The Macrospot 1500 is a fiber-optic lighting system which uses 2 flexible tubes to focus pinpoint light on small subjects. This Kaiser Iris Diaphragm for Macrospot 1500 reduces the 67° angle of reflection of the standard fiber-optic light guide to a 38 - 20° range for fine or microscopic work, while it simultaneously reduces the light output by 5 stops. It has a slot for inserting a filter. One Iris Diaphragm is required for each light guide (tube) whose beam you wish to control.
