Camera Lenses (Access DH2 with Blue DFK Cameras)
The DH2 has 12mm camera lenses installed in the cameras. These lenses allow for auto focus of
all four slot levels (Top, Middle, Bottom and Base).
The accessory kit contains 16mm lenses. The 16mm lenses can provide improved image
resolution that is useful when working with very fine pitched devices (0.5mm and smaller) in the
lower Prober slots. The 16mm lenses do have a limited focus range and can auto-focus only on
one or two slots without having to manually adjust them. Because of this limitation it is
recommended that the 16mm lenses being used with the Middle, Bottom and Base slots only.
To change the lenses. Remove the two screws that mount the ring light brackets. Replace the
lenses. Reinstall the ring lights. In Workstation, Go to Tools->Options->Hardware and change the
DH2 Lens setting from 12mm to 16mm. Be sure to do a camera offset when changing or focusing
lenses.
