ASA 1 is a long type transmission meter for measuring nearly transparent and moulded plastic plates with high sensitivity. By illuminating a sample from its side surface, it is possible to measure the of transparent moulded articles, which was difficult in the past, in the wavelength range of 400nm to 700nm at 20nm intervals.

Depending on sample sizes, two types of optical units are available. This model will exert great power in evaluation of liquid-crystal light guide plates of flat panel displays and other panels.
Key Features
  • Using this model, you can measure the transmission of nearly transparent and moulded plastic plates based on the long spectrophotometry.
  • Measurement of spectral transmittance is available in the wavelength range of 400nm to 700nm at 20nm intervals.
  • Two types of optical units are available for choice depending on your sample sizes. (A type: 350mm x 300mm x 3mm or B type: 550mm x 100mm x 4mm)
  • Various systems of spectral transmittance, L*a*b*, YI, etc. be simultaneously displayed.
  • consists of operation panel, fluorescent character display and built-in printer.
  • Using management software (), analysis measurement data and various graphs is possible on the display of your personal computer.
