PIFOC® QuickLock Thread Option

Installation instructions

Introduction

This technical note describes the assembly/disassembly and installation/deinstallation of P-726
PIFOC® microscope objective nanofocussing positioners and scanners with the QuickLock
feature.

The QuickLock feature was developed to allow use of the same PIFOC® unit with any of the
supported microscope and objective thread types. Previous PIFOC®s could each be used only
with a single microscope thread size.

All QuickLock PIFOC®s can be installed without rotating the unit, eliminating inconvenient cable
windup.

Note that PIFOC
included with QuickLock adapters.

®

s and QuickLock adapters have to be ordered separately. Mounting tools are

Design

The QuickLock thread option provides interchangeable insert rings with matching threads for
the microscope and the objective. The objective ring accepts the microscope objective and is
screwed into the PIFOC® body (the required flat wrench is provided). The turret ring is screwed
into the microscope and is clamped to the PIFOC® body under the knurled ring.

NOTICE

Possible damage due to excessive torque!

Only moderate torque is necessary to secure the objective ring in the PIFOC® body.

 Only use the included flat wrench for tightening the objective ring.

PIFOC® QuickLock Thread Option

The QuickLock adapters are available with apertures of different inner diameters:

shown). Use the narrow face of the flat wrench to engage the wrench slots in the ring.
Grip the tool by hand only.

4. Affix the PIFOC® to the microscope: Align the PIFOC® with the knurled ring and screw

the knurled ring onto the PIFOC®.

Disassembly

1. Remove the PIFOC® from the microscope (not shown): Hold the PIFOC® by the base

body with one hand and unscrew the knurled ring from the PIFOC® with the other hand
as shown in the figure below.

Figure 8: Unscrewing the knurled ring

If the turret ring needs to be removed from the microscope, use the narrow face of the

flat wrench to unscrew the ring from the microscope (not shown). Grip the tool by hand
only.

3. If the objective needs to removed, unscrew it from the PIFOC® body. The objective ring

will probably remain in the PIFOC®.

Figure 9: Objective installed in PIFOC®

If the objective ring is still in the PIFOC® and needs to be removed, use the wide face of

the included flat wrench to unscrew the ring from the PIFOC®. Grip the tool by hand
only.
