2105 C 2 Illumination Controller

Illumination controllers in precision optics are support units that regulate and route light for an associated optical tool. Illumination controllers are generally used to stabilize exposure conditions, manage lamp operation, and provide operator control over the light source used in an optical process.

Illumination controllers generally interface with a lamp or other light source and with the optical system that uses that light. Illumination controllers generally provide controlled electrical drive and user adjustments so the optical tool can produce repeatable illumination at the point of use.

In precision optics service, an illumination controller commonly works as a subsystem rather than as a stand-alone process tool. An illumination controller commonly supports startup, intensity setting, and stable operation of the illumination path used by the paired optical equipment.

An illumination controller fits alongside optical process equipment rather than at a separate material handling stage. An illumination controller supports the optical exposure or inspection function that occurs when light must be delivered in a controlled way to a substrate or imaging path.

Illumination controllers are used wherever a precision optical system depends on consistent and adjustable lighting. Illumination controllers can support photolithography, alignment, microscopy, inspection, and related optical tasks in which light level and stability affect process results.
