Product description

These new focus masks made from optical acrylic glass provide 92% transparency.

The imprinted pattern provides a diffraction structure which is around three times brighter than classic metal masks. The acrylic glass masks therefore produce a clearer diffraction pattern and enable focusing with the help of fainter stars.
