UM1169C Long Reach, Boom Arm, Desk Base, Microscope or Camera Stand
A unique, substantial microscope or camera desk stand with a U-shape desk base. This high quality, highly stable stand has a desk base that is both much lighter in weight than most other stands of this type and it leaves the bench area clear immediately under the stand.  It is designed for looking at large specimens or specimens that need to moved significantly.

This is how it works and how it is assembled:

• The vertical pole is screwed into the U-Shaped Desk Base
• The height locking collar is mounted onto the vertical pole
• The boom arm support assembly is mounted onto the vertical pole
• The boom arm is inserted through the horizontal hole of the boom arm support assembly
• An 'end arbour' pole is inserted into the 'E-Arm' socket at the end of the horizontal boom arm and locked into position.
• A microscope holder or camera/lens holder is mounted onto the end-arbour
• The microscope head is placed into the microscope holder or a camera/lens system is attached to the camera/lens holder
• The 'end' arbour' can be tilted to the desired angle and locked into position.
• The horizontal boom arm can be extended to the desired length and clamped
• The  boom arm and boom arm support assembly can be moved up the vertical pillar to the desired height and locked into position
• The height locking collar is clamped into position under the boom arm support assembly to prevent any downward movement
• The microscope/lens can be focussed using the focus knob on the microscope holder.
• Optional ringlights or gooseneck illuminators can be added.

Optional End Arbours

An ‘End Arbour’ is a high grade steel pole onto which microscope holders (also known as focussing rings) and other devices can be attached.  They are hinged at the top with a clamp so the angle of the arbour and therefore the attached holder can be adjusted.  At the bottom the have a knurled cap which screws into the end, it is removed so that holders can be slid onto the arbour and it is then replaced to prevent any possibility of the holder from sliding off.  At the top they have an ‘E-Arm’ which is a special 5/8th inch diameter spigot (with a recessed clamping section).  This inserts into the end of the Boom Arm (or Articulated Arm) and is firmly clamped into place.  End arbours are available in different diameters, the most common is 25mm and this must match the hole in the microscope holder.
