Frequently Asked Questions
Which microscope bodies does it accept?
The product summary and specification table list SSZ, SPZ, DSZ and NSW series bodies. Confirm your exact microscope's fit against the 74 mm ring.
Which stands can it mount on?
Aven describes mounting the E-Arm on its boom stands or articulating arm stands. Verify the 15.875 mm (5/8-inch) connection for your intended configuration.
How much focusing travel does it provide?
Aven lists 50 mm of vertical focusing travel. This is mount travel, not the optical working distance of the microscope.
Does it have fine focus?
Aven's details and features describe coarse focus, while its specification table lists coarse and fine. Confirm fine-focus availability with Aven if that feature is essential to your purchase.
What is included?
The specification lists one E-Arm. A stand, microscope body and lighting package are not listed as included.
Is this a tiltable arbor assembly?
The supplied information identifies an E-Arm focus mount and does not specify tilt adjustment. Select a configuration explicitly described with a tiltable arbor if microscope-body tilt is required.
