The Qool Rail 250 is an excellent choice for studio focus stacking work. It is capable of up to 100x magnification. The minimum step size for this rail with 2mm pitch screw is 0.078125 μm (yes, it's really μm, so 0.000078125 mm) with micro stepping controller (such as our USB and IR Remote controller), but practical step size is 0.3125 μm as we do not have equipment to test further.

The rail is fully assembled, tested and fine tuned.

The USB version comes with the following:

- Black anodized QOOL 250 Rail with 2mm pitch screw and MJKZZ USB Controller
- Nema 23 1.8 degree bi-polar step motor
- High quality membrance coupler
- 60mm round Arca-Swiss camera clamp with positioning poles
- Power Supply
1x Camera shutter cable of choice (see options below)

If you need something to fix it on the table, we recommend you to add two 25cm long aluminium rails to your order. Connectors will be included for the QOOL rail automatically.
