Image sensor tests to benefit from new drop-in tuneable LED source
A new turnkey, drop-in calibrated light source for custom and commercially available wafer level testing of CCD and CMOS sensors has been developed by Gamma Scientific from their existing digitally programmable, colour tuneable, RS-7 LED light source.
The new RS-7-4 can deliver virtually any arbitrary spectral power distribution of visible light over a wide range of output luminance. This makes it ideal for accurately characterising a detector’s dynamic range, uniformity, linearity and spectral responsivity.
The RS-7-4 outperforms rival systems due to highly stable DC drive current circuitry that varies the output luminance of manifold discrete LED channels, rather than using pulse width modulation (PWM). This is critical when testing high speed silicon detectors, which can easily time resolve PWM signals and thus give measurement errors.
