Topcon SL-D701 LED Slit Lamp

The Topcon SL-D701 is a high-resolution, digital-ready slit lamp featuring
a bright, homogeneous 450,000 Lux LED (or halogen) light source,
five magnification steps (6times) to (40times), and superior imaging capabilities.
It supports the optional DC-4 digital camera for video and image capture
and the BG-5 background illuminator for meibography. [1, 2, 3, 4, 5]

Key Features of the SL-D701:
Illumination System: Available with LED or halogen,
with the LED providing consistent color temperature
and enhanced visualization of minute details in the anterior chamber and vitreous.
Magnification and Optics: Utilizes a Galilean-type head with a 5-step drum rotation
for quick changes: \(6\times, 10\times, 16\times, 25\times, 40\times\).
Digital Imaging (Optional): Compatible with the DC-4 digital camera and
the BG-5 LED Background Illuminator for still images, video, and Meibomian gland observation.
Filters: Includes four built-in filters: Cobalt blue, red-free, neutral density,
and an amber filter to improve contrast for retinal observation.
Blue Free Filter™: Enables superior fluorescence observation (up to 1.6x brighter)
in combination with the yellow filter, which is particularly useful
for detecting dry eye and ocular surface issues.
Design: Features a convergent binocular tube for sharp stereoscopic observation
and a joystick trigger button that provides an illumination boost.
Operating Range: Slit width 0–14 mm, slit length 1–14 mm, and
a Diopter adjustment range of -5D to +5D. [1, 2, 3, 4, 5, 6, 7]
