This Double layer High Absorbency fabric is super soft and made of super thin fibers. It is used in cleaning delicate surfaces such as space telescopes. The fabric is woven to be non-shedding. Its high absorbency capacity makes it ideal for the surface cleaning of delicates optics. The fabric has also a patented folding design that creates a softer edge compared to a hot sealing process. The swabs are compatible with VDust Plus and Smear Away. DHAP fabrics' patented mini-channels, with contour, provides an even saturation of the paddles surface while preventing pooling and vertical flow at the edge. This reduces streaks associated with traditional flat surface paddles. The mini-channels also provide the extra reservoir to absorb the excessive liquid and prolonging the moisture life of the swab during the cleaning process. For use with the 1.6x sensor size range (16mm).These are softer and more lint-free than the Green Series MXD-100 Swabs. However, DHAP Orange Series swabs are not compatible with VisibleDusts' Sensor Clean.Pack of 12 1.6x cleaning swabs.
