Monocular Indirect Ophthalmoscope Wide Angle Twin Mag Ophthalmoscopy just got easier! The Keeler Wide Angle Twin Mag has a 10x larger field of view and is easier to use than a direct ophthalmoscope. The glass optical system provides nonpolarized light giving you two exceptional views and magnifications in a lightweight, easy to use instrument. You will immediately see the difference! Non-polarized light The non-polarized Xenon illumination provides whiter, brighter light that does not compromise your diagnostic information so it minimizes your chance of missing a tumor, any critical vascular changes and early macular degeneration. Lightweight and comfortable to hold It has been designed to fit comfortably into one hand with all easy to operate controls conveniently located at your fingertips. Small pupil capabilities The Wide Angle Twin Mag provides you with the ability to view easily and quickly through undilated pupils. No field loss with spectacles The unique extendable eyepiece allows you to view the retina with or without glasses with the same field of view. Glaucoma diagnosis and monitoring The Wide Angle Twin Mag provides easy assessment of cup to disc ratio as an aid to glaucoma diagnosis and monitoring. Corneal examination Combined with the cobalt blue filter, this unique lens (optional) allows examination of corneal pathology and contact lens fitting. Compatible with Keeler NiCad or Lithium handles and chargers The Wide Angle can be connected to your existing NiCad or Lithium handle. Filters The red free and cobalt blue filters can be used with the large apertures. Multiple aperture selections The large range of built-in apertures provides easy changes from Macular (small pupil), Intermediate, Large, Slit, Glaucoma and Semi-Circle.   Twin Mag delivers 2 reflex and shadow free images of the retina     Mag 1 The large 250 field of view is ideal for general examination and provides 15X retinal magnification and a 10X larger view of the retina than with a standard ophthalmoscope.
