ZJJ Height-Adjustable Cylindrical Lens Mounts

The ZJJ family holds rectangular optics between vertically adjustable clamp arms. Four online models provide left-hand or right-hand layouts with two-axis or three-axis adjustment, each confirmed by its dedicated photograph rather than suffix decoding. The source describes mounting a 35 mm high optic, with upper and lower rubber pads protecting the contact surfaces. A taller-optic demonstration uses additional connecting rods, leaving extension supply and stability subject to confirmation. Functional annotations identify M6 × 0.25 adjustment pairs and mounting-hole information but do not specify complete motion definitions, ranges, accuracy or load. Check optic edges, width and thickness, arm orientation, knob clearance and mounting references. English artwork shows the left-hand three-axis structure; other configurations differ.

Handedness and axis options

Four dedicated photographs explicitly identify left-hand two-axis, right-hand two-axis, left-hand three-axis and right-hand three-axis configurations. Handedness refers to the illustrated mount layout and does not establish a particular beam-incidence direction. Select by optical layout, clamp-arm direction and knob access, checking the dedicated image rather than inferring orientation solely from model letters.

Clamp arms and optic height

The main image describes adjustable arms for a 35 mm high optic. Functional annotations show vertical arm adjustment and upper and lower rubber pads intended to protect the optic. A demonstration explains that a cylindrical lens taller than 35 mm can use additional connecting rods and sit between the pads. This is not an unlimited-height guarantee for the standard assembly, nor does it establish that extension rods or optics are included. Confirm width, thickness, clamping force and extension stability.

Adjustment and mounting interfaces

Functional annotations identify M6 × 0.25 fine-thread pairs for tilt adjustment and fore-aft adjustment for three-axis models. They do not define individual coordinates, fore-aft travel or angular range, and pitch is not rewritten as resolution. Another annotation identifies one M4 countersunk hole with M6 threading on each of the two backplates for mount installation. Hole spacing, depth, tolerances and installation orientation are absent.

Supply scope and missing specifications

Black frames, silver rods and gold-colored adjustment collars do not establish material or finish. No overall dimensional drawing, load rating, accuracy, backlash or repeatability data is supplied. Match the rubber-pad contact to optic edges and permissible contact regions. Confirm additional connecting rods, posts, holders, tools and optics separately. English artwork illustrates a left-hand three-axis example.
