See What You Sample – Fast and Easy

The MicromATR Vision™ is an all new product designed to provide the highest available optical throughput in a monolithic diamond ATR accessory.

The small diameter of the crystal broadens the sample range from macro to microsampling. Integrated viewing optics with illumination of the sample through the diamond ATR crystal enables selection of discreet sample features and provides visual proof of sample contact.

ATR sampling with the MicromATR Vision is fast and easy. Elegantly smooth operation of the pressure clamp delivers high and even pressure onto the sample ensuring high quality ATR spectra from even the most difficult samples.

The recommended crystal plate for most applications is diamond – providing a durable, scratch proof sampling surface. The Diamond XR plate provides full mid-IR and far-IR spectral range and sample view through the crystal. The Diamond HT (high throughput) version provides maximum IR signal and highest signal-to-noise ratio (SNR) for the most difficult samples.

Optional crystal plates for the MicromATR Vision include germanium (Ge) for high refractive index samples, Diamond 3X (3 reflection) and Diamond 9X (9 reflection) crystal plates (limited pressure) for low concentration components. Crystal plates are kinematic and easily exchangeable with no alignment, tools or screws required. The MicromATR Vision is also compatible with crystal plates from some other manufacturers.

Heated ATR Crystal Disks and Temperature Controller

The heated ATR disk’s temperature controller is a temperature controller designed to work with both the MicromATR and MicromATR Vision. The controller allows the user to set the disk temperatures up to 130°C in 0.1°C increments.
