NANO Z® patented Z-lift air bearing stages overcome the legacy design issues associated with z-wedges and other vertical stages. They use a novel combination of air-bearings plus two voice coil motors in a compact footprint with up to 50mm travel.
Using air bearings means negligible friction which enables unparalleled accuracy and repeatability down to low double-digit nanometers. Variable counterbalancing easily handles heavy weights like wafer chucks, while still achieving nano-level precision over the full travel range.
The Nano Z® design places vertical force in line with the payload, and this makes it possible to place the stage directly below the payload instead of beside it, avoiding inevitable cantilever inaccuracies and nearly eliminating pitch, yaw and roll.

ALIO’s GeoSymmetric™ Vertical Positioning Stages use voice coil or linear direct drives, high precision crossed roller bearings, and various counterbalance options within a unique and innovative design concept.
Unique geometric shapes provide mounting surfaces on multiple faces of the stage for flexible installation options. Being able to mount the payload directly to the face or top surface of the stage helps to eliminate weakness and resonant frequency issues associated with additional brackets.
The “Symmetric” part of the family’s name originates from the arrangement of the components used. The counterbalance, motor, bearings, and encoder are all placed on an approximate centerline of the stage, i.e. they are integrated in a way that their masses are symmetrically distributed over the stage.
This series of stages has been built for precision with application dependent counterbalances, and has been structurally designed to exceed application performance demands (with bidirectional repeatability down to +/-45nm, travels from 6 to 70mm, and load capacities of up to 30kg). Being 4x to 10x more precise than Z-wedge stages makes ALIO’s GeoSymmetric™ Vertical Positioning Stages great for any application within the semiconductor industry, microscopes for life and health science, or numerous metrology applications.

ALIO’s family of linear motor driven, vertical Z-lift stages are characterized by their low profile and extremely long travel ranges. Using high precision crossed roller bearings and linear encoders, the stages are equipped with magnetic spring counterbalances or a frictionless air bearing pneumatic cylinder. Similar to the GeoSymmetric series of stages, these long travel Z stages have counterbalance, motor, bearings, and encoder all placed on an approximate centerline of the stage. Payloads may be mounted directly to the face of the stage.
The Z-MCB versions with magnetic spring counterbalances allow travel between 25 and 170mm, while the Z-ABCB — with its frictionless air bearing pneumatic cylinder counterbalance — can carry payloads of up to 25kg over 200mm or more.

A broad field of applications from industrial automation to large measurement or metrology tools demand enormous lift capabilities while still achieving nanometer precision. For such applications, ALIO offers vertical Z stages with precision ball screws driven by a frameless torque motor that is equipped with pneumatic release spring engage brakes that lift 20kg without additional counterbalance. For even higher loads, this series offers the so-called “pneumatic boost” option which uses a frictionless pneumatic counterbalance to boost the payload capability to 50kg.
Even with such high loads, these stages can achieve +/- 100 nm bi-directional repeatability over ranges of up to 50mm. This makes it the ideal stage for applications requiring high loads and long travel ranges without compromising precision.

When looking at most imaging applications, optimal focus of the image can only be achieved if the distance between the sample and the optics is adjustable. Typically, a Z-axis focusing stage would be used for such applications with either the sample or the optics being moved along the optical axis. The specifics of the application, the optics, and the sample will ultimately determine the range of motion required, with some examples where additional focus travel is needed being:
• For thick or non-planar samples such as tissue samples or cultured cells
• For non-parfocal objectives each of which have a different focus spacing
• Where there are multiple sample types such as microscope slides or microtiter plates
• When it is necessary to retract the optics during a load/unload operation
Some other advanced microscopy applications require that a series of images are acquired, each separated by a small increment along the Z-axis, such advanced focus control being needed to create 3D sample images.
For all such exacting applications, ALIO’s direct drive focus stage technology is up to the challenge:

ALIO Industries’ linear X stages are the ideal choice for precision applications, as they are commonly used in the precision industry due to their reliability and performance. The family of stages offers a wide range of travel options from 30mm to 300mm by utilizing two types of linear direct drives: the “LM” and the “CM” series.
The “LM” series provides greater force, higher acceleration, greater speed, and supports payloads of up to 50kg, while the “CM” series offers a low-profile design for tools and applications with space constraints, without compromising precision. ALIO’s linear motion systems and linear X stages are the perfect choice for applications that require precision and reliability.

If you need a low-profile solution to avoid space constraints, require different travels in X and Y, and can’t compromise on performance and precision, there are hardly any off-the-shelf products on the market. ALIO’s asymmetrical, monolithic XY stages are unique in the market and can help solve this complex combination of motion requirements.
With linear direct drives, ultra-precise crossed roller bearings, and our 3-plate system, we guarantee highly precise and powerful motion, as well as perfect orthogonality of the X and Y axes in respect to each other.
“Asymmetrical” in this design concept refers to the two different travel ranges of these two stages that are usually achieved by mounting different linear X stages on top of each other.
