Speckle Reducer

Overview

When a coherent light source illuminates an object, speckle noise appears and degrades your important images. This phenomena occurs due to the coherence of the light and seems to be inevitable.

SK-11 reduces speckle noise and improves your image quality. SK-11 consists of a fiber bundle of different length fibers. The input laser beam with high coherence emerges from SK-11 with lower coherence because the length of the each fiber differs more than the coherent length.

Feature Summary

SK-11 is excellent for microscope illumination. Monochromatic illumination does not cause any chromatic aberration from the objective lens. SK-11 has no moving parts so that you will not suffer from the vibration noise. Scanning system is not required, making it suitable for the temporal resolved imaging.

SK-11 also works as a beam homogenizer. The input Gaussian intensity profile is transformed into a homogeneous profile.
