CAL3

The CAL3 is a 0.29 m integrating sphere that uses iQ-LED V2 technology to illuminate a 38 mm concave curved opening. This type of opening as opposed to the flat opening found in CAL1 is ideal for cameras with a wide-angle lens as it supports a 180-degree field of view for the camera under test. A bowl shaped non-reflective diffuser filter on the sphere opening ensures uniformity of > 95%.

CAL3 是一個 0.29 米的積分球，使用 iQ-LED V2 技術照亮一個 38 毫米的凹形弧面開口。與 CAL1 的平面開口不同，這種開口非常適合配備廣角鏡頭的相機，因為它能為被測相機提供 180 度的視野。球形開口上的碗狀非反射漫射濾光片可確保大於 95% 的均勻度。

描述

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 CAL3 has one iQ-LED V2 element built into the back of the sphere, and it uses 20 LED-channels to recreate almost any light spectrum for your camera testing.

As a result of the short response time of iQ-LED V2, a full calibration can be performed in less than a second as long as the image processing and transfer of the camera are quick enough.

The main benefits of the CAL3 include:

Camera calibration of wide-angle lenses
Detection of defect pixels
Determining luminance and color shading measurements
Exposure adjustment
Measuring the spectral sensitivity of multiple devices

The CAL3 uses a mini-spectrometer with a spectral range of 350 – 860 nm to ensure better spectral resolution and higher sensitivity.

iQ-LED V2 技術是一種能夠產生定制光譜的光源，可在測試實驗室環境中複製各種光源。CAL3 的球體背面內置了一個 iQ-LED V2 元件，它使用 20 個 LED 通道為您的相機測試重現幾乎任何光譜。

由於 iQ-LED V2 的響應時間很短，因此只要相機的圖像處理和傳輸足夠快，就能在不到一秒的時間內完成全面校准。

CAL3 的主要優點包括

廣角鏡頭的相機校准
檢測缺陷像素
確定亮度和色差測量值
曝光調整
測量多個設備的光譜靈敏度

CAL3 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。

CAL3 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。

iQ-LED control software is provided with the CAL3. An iQ-LED API is also available as an option for integration into your custom design.
