Carl Zeiss SL 120 Slit Lamp w/ Zeiss AT 020 Tonometer – Used

Description

Condition & Warranty

Used. This Carl Zeiss SL 120 Slit Lamp with Zeiss AT 020 Tonometer package has been fully serviced, optical-bench calibrated, and clinically tested. The legendary Carl Zeiss multi-coated optics deliver crystal-clear visual transmission completely free of internal haze, film, or scratch defects. The 5-step magnification drum shifts crisply into place across all power settings, and the omnidirectional joystick operates smoothly across all mechanical axes. The integrated Zeiss AT 020 applanation tonometer mechanism has been verified for smooth counterbalancing and precise calibration responsiveness. The exterior chassis shows minor superficial cosmetic wear expected for a pre-owned diagnostic instrument. Covered by a 90-day warranty on parts and workmanship.

Carl Zeiss SL 120 Slit Lamp — Used Workstation with AT 020 Tonometry

The Carl Zeiss SL 120 represents the absolute pinnacle of traditional mechanical biomicroscopy, renowned globally for its unmatched optical performance, precise spatial depth, and flawless mechanical craftsmanship. Featuring a parallel Galilean microscope design, the SL 120 incorporates a high-grade 5-step rotational magnification drum ($6\times$, $10\times$, $16\times$, $25\times$, and $40\times$). This wide magnification spectrum allows eye care professionals to perform rapid wide-field corneal screenings at lower powers or detailed endothelial and macular structural reviews at high power without losing parfocality or image sharpness.

This pre-owned workstation package includes the authentic Carl Zeiss AT 020 applanation tonometer, engineered according to the gold-standard Goldmann contact principle. Mounting securely onto the slit lamp’s illumination tower guide, the AT 020 provides immediate, highly accurate intraocular pressure (IOP) measurements during routine anterior segment examinations. Combining classic German optical excellence with rugged long-term durability, this used Zeiss SL 120 setup is an elite asset for any eye care practice.

Research published in the National Library of Medicine demonstrates that high-transmission Galilean optical systems with multi-coated glass lenses significantly improve retinal and corneal contrast resolution, enabling early detection of subtle ocular surface pathologies and glaucoma-related structural changes during Goldmann-style applanation tonometry.
