The **VS-H5-R** is a high-precision, small-aperture fixed focal length lens (often referred to as a "Machine Vision Lens") manufactured by **VST (Variable Optical Kyodo Co., Ltd.)**. While it is primarily an optical component, its electronic integration and specifications are critical for automated imaging systems. --- ## 1. Technical Specifications Below are the key technical parameters for the VS-H5-R: | Parameter | Specification | | :--- | :--- | | **Focal Length** | 5.0 mm | | **Max Aperture (F-Stop)** | F1.4 - F16 | | **Sensor Support** | 2/3" (Standard) | | **Mount Type** | C-Mount | | **Filter Thread** | M40.5 P=0.5 | | **Operation** | Manual (Iris & Focus) | --- ## 2. Electronic Integration Components Though the lens itself is manual, it functions as the "eye" for the following electronic parts within a vision system: ### A. The Image Sensor (CCD/CMOS) The VS-H5-R is designed to project light onto an electronic sensor. * **Format Compatibility:** Optimized for 2/3" sensors but compatible with smaller 1/2" or 1/1.8" formats. * **Resolution Power:** Engineered to resolve high-megapixel counts (often up to 5MP or 10MP depending on the specific series version), ensuring the electronic sensor receives a sharp signal. ### B. The C-Mount Interface The "C-Mount" is the mechanical-electronic standard for connecting the lens to a camera body. * **Flange Back Distance:** 17.526 mm. This precise distance is required for the light to hit the electronic sensor's plane perfectly in focus. ### C. Locking Screws (Industrial Stability) Unlike consumer lenses, the VS-H5-R features **manual locking screws** for both focus and iris. * **Purpose:** Prevents shifts caused by industrial vibrations, which would otherwise cause "noise" or errors in the electronic image processing software. --- ## 3. Key Features for Electronic Systems 1. **Low Distortion:** Crucial for electronic "Pattern Matching" or "Measurement" software. If the lens distorts the image, the electronic calculations for part dimensions will be incorrect. 2. **High Contrast:** Enhances the signal-to-noise ratio for the camera's ADC (Analog-to-Digital Converter), making it easier for the system to distinguish edges. 3. **Compact Design:** Designed for tight integration inside electronic control cabinets or robotic arms. --- ## 4. Usage in Automated Systems In a typical setup, the VS-H5-R works in tandem with: * **Industrial Camera:** Captures the light. * **LED Controller:** Provides synchronized strobing light. * **PLC/PC:** Processes the electronic data via GigE, USB 3.0, or CameraLink interfaces.
