SINE M-19 Sinusoidal Array

The Sinusoidal Array SINE M-19 is a remarkable new test array that achieves 256 cycles per mm while maintaining a significant modulation. It is designed for testing high resolution optical systems such as microscopes. Because its maximum width is 7.5mm, the SINE M-19 is small enough to fit easily onto a standard microscope slide (the TM-G variation is mounted in glass).
