【Simple Operations】: Desktop polarising microscope with integrated light source, powered by AC supply, delivering sustained optimal illumination. Lenses may be placed directly onto the lens holder for observation, ensuring straightforward operations.
【Stress Tester】: Enables observation of light and dark striations on lenses, force distribution during injection moulding, detection of assembly force variations, and differentiation between genuine and counterfeit crystal lenses.
【Rotating Polarising Disc】: Enables observation of light and dark striations on lenses, force distribution during injection moulding, detection of assembly force variations, and differentiation between genuine and counterfeit crystal lenses.
【One-Button Operations】: Button-controlled operations, plug in and switch on for immediate use. Energy-efficient and power-saving, simple operations, highly efficient and rapid.
【Application Scenarios】: Suitable for major opticians, optometric centres, hospitals, optometry training centres, and similar establishments. Used for detecting eyewear stress conditions, authenticating crystal lenses, and applicable for eyewear production and inspection.
Operating Instructions:
(1) Switch on the stress tester and activate the power supply
(2) Position the lens to be tested between the analyser and polariser
(3) Observe the stress distribution around the lens within the lens ring from above the analyser to assess stress uniformity and identify areas requiring correction
(4) Place the corrected spectacles on the stress tester, re-measure the stress value to confirm successful adjustment.
