering the workspace.

Ergonomics for Long Hours at the Microscope

Extended slide review demands comfort. The EXC-250 features a 30° inclined trinocular head, low-positioned coaxial focus controls, and smooth, low-profile stage controls—all designed to reduce fatigue during long reading sessions and repetitive casework.

---

Ready for Digital Documentation & Collaboration

The standard trinocular head with a 50:50 light split supports Excelis™ cameras as well as USB, HD, or Wi-Fi imaging solutions. This makes the EXC-250 an excellent platform for case documentation, teaching residents, telepathology, and collaborative review.
