Variable-Angle Reflection Optical Stage (for FTIR)

An all-reflective, variable-angle reflection accessory installed in the sample compartment of FTIR spectrometers. In-situ ATR and external-reflection infrared cells are mounted on this stage for measurement.

The angle of incidence is continuously adjustable from 30 to 80°, so penetration depth and signal intensity can be chosen for each experiment.

Key Features

• Continuously adjustable angle of incidence 30–80°
• Selectable sampling depth with different crystal plates
• High throughput: over 50% with a 45° ZnSe crystal (manufacturer data)
• Penetration depth 0.4–46 µm (depending on crystal and sample, manufacturer data)
• Integrated polariser position; optional pressure clamp for films and powders

Technical Specifications

Please state your FTIR spectrometer brand and model before ordering; compatibility will be confirmed in the quotation.

Dimensions, channel sizes and volume can be customised on request; please state special requirements in your quotation request.

Applications

• In-situ ATR-SEIRAS and IRRAS spectroelectrochemistry
