Slit Lamp
The Essilor Instruments SL 450 is a versatile slit lamp designed to give eye care professionals greater flexibility when performing detailed ocular examinations.
Its Galilean binocular optical system combines a wide field of view with five magnification levels ranging from 6× to 40×. Magnification can be changed easily by drum rotation, allowing practitioners to move between broader observation and more detailed examination as required.
Continuous slit adjustment, a tilting illumination tower and a choice of LED or halogen illumination provide additional flexibility. The integrated base and chinrest also make the SL 450 easy to incorporate into a refraction unit or instrument table.
