O-Tool | Device for measuring the modulation transfer function of photo lenses or similar systems
The IB(E Optics O-Tool is a versatile and compact device for measuring the modulation transfer function of photographic lenses or similar systems at an infinite object distance. The measurement is carried out in real time at the three typical spatial frequencies 10lp/mm, 20lp/mm and 40lp/mm (line pairs per millimeter). In addition, a system can be examined at any user-defined frequency.
