TH50
AI

The **TH50** typically refers to a high-performance **thermal imaging core** or a specific high-end **thermal scope** (like the InfiRay Outdoor Tube TH50). These devices are complex optoelectronic systems designed to convert infrared radiation into a visible image.
Below is a breakdown of the electronic components and technical architecture of the TH50.
---
### 1. Core Sensor Technology
The heart of the TH50 is the Microbolometer, which detects heat signatures.
| Component | Specification (Typical) | Function |
| :--- | :--- | :--- |
| **Sensor Type** | Uncooled VOx (Vanadium Oxide) | Captures long-wave infrared (LWIR) radiation. |
| **Resolution** | 640 × 512 pixels | Defines the level of detail and clarity. |
| **Pixel Pitch** | 12μm | Smaller pitch allows for higher magnification and a more compact design. |
| **NETD** | ≤25mk to ≤40mk | Measures thermal sensitivity (lower is better for fog/rain). |

### 2. Optical & Electronic Integration
The electronics must bridge the gap between the physical germanium lens and the digital display.
* **Germanium Lens (50mm):** While a physical part, it is coupled with an electronic **focus motor** in high-end models for precision adjustments.
* **Image Processing Engine:** A dedicated SoC (System on Chip) runs proprietary algorithms (like "Ultra-Clear mode") to reduce digital noise and enhance edge contrast.
* **Shutter Mechanism:** An electromechanical component used for **NUC (Non-Uniformity Correction)**, which calibrates the sensor by briefly blocking the lens.

### 3. Display and Output Components
Once the data is processed, it is sent to the user interface.
* **Display Type:** Usually a **Micro-OLED** (Organic Light Emitting Diode) with a resolution like 2560×2560 pixels. OLEDs are used because they operate better in cold temperatures and provide deep blacks.
* **Video Out:** Includes an integrated video encoder for recording (.mp4) and a **Wi-Fi Module** for streaming to mobile devices.
* **Internal Storage:** EMMC or Flash memory (typically 16GB or 32GB) to store footage.

### 4. Power and Connectivity
| Part | Description |
| :--- | :--- |
| **Battery System** | Often a hybrid system: one built-in battery + one replaceable 18500/18650 cell. |
| **Power Management IC** | Regulates voltage to prevent sensor overheating and manages USB-C fast charging. |
| **Interface** | **USB Type-C** for data transfer and external power input. |

### 5. Sensor Array (Auxiliary)
Modern TH50 units contain an **IMU (Inertial Measurement Unit)** consisting of:
1. **Electronic Compass:** For orientation.
2. **Accelerometer/Gyroscope:** For "Auto-off" features and cant-angle detection.
3. **Bluetooth:** For connecting to wireless remote controls or laser rangefinders (LRF).
