It is bonded to the face of a precision lapped hard anodized aluminum frame which has been optically polished to achieve the absolute ultimate flatness commensurate with the dimensions of the ring. The standard pellicles are stocked uncoated. This results in a Transmission/Reflection ratio of approximately 90/10% throughout the visible and near infrared regions. Other T/R ratios can be achieved by coating for special applications.

These beamsplitters offer the absolute minimum in absorption, distortion, chromic aberration, ghosting and astigmatism due to their extreme thinness.

Each unit is shipped in a protective container and should be handled only by the frame to protect the membrane.
