Slit Lamp SL-1911
This is a Haag Streit type slit lamp with 5-step magnifications. It adopts the Galilean parallel angle microscope design, which makes it easy to add a beamsplitter and camera interface to upgrade to a digital slit lamp.
Optimal Optical Design
The 1911 slit lamp’s high-quality optics easily enable stereoscopic observation, presenting a realistic visual effect. Corneal endothelial cells can also be observed in great detail under this slit lamp.
Optional Yellow Filter
An external yellow filter can be used in conjunction with a blue filter for fluorescein staining examination to filter out stray light, improve contrast, and effectively observe detailed lesions in the anterior segment.
Integrated Beam Splitter
The integrated beam splitter simplifies installation; its 5:5 beam splitting design evenly distributes light into two paths, simultaneously meeting the needs of digital acquisition and real-time observation.
IOP Measurement and Retina Examination
A specially designed mounting bracket for applanation tonometers on slit lamps is also available. If you wish to purchase the 1911 slit lamp and an applanation tonometer together, we will offer you a good price.
An optional omnidirectional lens holder for the 1911 slit lamp is available for use with an aspherical lens, enabling convenient fundus examination in any direction.
The classic 5-step drum-type design on the 1911 slit lamp improves confocal stability during magnification switching.
The 14mm large spot size design provides a wider field of view and observation range.
With its clear scale and precise control, every detail showcases the exceptional quality of the 1911 slit lamp.
