iQ-LED V2 technology is a light source that can generate custom spectra to replicate various light sources in a test lab environment. The CAL3-XL uses four iQ-LED V2 elements as opposed to just one that the normal CAL3 uses. Each unit contains 20 LED channels to emulate almost any light spectrum for your camera testing.

Apart from having more iQ-LED elements, the CAL3-XL is also much larger in size and contains a wider bowl diffuser to permit easier evaluation of larger cameras with wide-angles.

Similar to the original CAL3, the XL version is primarily used for camera calibration, determining defective pixels, exposure adjustment, and luminance and color shading measurement. Where the XL version differs, of course, is its ability to more efficiently test much larger cameras and lenses.

The CAL3-XL uses a mini-spectrometer with high spectral resolution, and a spectral range of 350 – 860 nm.

iQ-LED control software is included with the device. We also offer an iQ-LED API as a separate option.

iQ-LED V2 技術是一種可以生成定制光譜的光源，用於複製測試實驗室環境中的各種光源。CAL3-XL 使用四個 iQ-LED V2 元件，而普通 CAL3 只使用一個。每個單元包含 20 個 LED 通道，幾乎可以模擬任何光譜，用於相機測試。

除了擁有更多的 iQ-LED 元件外，CAL3-XL 的尺寸也大得多，並包含一個更寬的碗狀擴散器，以便於對較大的廣角相機進行評估。

與最初的 CAL3 類似，XL 版本主要用於相機校准、確定缺陷像素、曝光調整以及亮度和色差測量。當然，XL 版本的不同之處在於它能更有效地測試更大的相機和鏡頭。

CAL3-XL 使用的微型光譜儀具有很高的光譜分辨率，光譜範圍為 350 – 860 nm。

該設備隨附 iQ-LED 控制軟件。我們還單獨提供 iQ-LED API。
