imatest VisNIR Dynamic Range Chart——Conforms to IEC 62676-5 standard. Can be used to test SNR, Dynamic Range, grey scale response and other parameters.

The Imatest 36-Patch Dynamic Range test charts on VisNIR film have two density ranges to suit every need. The charts allow you to measure the tonal response, noise, and dynamic range of various imaging systems with a single image instead of multiple, exposure bracketed images. The varied tone background density enables proper exposure with automatic exposure cameras and minimizes unwanted stray light influence. VisNIR Film allows for stable attenuation across visible and Near Infrared wavelengths. Ideal for multispectral systems. VisNIR Film is spectrally neutral and achromatic which allows for stable attenuation across visible and Near Infrared wavelengths without any color cast. Ideal for multispectral systems.
