ZJO-PSM Low-Distortion Stainless-Steel Optical Mounts

The source describes ZJO-PSM as a stainless-steel optic adjustment mount intended to reduce deformation. All eight online models have dedicated photographs labeling two-axis or three-axis adjustment. Each SM05, SM1, SM2 and SM3 interface group offers both options. The documentation follows the explicit image labels rather than deriving unspecified performance from suffixes or model digits. Three-point contact, retaining features and a polymer-tipped set screw come from the main-image functional description; quantified deformation tests are absent. M4 × 0.25 and M6 × 0.25 adjustment pairs are labeled in general examples, but screw pitch is not treated as linear or angular resolution. An M4 countersunk mounting hole and Ø2 mm locating pins also appear in a general image, leaving pin spacing, tolerances and repeatability unconfirmed. English artwork shows a three-control family example. Confirm grade, dimensions, travel, load and supplied accessories for the selected model.

Two-axis and three-axis options

Eight dedicated photographs identify each model as a two-axis or three-axis adjustment option. The 0.5, 1, 2 and 3 inch interface groups each offer both choices. These labels do not by themselves define each motion direction, angular range, linear travel or independence of degrees of freedom. Confirm those details from model-specific engineering information.

Three-point contact and material

A main image describes three-point optic contact intended to reduce deformation and shows retaining features, a polymer-tipped set screw and an open threaded cell. The source title identifies an all-stainless-steel construction but provides no grade, heat-treatment specification or finish. Low-deformation and stability promotions have no clamping load, optic conditions or measurement data and are not converted into quantified guarantees. A pictured optic is not assumed included.

Adjustment pairs and optic interface

The general annotation labels an M4 × 0.25 fine-thread adjustment pair on the 0.5 inch example and M6 × 0.25 on the larger SM1/SM2/SM3 example, describing tilt adjustment with locking. Screw pitch is not converted into optic displacement per turn or angular resolution. SM05, SM1, SM2 and SM3 threaded openings follow their dedicated photographs. Full thread specifications are not borrowed from another product, and nominal optic size is not presented as clear bore.

Installation and supply confirmation

The general image labels an M4 countersunk mounting hole and Ø2 mm locating pins on either side for positioning and mounting-angle setup. Pin spacing, fit tolerances and repeatability are unspecified. A main image states one retaining ring is supplied; confirm its designation, quantity and the supply scope of contact clips and set screws. Check optic edge, thickness, axial space, bottom mounting and allowable preload. Confirm post, optic, accessories, load capacity and actual delivery separately.
