Leic

a M525 OH4

Leica Microsystems always stands for excellence in optics. Outstanding contrast, brilliance, sharpness, resolution, color fidelity, and precision are hallmarks of Leica surgical microscopes. The Leica OH4 stand not only complements Leica’s M525 optics, but also adds to the overall microsurgical experience with superior movement, innovative illumination, and user-friendly features.

Designed and manufactured using superior materials and the highest quality standards, the premium Leica M525 OH4 is built for long service life and outstanding reliability. The Leica M525 OH4 fulfils Leica’s vision of providing the best viewing conditions and the greatest maneuverability to enable successful surgery.

Leica M525 optics Featuring OptiChrome™

The Leica M525 optics feature the latest Leica OptiChrome™ technology. By integrating new glass, coatings, and design parameters, Leica’s high-resolution OptiChrome™ technology delivers the expanded working distance, greater depth of focus, and additional illumination needed for precision microsurgery and forms the basis for the world’s most advanced optical system. Leica M525 optics deliver the following outstanding benefits:

•Longer 32% extended working distance to 470mm

•Deeper 30% increased depth of focus at same magnification

•Brighter 30% more light intensity

•Sharper Higher contrast and crisper, sharper image

•Smarter AutoIris™ – Coupled illuminated field size and field of view

Advanced illumination

The Leica M525 OH4 features two independent

300W xenon illumination systems.

Three Leica Safety Innovations for the Protection of You and Your Patients

Leica continually develops the best solutions to provide the best illumination. The most important aspect of illumination is the color temperature and non-glare lighting. The Leica M525 OH4 proactively offers innovative solutions for the benefit of the surgeon and the safety of the patient.

Constant illumination

Two completely independent illumination systems: The premium Leica M525 OH4 has a newly designed 300W xenon arc-lamp illumination system, which provides increased light output and improved reliability and heat control. The back up 300W xenon arc lamp automatically switches on upon the first lamp’s failure. This gives the surgeon assurance in knowing that his/her surgery will not be disturbed by a lamp failure.

AutoIris™: Safety for the patient

As magnification increases, the illuminated field diameter decreases: The Leica M525 OH4 features a magnification-con- trolled illumination diameter, which provides a field of illumination that is just as wide as the field of view. This prevents potential tissue overheating outside of the surgeon’s field of observation. AutoIris™ allows for manual override, as well.

BrightCare™: Light intensity within safe levels, always

As working distance decreases, light intensity limit decreases: With the Leica M525 OH4, the working distance controlled light intensity ensures that the light intensity does not surpass safety levels, especially when working with short distances.

Compact, yet provides superior reach and ample overhead room

The Leica M525 OH4 provides the highest overhead reach and the longest reach of any surgical microscope on the market today. Because of the superior reach, you have the ultimate flexibility to place the microscope wherever it is most beneficial for the surgery.
