Kowa SL-19 Hand-Held Portable Slit Lamp

Description

he Kowa SL-19 is a compact hand-held slit lamp designed for professional examination of the anterior segment of the eye, from the corneal epithelium to the posterior capsule.

Weighing approximately 620 g without batteries, it provides a practical solution when the patient cannot be examined comfortably with a traditional tabletop slit lamp. It is especially useful in emergency departments, pediatric care, bedside examinations, mobile clinics and consultations between different examination rooms.

The binocular stereoscopic microscope offers selectable 10× and 16× magnification. Its white LED slit illumination is continuously adjustable from approximately 200 to 20,000 lux and provides three slit widths: 0.1, 0.2 and 0.8 mm. Slit length can be selected at fixed settings of 1, 5 and 12 mm or adjusted continuously from 1.5 to 12 mm.

Independent white background illumination can be used simultaneously with the slit light. The integrated blue LED supports examinations involving fluorescent staining. Both the background and blue illumination systems provide three intensity levels.

The SL-19 operates cordlessly with three AA alkaline or rechargeable Ni-MH batteries. With 1900 mAh Ni-MH batteries, approximate continuous operating time is up to six hours when using the slit light at maximum intensity. Its rounded body, trigger-style control and optimized grip are designed for comfortable handling.
