Welch Allyn AutoStep Coaxial 3.5 Volt Ophthalmoscope

Patented coaxial optics, Halogen HPX illumination, and 68 focusing lenses combine for premium quality.

Features:

• Halogen HPX lamp provides 30% brighter, whiter light output for true tissue color and consistent, long-lasting illumination
• Coaxial optics produce a shadow-free spot, easier entry into undilated pupils, and a larger field of view
• 18 aperture/filter combinations for greater versatility: micro, small, and large spot sizes, cobalt blue filter for corneal exams, fixation target, or slit aperture can be combined with red-free filter, polarizing filter, or unfiltered Halogen HPX illumination
• 68 lenses in single-diopter steps for precise resolution (+38 to -30)
• Sealed optics keep out dust and dirt for years of maintenance-free operation
• Rubber brow rest prevents scratching of eyeglasses
