OPTM(UV SR) series

Advances in technology have made the role of nanomaterials even more important. The OPTM series enable more microscopic measurement and study than conventional products. Non-destructive and non-contact testing encourages you to precisely measure coating film thickness and multilayer thin film of optical materials. Also, high-speed measurement within 1 second per point is possible. OPTM series offer you an optimum solution. Software is easy to use for beginners by making optical constant analysis simple.

 Features  
  • High-precision absolute reflectance measurement by microscopic spectroscopy (Multilayer film thickness, optical constant)

  • The functions for film thickness measurement are integrated into the head

  • An optical system that measures a wide wavelength range from UV to NIR

  • Non-contact, non-destructive high-speed micro measurement within 1 second per point

  • Safety mechanism guaranteed by the area sensor

  • A wizard function provided for beginners which enables optical constant analysis

  • Even complex optical constants can be analyzed using Multipoint analysis method

  • A macro function included that allows you to set the measurement sequence

  • A 300mm size stage can be equipped

  • It is customizable
