The SL-2G is a clinical slit lamp for use in eye examination. It features a compact illumination unit with an LED instead of traditional bulbs. The unit houses the adjustable slit mechanism with up to 14mm of aperture. The slit angle can be rotated 180 degrees and a set of red free and cobalt blue filters can be inserted by lever movement. Magnification changes are done through a rotating drum with 10X, 16X and 25X magnification. The oculars are Galileo convergence type and accept the attachment of a beam splitter. Optional mounts for R-900 and 870 type applanation tonometers are available.
