The Model 308 UV Light Meter is used in Photolithography, MEMS, 3D Printing, Packaging, and UV Curing & Sterilization. Accuracy of this UV Light Meter is within ±3% and measurement repeatability is within ±3 LSB (least significant bit). Like all OAI precision instruments, the Model 308 provides NIST traceable measurements. This easy-to-use light meter is auto-ranging from 0.1 to 1999.9mW/cm² full scale when used with the 2000mW/cm² probe. The linearity of the UV Light Meter in this range is at least ±.002%-6 LSB.

Power for the Model 308 Light Meter is supplied by a 9V alkaline battery and the easy-to-read LCD display consumes very little power for extended battery life. This easy to use, handheld UV Light Meter features a peak hold switch enabling the user to capture the maximum intensity reached during an exposure while retaining the reading on the display. OAI maintains a Calibration Laboratory to ensure that all products continue to meet specifications.

The Model 308 UV Light Meter is available with a family of calibrated detachable probes having spectral responses peaked in the UVA range at 365nm, 380nm, 400nm, 420nm, 436nm, and 540nm, the UVB range at 310nm and UVC range at 220nm, 253.7nm, and 260nm. Each detachable probe employs an ultra-stable silicon detector and special filters that precisely shape the spectral response. For added ease-of-use, probes are calibrated for direct reading without any additional adjustment. In cases where the measurements are to be performed in environments having significant infrared (IR) radiation levels, OAI can supply an optional high-intensity, high-temperature, detachable probe.

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.

The OAI UV LED Light source delivers a beam size of between 4″ and 12″ with beam uniformity better than ±4%. It features a prism array and light pipe for superior uniformity.
