Description
Our SINE Sinusoidal Single Frequency transmittance patterns have proved to be very useful for specialized MTF measurements as well as for such applications as Moiré© contouring. They are made on film base material with a thickness of 0.178 mm. This material is polyester and tends to be somewhat birefringent. The harmonic modulation values are generally 3% or less.
A microdensitometer scan is included with each pattern.
Spatial frequencies not listed can be produced on a special order basis. Reflection single frequency patterns can produced for lower spatial frequencies.
