The Quest ATR Accessory is a performance single-reflection ATR accessory from Specac designed for laboratory spectroscopic sample analysis in the mid- and far-infrared. With innovative optical design and durable monolithic diamond ATR crystal option, this sets the benchmark in performance and value for ATR spectroscopy.

The Quest's innovative optical design is based around all reflective gold-coated optics, and features Specac's Synopti-Focal Array technology with precision-moulded aspheric mirrors. These features allow for a high throughput accessory with an extended wavelength capability suitable for both mid and far-IR spectroscopy.

Four interchangeable ATR crystal pucks are available for the Quest:

  • High throughput diamond 
  • Extended wavelength diamond 
  • ZnSe 
  • Ge 

Each puck is made from hardened stainless steel and are held in place on the accessory magnetically making them easily interchangeable without requiring additional alignment.
