Digital light meter 458

UV

The microprocessor based Model 458 UV Light Intensity & Energy System accurately profiles exposure energy (dose) to assess the performance of the stepper. It is designed for use with the ASML High Intensity, Canon, Nikon, and Ultratech High Intensity Wafer Steppers. Reads intensity, energy, and time (4000 mW/cm², 999.9 mJ/cm²) for 365, 400, 420, and 436 nm wavelengths. Optional RS232 cable available to work with the 458 software to send dose data to a computer.APPLICATION Perfect for a wide variety of industries where the precision measurement of UV energy is essential, the Model 458 is designed for any application requiring repeatable, reliable UV measurement. HARDWARE FEATURES Averages up to 9 exposures Digital display provides clear, NIST traceable measurements Measures Intensity, Time, and Energy Records % deviation over a series of exposures Probe wavelength display helps prevent errors in setup Simple push button operation provides reliable results RS 232 output to download and record analyzer measurement results Detachable probes to match the spectral response of many photoresists Display readings can be frozen Front panel reminders prompt the user Rugged aluminum case features handle and probe pouch for portability
