Using the Condenser

Using the Condenser

The condenser is furnished with an iris diaphragm, which can be adjusted to match the effective numerical aperture of the

objective

1.To open and close this diaphragm, simply turn the knurled ring on the condenser to the right or left so that the line on the ring is aligned with the objective magnification used.

2.Open the iris diaphragm of the condenser completely at first by turning the conden- ser ring all the way to the right.

Match the line of the rotating ring with the ­objective magnification in use.
