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.
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.
Isolated IR source and large space heat dissipation chamber design provides higher thermal stability. Stable interference is obtained
without the need of dynamic adjustment.
High intensity IR source adopts a reflex sphere to obtain even and stable IR radiation. Cooling fan stretch suspending design ensures good mechanical stability.
Super wide sample compartment provides more flexibility to accommodate various accessories.
The application of programmable gain amplifier, high accuracy A/D converter and embedded computer improves the accuracy and
reliability of the whole system.
The spectrometer connects to PC via a USB port for automatic control and data communication, fully realizing plug-and-play operation.
Compatible PC control with user friendly, rich function software enables easy, convenient and flexible operation. Spectrum collection,
spectrum conversion, spectrum processing, spectrum analyzing, and spectrum output function etc. can be performed.
Various special IR libraries are available for routine search. Users can also add and maintain the libraries or set up new libraries by
Accessories such as Defused/Specular Reflection, ATR, Liquid cell, Gas cell, and IR microscope etc can be mounted in the sample
