DW-FTIR-520  FT-IR SPECTROMETER

FEATURES:

l New type cube-corner Michelson interferometer features smaller size and more compact structure, providing higher stability and less sensitive to vibrations and thermal variations than conventional Michelson interferometer.

l Fully sealed damp and dust- proof interferometer, adopting high performance, long lifetime sealing material and desiccator, ensures higher adaptability to the environment and increases accuracy and reliability in operation.  Viewable window for silica gel enables easy observation and replacement.

l Isolated IR source and large space heat dissipation chamber design provides higher thermal stability.  Stable interference is obtained without the need of dynamic adjustment.

l High intensity IR source adopts a reflex sphere to obtain even and stable IR radiation.

l Super wide sample compartment provides more flexibility to accommodate various accessories.

l The application of programmable gain amplifier, high accuracy A/D converter and embedded computer improves the accuracy and reliability of the whole system.

l The spectrometer connects to PC via a USB port for automatic control and data communication, fully realizing plug-and-play operation.

l Compatible PC control with user friendly, rich function software enables easy, convenient and flexible operation.  Spectrum collect, spectrum conversion, spectrum processing, spectrum analyzing, and spectrum output function etc. can be performed.

l Various special IR libraries are available for routine search.  Users can also add and maintain the libraries or set up new libraries by themselves.

l Accessories such as Defused/Specular Reflection, ATR, Liquid cell, Gas cell, and IR microscope etc can be mounted in the sample compartment.

ACCESSORIES

Diffuse/Specular Reflectance Accessory

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

l High light throughput

l Easy operation, no internal adjustment needed

l Optical aberration compensation

l Small light spot, able to measure micro samples

l Variable angle of incidence

l Fast change of powder cup

Horizontal ATR /Variable Angle ATR (30°~ 60°)

Horizontal ATR is suitable for the analysis of rubber, viscous liquid, large surface sample and pliable solids etc.  Variable angle ATR is used for measurement of films, painting (coating) layers and gels etc.

l Easy installation and operation

l High light throughput

l Variable depth of IR penetration

IR Microscope
