Model Eye Kit KIT

Demonstration kit comprising a 5 litre round bottom glass flask complete with a cork ring stand, 450g of plastic modelling clay and one each of the following 50mm diameter meniscus lenses:

+11D
+8D
+5.5D
+2.5D
-3D

The first three lenses are fixed to the flask with plastic modelling clay to show short, normal and long sight respectively when a beam of light is passed through them. The other two lenses are used for correcting the long and short sighted condition. The flask is filled with water and a little fluorescein is added (B8A67919 – sold separately) in order to show the path of light through the model eye.

Ideal for use with the LED.white (B8L87348) or a laser.
Fluorescein Sodium Salt is available separately – B8A67919: 5g.
