Testing panel for surface errors according to DIN ISO and MIL
Testing panel for surface errors according to DIN ISO and MIL

Our testing panels are standards for determining the surface quality of optical components as per DIN ISO 10110-7 and MIL-O-133830A. Surface defects on the components are compared with the markings on the testing panels.

The testing panels made of borosilicate glass with suitable photolithographic markings mounted in a plastic frame. They are supplied in a hard foam case (Plastazote) with clamping lock.

The testing panels are supplied along with a corresponding test certificate.
