Adjustment Screw, 100 TPI, 25.4 mm, Small Knob, Side Lock, Pack of 10

This is a 10-pack of the Adjustment Screw. The AJS100-1 Adjustment Screw has precision rolled threads for exceptionally smooth adjustment and higher sensitivity than standard micrometers. The AJS100-1 offers 1 inch (25.4 mm) precision travel obtained with included small adjustment knob, ideal for use with Newport optical mounts, stages, and most micrometer-compatible components. With sub-micron sensitivity, they are a cost-effective alternative to micrometers where position readout is not required.

High-precision 100 TPI, rolled stainless steel threads are mated with the collet and proprietary lubricant for stictionless movement.

TPI for Every Application

TPI stands for threads per inch and Newport's AJS screws are available in five different thread pitches to cover the sensitivity requirements of every application. Higher TPI provides for a shorter thread pitch with higher sensitivity to a 1° rotation of the adjustment screw. High-precision 254, 170, 127, 100, or 20 TPI, rolled stainless steel threads are mated with the collet and proprietary lubricant for stictionless movement.

Patented Non-influencing Locks

Our patented thread-pitch lock secures the adjustment screw from turning by simply tightening a setscrew. Engaging or disengaging the thread-pitch lock, now standard, won't influence the screw position. Versions with knobs have the lock screw on the side, while hex versions have the lock screw conveniently located on the end next to the drive screw. A single wrench is used for both adjustment and locking. Non-locking, 12.7 mm travel versions are also available for use in optical mounts.

Faster Alignment Times

High TPI adjusters have a clear sensitivity and alignment time advantage. This graph shows the results of alignment time testing of the Ultima Mirror mount with adjustment screws having 80, 100, 127 and 170 TPI.

Sized to Fit Mounts and Stages

Newport's AJS adjustment screws have 9.5 mm industry standard mounting shanks allowing them to fit most optical mounts and linear stages where micrometer heads can be used.

Optional Adjustment Knobs

AJS adjustment screws are offered with a knob or hex adjustment. and stainless steel knobs are available as an accessory for use with the hex adjustment versions. The knobs feature an integral 5/64-in. (2-mm) hex hey for increased adjustment sensitivity.
