LE7

The LE7 is a uniform lightbox that uses iQ-LED technology to improve camera image quality testing with transparent test charts.

iQ-LED technology is a light source that is capable of generating custom spectra to replicate various light sources in a test lab environment. As with our other iQ-LED products, the LE7 uses 20 LED channels to emulate almost any light spectrum for your camera testing.

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 achieve better spectral resolution and higher sensitivity.

iQ-LED control software is provided with the LE7. Versions 3.2.0 and above allow you to control individual modules. Controlling modules individually allows a wider intensity range. An iQ-LED API is also available as a separate option for integration into your design.

*Please note, we may be able to upgrade your existing LE7 V2 without having to order a whole new device (not guaranteed). Please contact our sales team for details.

The LE7 is a uniform lightbox that uses iQ-LED technology to generate custom spectra for more accurate and flexible camera testing.

Choose from variants that include 2x, 4x, or 6x iQ-LED modules. Using more modules increases your minimum and maximum illumination values.

The LE7 has a spectral range of 380-820 nm, and the LE7 VIS-IR variant has a range of 380-1050 nm.

The LE7 VIS-IR variant uses two standard iQ-LED modules and four iQ-LED IR modules that expand the spectral range for camera testing in the near-infrared (NIR) range.

The LE7-E variant can create a dynamic range of up to 1:100.00 to expand testing in low-light scenarios.

Using the LE7 with the TE292 camSPECS plate test chart allows you to perform camera color calibrations using the power of iQ-LED technology to increase accuracy.

NIR camera systems have become more prevalent in many industries, including automotive, where they play a crucial role in Advanced Driving Assistance Systems (ADAS) and in-cabin systems for driver and occupant comfort and safety.

With the LE7 VIS-IR, you have a light source that can generate NIR light for more accurate testing of NIR camera systems in the comfort of a test lab.

Measuring a camera's spectral sensitivity determines how sensitive its system is to each wavelength or light level in the visible spectrum.

Traditional measurement methods use a monochromator, but these are complex devices with a steep learning curve. In contrast, LE7 can be combined with the TE292 camSPECS plate for spectral-sensitivity measurements, leveraging the power of iQ-LED technology.

The VIS-IR version of the LE7 provides uniform illumination across the VIS-IR spectrum. This version includes two iQ-LED V2 elements covering the visible spectrum and four iQ-LED IR elements with 11 channels in the near-infrared region. These additional VIS-IR elements extend the spectral range to 380–1050 nm. The control software and API remain unchanged. We also offer many transparent test charts, such as the TE292B VIS-IR (camSPECS plate).

The camSPECS plate has been developed as an option for use with the LE7 to provide 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 spectral sensitivity measurements, camera characterization, and calibrations, particularly color calibrations, including those in the NIR range.

The plate is compatible with any LE7 version or variant. An external calibration device is included with the plate

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 version is the only iQ-LED device capable of achieving such a wide dynamic range.

This version uses six iQ-LED modules, with the top-center module covered by a 1.8 ND filter, making it suitable for low-light testing down to 0.25 lx. If you are measuring extremely low intensities, we recommend using an external radiolux (rather than the internal mini-spectrometer) to ensure accurate measurements.

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 individual modules is essential for achieving a wider dynamic range, especially in low-light conditions.
