Topcon SL-3E Slit Lamp INCLUDES 1-HS R-900 Tonometer Redesigned Optical System Provides Exceptional Image Clarity Topcon has completely redesigned the stereoscopic converging biomicroscope used in the SL-3E, employing innovative new optics that assure unequaled image sharpness. Brighter, More Even Illumination The SL-3E employs brilliant halogen illumination to provide strong, stable lighting for improved observations. The 6V, 20W halogen lamp approximates natural illumination for optimum fidelity of the observed image. Slit image can be inclined about the horizontal axis up to 20 degrees from the axis of observation. Standard magnifications are 10X and 16X with 10X eyepieces, and 16X or 25X with 16X eyepieces. Magnification is conveniently changed by rotating a lever under the oculars. 3 built-in filters and converging optics.
