IntegratIR – Mid IR Integrating Sphere

Description

PIKE Technologies introduces the Mid-IR IntegratIR™, a new sample compartment accessory with a 3 inch diameter integrating sphere used for the measurement of absolute and relative diffuse reflectance. The Mid-IR IntegratIR features an 8 degree illumination of the sample with an optional specular exclusion optical path. Reflectance samples are placed directly onto the sample port of the upward-looking sphere or over a thin infrared transmitting window. Measurement of diffuse transmission may also be done by placing the sample at the slide mount beam input port.
For optimal performance the accessory includes an integrated and optimized wide spectral range mercuric cadmium telluride (MCT) detector. The accessory comes with built-in detector electronics and can be interfaced to most FTIR spectrometers. The selection of light illumination onto the sample or onto the reference surface is done via a flipper mirror mechanism accessed at the front of the accessory.
The Mid-IR IntegratIR reflectance port is 18 mm in diameter. The accessory can be operated directly with the sphere open, with no light loss – ideal for large, solid samples, or by using the standard ZnSe window – ideal for powdered samples. If preferred, a KBr window can also be used with the sample plate to minimize the reflection loss compared to the ZnSe window.
Diffuse transmittance of partially transmitting materials can also be measured by placing the sample at the transmission station accommodating a standard 2″ x 3″ sample holder.

The IntegratIR is purgeable by connecting the purge line to the front of the accessory, which is directly connected to the sphere assembly for the best purge efficiency.
