Q: How does the Coaxial Vision System help when performing a fundus exam?
A: When viewing the fundus it is extremely important that the light beam from the ophthalmoscope and your viewing angle are in close proximity. The path your eye follows through the patient’s eye to the fundus is extremely narrow; therefore, the most efficient method of viewing the fundus is to keep the ophthalmoscope’s light beam and your viewing path in near coincidence.
In all other viewing systems, the viewer looks over the top of the mirror from a steeper angle. The visual axis and axis of illumination do not coincide, so parallax and resultant shadowing are increased.
Q: Should I choose a hard or soft case for my diagnostic set?
A: It's a matter of personal preference. Both cases provide sufficient protection. The hard case lays instruments out very nicely, but the soft case is somewhat smaller. It is very important that your set fit in your lab coat--both Welch Allyn cases allow for this.
Q: How durable is the Welch Allyn otoscope?
A: Extremely durable. Check out the busiest hospital and physician exam rooms to see what otoscope they use when durability counts. Welch Allyn otoscopes are engineered and manufactured for precision and longevity:
· They are manufactured with metal and high-impact ABS material.
· They have reinforced, flush-mounted fiber optics.
· They will maintain their shape, even if dropped.
· A metal, flush mounted insufflator port is included in the design.
Q: How durable is the Welch Allyn ophthalmoscope?
A: Extremely durable. Welch Allyn ophthalmoscopes are engineered and manufactured for precision and longevity.
· The optical tube is constructed of chrome-plated brass for precise alignment and long life.
· The glass condensing lens, objective lens, aperture dial assembly, and red-free/polarizer assembly and lamp are sealed inside the metal optical tube.
· The aperture dial is mounted to the metal optical tube to maintain precise alignment even if the instrument is dropped of otherwise misused.
