Cleaning Phase Masks with First Contact™ Polymer Solution
Phase masks are difficult to clean. Traditional methods are time consuming and require hazardous chemicals. First Contact™ simplifies cleaning phase masks and ensures excellent results.

Simply apply a generous amount of First Contact™ to the phase mask and allow it to dry. If the contaminants are only particulates the application rate may be as little as 1 ml for each 3.5 square inches, 22.5 square centimeters; but if there are skin oils or fingerprints use 1 ml for each 2 square inches, 13 square centimeters. When lifting oils from a contaminated phase mask it is helps to place a cover over the treated optic to slow down the drying process and allow it to dry overnight. If the oily contamination is heavy, it may help to rinse with an organic solvent prior to using First Contact™.
