The OAI Model 30 UV Light Source (shown with optional stand) consists of a stand-alone light source, constant intensity controller, and shutter timer.

The Model 30 UV Light Source is highly efficient and may be utilized in a variety of applications. Light is collected by an ellipsoidal reflector and focused using OAI’s proprietary optical integrator which produces a highly uniform UV beam at the exposure plane. Using the appropriate lamp (included with the system), this UV Light Source is available in various beam sizes up to 24in² with output spectra ranging from 220nm to 450nm. Output power ranges from 200W to 5kW. All OAI UV Light Sources are equipped with quick-change filter assemblies, enabling the user to customize the output spectrum.

Dual channel feedback circuits control the light source intensity and keep it constant over the lifetime of the lamp. The shutter timer (0.1–.999 seconds) activates the light source shutter. An interface for controlling other shutter speeds is also available.

Model 30E Enhanced UV Light Source

The OAI UV Model 30E Enhanced UV Light Source consists of a stand-alone Model 30 UV Light Source, a constant intensity controller, a shutter timer, and a pull-out drawer with a rotating chuck. Rotating the chuck during flood exposure improves exposure uniformity.

The Model 30E Enhanced UV Light Source is highly efficient and may be utilized in a variety of applications. Light is collected by an ellipsoidal reflector and focused on an integrating/condensing lens array to produce uniform illumination at the exposure plane. This UV light source is available in various beam sizes up to 24in² with output spectra ranging from 220nm to 450nm, using the appropriate lamp (included). Output power ranges from 200W to 5kW. All OAI UV light sources are easily equipped with quick-change filter assemblies, enabling the user to customize the output spectrum with little effort. Optional remote exhaust fans are available.

Dual channel intensity controllers control light source intensity to a user-desired level and keep it constant over the lifetime of the lamp. Controllers feature dual-channel optical feedback, allowing adjustment from one intensity level or spectral sensitivity to another. Intensity controllers feature a visual display for monitoring lamp intensity and power. Range scales automatically for different intensity levels. Audible alarms alert operator when a lamp change is required.

The shutter timer (used with freestanding exposure systems) activates the light source shutter. The timer range is from 0.1 to .999 seconds. An interface for controlling other shutter speeds is available.
