CAL1

The CAL1 is a 0.3 m integrating sphere that uses iQ-LED V2 technology to illuminate a 70 mm opening for camera testing and calibration. A non-reflective diffusor filter on the sphere opening ensures uniformity of > 98%. This diffusor filter has better Lambertian characteristics as opposed to the first-generation device.

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 CAL1 has one iQ-LED V2 element built into the sphere and 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 CAL1 (and that of our other CAL products) include:

• Camera calibration
• Detection of defect pixels
• Determining luminance and color shading measurements
• Exposure adjustment
• Measuring the spectral sensitivity

The CAL1 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 CAL1. An iQ-LED API is also available as an option (sold separately) for integration into your custom design.
