Stepper Motor Compact Translation Stage DOLP-50SX

All JCOPTIX compact stepper stages are rigorously laser-interferometer calibrated before shipment, with factory reports. Separately ordered third-party calibration reports from the Jiangsu metrology institute are available, with accuracy traceable to national length standards. A 30 mm slim design combines micrometer accuracy, nanometer resolution, and 10 kg loads for microscopy, laser micromachining, fiber/waveguide alignment, interferometry, semiconductor inspection, and bioimaging where space is limited. Integrated motors, precision-ground screws, and rigid bearings eliminate conventional couplings to reduce heavy-load backlash and deliver compact high performance. The range includes 2 single X stages with ±12.5 mm/±25 mm travel, 2 XY stages with ±12.5 mm/±25 mm travel, and 1 XYZ with ±12.5 mm XY and 10 mm Z. Single axes combine with DOVP-10S vertical lifts and fit DML90 manual stages, DMV90 manual lifts, and other 90 mm-top products. Crossed-roller line contact supports 2 times the load of same-size ball guides, reaching 10kg horizontal/vertical. Ground screws with DCP-201C provide stable 100nm steps, bidirectional repeatability ±2μm, axial accuracy ≤±15μm, noise <30dB, and continuous stable low-speed motion, described as preferred for compact precision optics.

Factory-matched/debugged stages/controllers perform like separately sold units, with 1 year warranty and technical support, suiting first-time buyers/rapid setups. Controller technical section, DCP-201C. JCOPTIX touchscreen stepper controller DCP-201C has a 2.8-inch color touchscreen and communications/power HUB ports. It drives JCOPTIX stepper optomechanics including linear, vertical, and rotary stages, filter wheels, shutters, and actuators, with 51200 microsteps/revolution. External signals trigger stage motion, or motion generates output triggers for other equipment. It suits on-site control and integration. A mounting plate secures it to optical tables; power supply and USB Type-C cable are included for PC software connection. New PC software supports multiple controllers with independent subwindows for centralized visual management. Built-in sequence control enables coordinated multiaxis motion without further development. Multilingual development interfaces support automated experiments and customization. New JMoition motion-control software supports DCP-201C and multiple stage types. Multiple controllers connect simultaneously, each with its own control/status subwindow. JMotion has built-in sequence editing to configure steps and execute them continuously in order, enabling complex automated motion without further development and making multidevice operation intuitive and efficient for automated experiments and customization. Core-parameter test methods: equipment specifications and DOLL examples, not measured specifications of this model. Stage core parameters. In precision manufacturing, semiconductors, optoelectronic inspection, and research, motion accuracy, stability, and reliability determine quality/efficiency. Test methods/standards define device quality; pitch, yaw, positioning accuracy, and repeatability quantify motion errors. Jiangsu metrology results: JCOPTIX commissioned the Jiangsu Institute of Metrology to test/report stage parameters under 1251-2010, Calibration Specification for Coordinate Positioning Measurement Systems. API XD Laser 6D interferometry measures positioning, pitch/yaw, and other parameters in one setup at 0.5ppm accuracy. Figure 1. Jiangsu institute's stage test report. JCOPTIX test methods: GB/T 11336-2004 procedures use Renishaw XL-80 interferometers and Nuoxu NORMAT1210 precision photoelectric autocollimators. Nuoxu NORMAT1210 measures pitch/yaw over ±1000 arcsec with ±1 arcsec accuracy and 0.2 arcsec repeatability, capturing tiny angular deviations/wobble across a 3800 arcsec × 2800 arcsec field. Segmented measurements and accumulated calculations determine actual-versus-ideal trajectory deviations. Optical accumulation improves accuracy; software directly outputs angles, usually arcseconds or microradians, with lower overall error. 1. Pitch/yaw. (1). Pitch: tabletop rotation θX about the horizontal X axis perpendicular to travel. (2). Yaw: θZ about the vertical Z axis. Figure 2. Pitch/yaw test schematic. 2. Repeatability/positioning accuracy. (1). Positioning accuracy is maximum error from the reference origin to target points over full travel, a key performance indicator. (2). Repeatability usually refers to repeated bidirectional positioning, such as ±X, and actual-versus-set position error over repeated arrivals at one command position, reflecting stability/consistency. Under GB/T 17421.2-2023, JCOPTIX uses Germany's Renishaw XL-80 with multiple target points and repeated forward/reverse arrivals. Actual positions and maximum deviations at each target calculate both repeatability and positioning accuracy. Accuracy is ±0.5 ppm, resolution 1 nm, and stable operation 0-40℃. Environmental compensation corrects temperature, pressure, and humidity, while up to 50 kHz dynamic acquisition captures small motion errors. Figure 3. Interferometric positioning test of precision direct-drive stages. 3. Speed stability. Actual speed fluctuation at a set speed reflects smoothness of control. Renishaw XL-80 dynamic acquisition at 50 kHz records displacement/time during commanded constant-speed travel; software derives speed/fluctuation. For example, JCOPTIX DOLL products over 50~200 mm travel reach 500 mm/s maximum and unloaded acceleration 15 m/s². 4. Homing accuracy. Deviation between the returned and original zero after motion reflects origin stability. Renishaw XL-80 records the initial zero and actual zero after repeated full-travel cycles; maximum deviation is homing accuracy. 5. Minimum achievable and repeatable increments. (1). Minimum achievable increment characterizes the smallest motion step. Renishaw XL-80 measures each actual increment during repeated commanded minimum steps to confirm the achievable minimum. (2). Minimum repeatable increment is the smallest physical step with stable repeatable response, statistically verified and normally no smaller than design resolution. Under GB/T 17421.2-2023, select a random 40 μm segment within full travel, step at the proposed minimum, for example 4 μm, use a 5 μm jump, and repeat 5 cycles. Measured repeatability must be below 20% of the increment, for example 4 μm × 20% = 0.8 μm. Every JCOPTIX motorized stage is tested to relevant standards before delivery and includes a shipment test report.
