iQ-LED V2 technology is a light source that is capable of generating custom spectra to replicate various light sources in a test lab environment. The CAL2 has one iQ-LED V2 element built into it that uses 20 LED-channels to recreate almost any light spectrum for your camera testing.

The CAL2 has a unique design for easily integration into production lines as well as other testing areas or labs where space is limited. The spectrometer used for calibrating the CAL2 is separate from the light source (where as in our other CAL products, it is built-in) so that a single spectrometer can calibrate separate CAL2 devices to save space. This feature is especially important for production line calibration. Even without an integrating sphere design, this device still achieves uniformity of > 96%.

The 60 mm x 60 mm opening of the CAL2 allows certain devices such as cellphones to calibrate multiple camera modules at one time. If the image processing of the camera is fast enough, a complete camera calibration can be done in less than a second. There is also a new diffuser plate that has better Lambertian characteristics as opposed to the first generation-device.

Other benefits of the CAL2 include:

• Exposure adjustment
• Detection of defect pixels
• Determining luminance and color shading measurements
• Checking the auto white balance under various light sources (i.e., A, C, D50 D55, D65, D75)
• Sepctral sensitivity measurement with module-based color corrections

The CAL2 uses a mini-spectrometer with a spectral range of 350 – 860 nm to ensure better spectral resolution and higher sensitivity.

iQ-LED control software is provided with the CAL2. An iQ-LED API is also available as an option for integration into your custom design.

iQ-LED V2 技術是一種能夠生成定制光譜的光源，可在測試實驗室環境中複製各種光源。CAL2 內置一個 iQ-LED V2 元件，可使用 20 個 LED 通道為相機測試重現幾乎任何光譜。

CAL2 設計獨特，可輕鬆集成到生產線以及空間有限的其他測試區域或實驗室中。用於校准 CAL2 的光譜儀與光源是分開的（而我們的其他 CAL 產品則是內置的），這樣一台光譜儀就可以校准不同的 CAL2 設備，從而節省空間。這一功能對於生產線校准尤為重要。即使沒有積分球設計，該設備的均勻性仍能達到 96% 以上。

CAL2 的開口尺寸為 60 毫米 x 60 毫米，允許某些設備（如手機）一次校准多個相機模塊。如果相機的圖像處理速度足夠快，整個相機校准過程可在一秒內完成。此外，與第一代設備相比，新的擴散板具有更好的朗伯特性。

CAL2 的其他優點包括

• 曝光調整
• 檢測缺陷像素
• 確定亮度和色差測量值
• 在各種光源（如 A、C、D50、D55、D65、D75）下檢查自動白平衡
• 利用基於模塊的色彩校正進行光譜靈敏度測量

CAL2 使用一個光譜範圍為 350 – 860 nm 的微型光譜儀，以確保更好的光譜分辨率和更高的靈敏度。

CAL2 隨附 iQ-LED 控制軟件。還可選配 iQ-LED API，以便集成到您的定制設計中。
