ZJS-1.0I Top-Adjusted Optical Mount

ZJS-1.0I provides tilt adjustment and angle locking operated from above for mounting a 1 inch (Ø25.4 mm) optic. The source identifies stainless-steel construction and distinguishes the M4 fine-thread adjustment screws, M4 angle-locking screws and M4 polymer-tipped optic-retention screw. Ø4.5 mm holes in the base secure the mount to its support. Check the optic edge and thickness, base-hole arrangement and space for operating tools before selecting the mount. No SM interface, clear aperture, angular range or accuracy is specified, and these properties are not inferred from appearance or the model name. English artwork illustrates the structure rather than engineering dimensions. Confirm the supplied optic, tools and fasteners, material grade and adjustment performance for the actual order.

Top adjustment and angle locking

Functional photographs label the top M4 fine-thread screws for tilt adjustment and the adjacent M4 set screws for locking the adjusted angle. A demonstration separately shows adjustment from above and locking afterward. Keep these functions distinct. Fine-thread pitch, angular range, resolution and position shift after locking are not specified and cannot be calculated from an M4 label.

Securing the optic

The main image identifies suitability for Ø25.4 mm optics. The dedicated photograph describes a 1 inch set-screw optic opening, while a functional annotation labels an M4 polymer-tipped set screw for securing the optic. This does not establish an SM1 threaded interface or a guaranteed clear aperture. Confirm optic edge geometry, thickness, contact position, permitted preload and any retaining-ring requirement. An optic is not assumed included.

Base mounting

Main and functional images explicitly identify Ø4.5 mm base mounting holes for securing the mount. Photographs show a foot flange with multiple holes but provide no hole spacing, positional tolerances or overall dimensional drawing. Dimensions are not estimated from image proportions. Check base support, fasteners and clearance for operating tools from above.

Material and supplied items

The main image identifies stainless steel but gives no grade, heat treatment, finish or corrosion rating. Although promotional text mentions multiple sizes, this online family currently has one ZJS-1.0I SKU; that phrase does not establish additional configurations. Confirm whether tools, optics and mounting screws are supplied, along with adjustment range, load and delivery.
