Ophthalmoscopes



img The ophthalmoscope with superior aspherical optics

Features img Halogen HPXTM lamp provides 30% brighter, whiter light output than standard lamps for true tissue color and consistent, long-lasting illumination.
img Coaxial optics produce a shadow-free spot, easier entry into undilated pupils, and a larger field of view.

img Polarizing filter virtually eliminates corneal reflection.
img Red-free filter may be used with any aperture.
img 18 unique aperture/filter combinations for greater versatility: micro, small, and large spot sizes, cobalt blue filter for corneal exams, fixation target, and slit aperture (all on a 6position, continuously rotating aperture dial). Plus: red-free filter, polarizing filter, and unfiltered Halogen HPX on a 3-position switch — each position can be engaged with each of the 6 positions of the aperture dial, for a total of 18 possible combinations. Sealed optics keep out dust and dirt for years of maintenance-free operation.

img Rubber brow rest prevents scratching of eyeglasses.
img 28 focusing lenses with a range of -25 to +40 diopters (Model 11720).
img 68 focusing lenses with a range of -25 to +40 diopters (Model 11730).
