Iris diaphragms
Description
Iris diaphragms are commonly used in optical systems to control light-throughput or f/number. The diaphragms in our range have blackened brass bodies and blackened steel leaves. The IZ fully closing types have two sets of leaves that overlap on closing thus completely blocking the beam. As the sets of leaves are longitudinally separated, these are best used with well-collimated light.
