@Use of Heat Absorbing Glass

This tube covers the bulb of the bright

Turn the focusing handle of the illuminator
counter-clockwise, and it will be easily released from
the illuminator. Then replace the bulb.

. Use of Iris Diaphragm (slip-in type)

Turn up the Epi illuminator and put the iris
diaphragm on it. If you place a gem on the
diaphragm and match the aderture of the diaphragm
to the size of the gem, switching on the illuminator,

it instantly provides a simple method to examine
the gem.
