In scenarios such as ultra-high-resolution microscopic imaging, laser optical calibration, industrial lens focusing, 3D optical sectioning, and precise optical path calibration, the drawbacks of traditional electrically-powered elevation focusing mechanisms are significant. The conventional mechanical Z-axis focusing relies on screw gear transmission, and is plagued by issues such as return gap, low-speed stalling, mechanical friction jitter, and response lag. Micro-focusing of the lens is prone to over-focusing, focus shift, and repeated out-of-focus phenomena. The residual vibration during equipment operation directly causes image blurring, screen ghosting, scanning distortion, and completely fails to meet the strict requirements of nanometer-level precise focusing, millisecond-level rapid response, vibration-free stable focusing, and high repeatability precision locking for optical lenses. To address the urgent need for precise micro-focusing of optical lenses, Saifan Optoelectronics has launched a dedicated piezoelectric elevation platform for lens adjustment. Based on the piezoelectric frictionless drive architecture, it is specifically designed for precise axial focusing of lenses, completely resolving the accuracy and stability shortcomings of traditional mechanical focusing. It has become the core preferred equipment for high-end optical lenses' precise focusing, high-definition imaging, and other critical requirements.
Exclusive gap-free piezoelectric architecture, suitable for axial lens micro-focusing
The dedicated piezoelectric elevation platform for lens adjustment completely abandons the mechanical friction transmission structures of traditional lens focusing equipment, such as screws, gears, and guide rails. It adopts a piezoelectric ceramic drive + integrated flexible hinge gap-free molding process, focusing on precise vertical-axis Z-axis elevation focusing of optical lenses. From the structural root, it eliminates return gap, transmission stalling, low-speed jitter, and mechanical wear, and perfectly adapts to the high-precision micro-focusing conditions of various optical lenses. The entire machine has an integrated symmetrical layout, with a solid and uniform structure, no lateral shaking or trajectory deviation during focusing, stable and precise lens axial alignment reference, and no need for repeated manual micro-focusing calibration. It completely avoids the problems of deviation in traditional focusing mechanisms, slow response, and poor repeatability, and can accurately complete precise focusing of the lens, focus scanning, optical path axial calibration, and depth of field fine-tuning, etc.
The equipment adopts an ultra-compact and lightweight integrated design, without redundant transmission components, with a small size and excellent adaptability. It does not occupy the limited space of the optical system and can be directly mounted on various microscope objectives, industrial imaging lenses, and laser focusing lenses. The entire machine is dust-free, has no mechanical friction, and does not require lubricating oil. It operates without dust, electromagnetic interference, and does not contaminate optical lenses or affect the stability of the optical path. It perfectly adapts to high-sensitivity working conditions such as clean optical experiments, live-cell microscopic imaging, and high-precision industrial detection. It is equipped with standardized universal installation interfaces, which can be quickly adapted to various optical platforms, microscopes, and automated optical detection systems. It can be used directly without complex calibration and can independently complete single-axis lens focusing, or be combined with XY translation modules to build a complete high-precision scanning imaging system. The flexibility of scene adaptation is maximized.
Piezoelectric ultra-fast precise drive, zero drift in the entire nano-level locking
Millisecond-level rapid focusing, nano-level delicate fine-tuning, and vibration-free stable locking are the core core advantages of the dedicated piezoelectric elevation platform for lens adjustment. The equipment relies on the mature piezoelectric inverse effect drive principle and is equipped with an optimized flexible gap-free guiding structure. The entire process has no mechanical contact friction, uniform and smooth axial elevation feed, extremely fine micro-focusing step distance, and positioning resolution can reach nanometer and sub-nanometer levels. It can accurately capture the tiny focus displacement changes of the lens, completely solving the problems of rough micro-focusing, over-focusing, image jitter, and focus drift in traditional focusing equipment. Whether it is single-point precise locking, small-depth-of-field fine-tuning, or continuous Z-axis scanning imaging, continuous displacement output is stable and balanced, without deviation, drift, or precision attenuation. From the equipment end, it guarantees the clarity of optical imaging, precise optical path alignment, and consistency of experimental data.
The equipment supports open-loop and closed-loop dual-mode precise control. The closed-loop is equipped with a high-precision sensor feedback system, real-time correction and precise locking of Z-axis points, and the lens focusing consistency is extremely strong. Continuing the core advantages of the piezoelectric equipment, it offers ultra-fast response within milliseconds, instant start and stop, no inertia offset, no lag delay, automatic self-locking in static positioning, zero power consumption, effectively eliminating problems such as lens static focus loss, focusing rebound, and point drift. It can be paired with a dedicated motion controller, supporting programmatic and automated trajectory control, and allowing for free setting of focusing speed, fine step size, and scanning stroke, converting the uncertainty of manual focusing into a standardized and replicable optical focusing process. The equipment is resistant to deformation, aged, and operates silently without disturbance, capable of withstanding millions of high-frequency focusing cycles, maintaining stable performance even under long-term regular operation, and perfectly adapting to high-end optical research and precise detection conditions.
