Cleaning Diffraction Gratings
Replicated aluminum diffraction gratings are difficult to clean. Traditional methods are time consuming and require hazardous chemicals. First Contact™ simplifies the cleaning process and ensures excellent results.
Formulated to Clean and Protect Phase Masks
- Lifts from nanostructures
- Removes contamination
- Protects diffraction gratings from dust, abrasions,
oxygen, water and water vapor, gaseous sulfur compounds, and fingerprints
- Watch our video when we clean an Ibsen 3000/mm fused silica phase mask. See how the polymer flows into the grating features and replicates the grating structure in the polymer!

Instructions
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 a thick polymer coat will help dissolve the oils. If the oily contamination is heavy, it may help to rinse with an organic solvent prior to using First Contact.
