Product Overview

The CAL3-XL is a calibration light source for cameras with a large field of view (wide-angle). Similar to the normal CAL3 , the CAL3-XL is an integrating sphere that uses iQ-LED technology to generate custom spectra. 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, compared with the normal CAL3's single element. Each unit contains 20 LED channels to emulate almost any light spectrum for your camera testing. In addition to more iQ-LED elements, the CAL3-XL is larger and features a wider bowl diffuser to facilitate the evaluation of larger, wide-angle cameras. Similar to the original CAL3, the XL version is primarily used for camera calibration, detecting defective pixels, adjusting exposure, and measuring luminance and color shading. Where the XL version differs, of course, is its ability to test much larger cameras and lenses more efficiently. 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 an optional add-on.

Key Benefits

iQ-LED light source

The CAL3-XL is an integrating sphere that uses iQ-LED technology to generate custom spectra for more accurate and flexible camera testing.

Wide-angle camera system testing

The CAL3-XL is optimized for calibrating large camera systems with a 180° field of view.

High uniformity

The CAL3-XL achieves >90% illumination uniformity in the active chart area (measured with standard illuminant D65).

Calibrate large camera systems

The CAL3-XL is an integrating sphere with a 500 mm opening diameter for calibrating large camera systems with wide angles.

Luminance and color shading

Our CAL devices can be used to measure luminance and perform color shading measurements.

Software and APIs

CAL3-XL can be controlled using the iQ-LED control software, and we also offer an iQ-LED API.

Use Case

Large Camera System Tests

Many camera systems use wide-angle lenses to capture more of the scene. These lenses are particularly important in the automotive and security industries, where capturing a wider field of view is essential for performance and safety. Typically, these camera modules are smaller and thus can be calibrated with the standard CAL3. However, for other camera systems with much larger lens modules that still require wide-angle testing, we offer the CAL3-XL to calibrate systems with a wider field of view (up to 180°). It uses iQ-LED technology, enabling you to generate custom spectra to simulate almost any real-world light source.
