Extended Symphony from Keeler

I first tried out the Keeler Symphony a couple of years ago (Optician 24.05.13) and found much to recommend. I liked the overall design, the gun-metal finish and curves of the base helping the Symphony to stand out.

Perhaps more importantly, for someone involved in training where instruments often need to be transported, the Symphony is very robust and feels solid and durable. The optics of the instrument are excellent – the Galilean converging binoculars offering excellent resolution at high magnification. The image resolution is enhanced by the instrument including an LED light source – I would suggest that LED sources should now be considered the standard for slit lamps. Magnification is available up to 40X (a drum offers 6, 10, 16, 25, and 40X along with a standard 12.5X eyepiece).
