Attention

▶ Diaphragm blades of vacuum iris diaphragm acts like a mirror because of no black anodized. Therefore if laser beam is irradiated, a part of incident light will reflect and return to the optical path.
▶ The iris diaphragm is a very delicate mechanism. Pushing or pulling the blades cause malfunction and it cannot be recovered.
▶ Heat from high power lasers may deform the blades and cause them to seize.
▶ Please make sure that open the package in a clean environment and do not touch it with your bare hands.
