Diffuse/Specular Reflectance Accessories : It is a versatile diffuse reflectance and specular reflectance accessories. Diffuse reflection mode is used for transparent and powder sample analysis. Specular reflection mode is for measuring smooth reflective surface and coating surface.

  • High light throughput.
  • Easy operation, no internal adjustment needed.
  • Optical aberration compensation.
  • Small light spot able to measure micro samples.
  • Variable angle of incidence.
  • Fast change of powder cup.

Horizontal ATR/ Variable Angle ATR (300– 600) : Horizontal ATR is suitable for the analysis of rubber, viscous liquid, large surface sample and pliable solides etc. Variable angle ATR is used for measurement of films, painting (coating) layers and gels etc.

  • Easy installation and operation.
  • High light throughput.
  • Variable depth of IR penetration.

IR Microscope

  • Micro sample analysis, minimum sample size : 100µm (DTGS detector) and 20µm (MCT detector).
  • Non-destructive sample analysis.
  • Translucent sample analysis.
  • Two measurement methods : transmission and reflection.
  • Easy sample preparation.

Single Reflection ATR : It provides high throughput when measuring material with high absorption, such as polymer, rubber, lacquer, fiber etc.

  • High throughput
  • Easy operation and high analytical efficiency.
  • ZnSe, Diamond, AMTIR, Ge and Si crystal plate can be selected according to application.
