SINE (Sinusoidal) Targets & Arrays

The Sinusoidal Pattern Arrays are manufactured on two different materials for either reflective and transmission applications. Because of the inherent limitations of the reflective materials, the maximum spatial frequency is limited to 20 cycles per millimeter while the transmission film arrays are offered in various sizes up to 256 cycles per mm. In addition, the sinusoidal arrays are available in a Single Frequency Grating or with Multi-Frequency Gratings.
