Shimming in progress
Precision Mounting, Adjustable to the Micron

Our tech specialist Hans Peter Ochsner just fine-tuned a Phase One Digital back for a client, inserting micron-level shims into the adapter and verifying everything on ALPA’s own measurement bench.

We are using a special SchneiderTele-Xenar lens calibrated to 1/100th of a millimeter, together with our proprietary 30,000 CHF temperature-stable glass-fibre bench.
With this setup we can measure and adjust with highest precision.
Like a swiss watch, a service of your ALPA Camera is recommended every 3-5 years, depending on the conditions in which you use the camera. A service includes servicing the bearings, the rollerbearing guides, adjusting the camera movements, calibrating the Digital Back, cleaning the camera.
If you feel your camera needs revision, do not hesitate to contact us!
