The LE7 contains two, four or six iQ-LED elements* and is based on the principle of an integrating sphere to provide > 97% uniformity of the active chart area.

This product 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 LE7. Version 3.2.0 and above gives you the capability to control individual modules. Controlling modules individually provides the opportunity for a more extensive intensity range.

An iQ-LED API is also available as a separate option for integration into your design.

LE7 VIS-IR – Adjustable light extending to the VIS-IR spectrum

In the LE7 VIS-IR version, two iQ-LED V2 elements cover the visible spectrum and four iQ-LED VIS-IR elements with 11 channels are in the near-infrared region. These extra VIS-IR elements extend the spectral range from 380 – 1050 nm. The control software and API do not change.

LE7-E

The LE7-E version gives you the possibility to create a dynamic range of up to 1:100.000. Such a wide dynamic range greatly expands the testing possibilities especially when testing in low light. This particular version is currently the only iQ-LED device that can reach such a wide dynamic range.

This version uses six iQ-LED modules with the top center module covered with a 1.8 ND filter making it suitable for low light testing down to 0.25 lx making it ideal for low light testing. If you are measuring extremely low intensities, we recommend using an external radiolux (as opposed to the internal mini-spectrometer) to ensure you have exact values when measuring at these low intensities.

The LE7-E requires iQ-LED software version 3.2.0 or above to function effectively. With version 3.2.0, you can now control single modules inside the same device. Controlling single modules is essential for creating a larger intensity range especially when using low light.

LE7 with camSPECS plate

The camSPECS plate is a uniquely designed transparent plate for spectral sensitivity measurements and camera color calibration. The plate is designed after the front plate of the camSPECS device with all of the interference filters mounted onto one “test chart” for more efficient spectral sensitivity measurements.

The camSPECS plate has been developed as an option to use with the LE7 for uniform iQ-LED illumination. iQ-LED illumination (as opposed to the halogen light source in the camSPECS device) can generate custom spectra to replicate numerous light sources for camera characterization and calibration.

The plate can be used with any LE7 version or variation. An external calibration device is included with the plate. Please contact us for details.

*Please note, we may be able to upgrade your exisitng LE7 V2 without having to order a full new device (not guarenteed). Please contact our sales team for detials.

LE7 包含兩個、四個或六個 iQ-LED 元件*，基於積分球原理，可提供 > 97% 的有效圖表區域均勻性。

該產品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。

LE7 隨附 iQ-LED 控制軟件。3.2.0 及以上版本可讓您控制單個模塊。單獨控制模塊可實現更廣泛的強度範圍。

您還可以單獨選擇 iQ-LED API，將其集成到您的設計中。

LE7 VIS-IR–可調光延伸至 VIS-IR 光譜

在 LE7 VIS-IR 版本中，兩個 iQ-LED V2 元件覆蓋可見光譜，四個 iQ-LED VIS-IR 元件的 11 個通道覆蓋近紅外區域。這些額外的 VIS-IR 元件擴展了 380 – 1050 nm 的光譜範圍。控制軟件和應用程序接口不變。

LE7-E

LE7-E 版本的動態範圍可達 1:100.000。如此寬的動態範圍極大地擴展了測試的可能性，尤其是在弱光環境下進行測試時。該版本是目前唯一能達到如此寬動態範圍的 iQ-LED 設備。

該版本使用了六個 iQ-LED 模塊，中間的頂部模塊覆蓋有 1.8 ND 濾光片，適合低至 0.25 lx 的微光測試，是微光測試的理想之選。如果您要測量極低的光強，可以使用 iQ-LED 測試儀。

LE7-E 需要 iQ-LED 軟件 3.2.0 或更高版本才能有效運行。使用 3.2.0 版，您現在可以在同一設備內控制單個模塊。控制單個模塊對於創建更大的強度範圍至關重要，尤其是在使用弱光時。

帶有 camSPECS 板的 LE7

camSPECS 板是一種設計獨特的透明板，用於光譜靈敏度測量和相機色彩校准。該板是按照 camSPECS 設備的前板設計的，所有干擾濾光片都安裝在一個 “測試圖 “上，以便更有效地進行光譜靈敏度測量。

iQ-LED 照明（與 camSPECS 設備中的鹵素光源不同）可生成定制光譜，以複製用於相機鑒定和校准的多種光源。

該板可用於任何 LE7 版本或變體。校准板隨附一個外部校准裝置。詳情請聯繫我們。

*請注意，我們可能可以升級您現有的 LE7 V2，而無需訂購完整的新設備（不保證）。詳情請聯繫我們的銷售團隊。
