The **0-4D3-R2** is a specific part number typically associated with **MKS Instruments / Newport**, often used in the context of high-precision optical mounts or motorized stages. In most engineering databases, this prefix refers to a **Newport 0.5-inch (12.7 mm) Diameter Optical Component Mount** or a similar sub-assembly. Below is a breakdown of the technical aspects and electronic integration of this component. --- ## Technical Specifications & Characteristics | Feature | Description | | :--- | :--- | | **Component Category** | Optomechanical / Opto-electronic sub-assembly | | **Material** | Aluminum (Anodized) or Stainless Steel | | **Diameter Support** | 0.5 inch (12.7 mm) | | **Motion Type** | Kinematic adjustment (Pitch/Yaw) | | **Resolution** | Sub-arcsecond (depending on the actuator used) | ### Electronic Integration While the "0-4D3-R2" itself is a mechanical housing, it is frequently integrated with electronic actuators to become a "smart" component. 1. **Piezoelectric Actuators:** Often retrofitted with piezo stacks for high-speed, nanometer-scale adjustments. 2. **DC Servo/Stepper Motors:** Can be used with Newport's **Picomotor™** technology, which uses electronic pulses to drive high-resolution screw movements. 3. **Feedback Loops:** In advanced setups, the mount is paired with a Position Sensitive Detector (PSD) to create an electronically controlled closed-loop alignment system. --- ## Part Number Breakdown (Generic Industry Mapping) | Segment | Meaning | | :--- | :--- | | **0** | Series or specialized size indicator (0.5"). | | **4D3** | Specific geometry/design code for the mount body. | | **R2** | Revision number or specific coating/material variant. | ### Common Applications * **Laser Cavity Alignment:** Electronic control of mirror positions for beam stabilization. * **Fiber Optic Coupling:** Fine-tuning the entry point of light into a fiber core. * **Automated Lab Sequences:** Used in experiments where remote manual adjustment is impossible (e.g., inside a vacuum or radiation chamber). --- ## Maintenance and Installation Notes * **ESD Sensitivity:** If the "R2" variant includes integrated sensors, ensure Grounding procedures are followed. * **Voltage Requirements:** If using the electronic version (Picomotor), it typically requires a **900V-1200V pulse** at low current, requiring a specific controller. * **Mounting:** Standard 8-32 or M4 threaded holes for integration into optical tables.
