Examina-IR System

Features and Benefits

The FTIR600 stage has been adapted from our market leading high precision geology stage to allow infra red analysis of samples from -196 up to 600°C covering all applications from pharmaceutical to polymers.

FT-IR is an increasingly popular method of sample analysis. With today's highly sophisticated instruments combining research quality optical features such as DIC and Phase contrast with IR micro analysis, the FT-IR scopes are some of the most powerful research tools available.

The research possibilities are dramatically increased, by adding a precision heating and freezing stage.

The FTIR600 stage can be mounted horizontally as in IR microscopy setups and vertically for cabinet type IR spectroscopy. The silver block has a tapered hole to allow maximum transmittance of IR without interference. The angle admittance from the condenser is 85° and that of the objective is 116° .

Recycled nitrogen gas is used to purge the stage of moisture and prevent condensation hence enable the capture of clear highly resolved images.

IR transparent window Specifications

The following windows are available from Linkam.

Window Material Transmission wavelength (um) General Properties

BaF2

 0.2 - 11 Insoluble in water, soluble in acids and NH4Cl. Good resistance to fluorides and fluorines. Does not fog.

ZnSe

 0.5 - 20 Insoluble in water, normal acids and bases and virtually all organic solvents. Reacts to strong oxidising agents. Good resistance to thermal and mechanical shock. Suitable for work in temperature range -200 to 800°C

Al2O3

 0.15 - 5.5 Good for high temperature and severe environments. Has high strength, hardness and chemical stability. IR cut off at 5.5um limits its use.
