1. Introduction
Thank you for buying a Specac product. We trust it will provide you with
invaluable and excellent service in use.
The Quest Single Reflection ATR Accessory is designed for the
quantitative and qualitative analysis of solids, powders, liquids, pastes
and gum-like samples using mid-IR spectroscopy at a nominal 45°
incident angle under ambient or elevated temperature conditions.
The Quest is based upon Synopti-Focal technology
–
an innovative
synoptic focusing array of highly reflective gold coated mirror only optics
–
in an optical unit fitted with interchangeable ATR puck assemblies
(choice of diamond, ZnSe, Ge or Si). The ATR crystal is mounted in
either a Standard (flat), Liquid or Heated Puck Assembly. For solid
samples, where good contact with the ATR crystal is required, a clamp
arm produces a highly reproducible load of 40 lbs.
The use of mirror optics maximizes the spectral range as follows:

Specular Reflectance measurements are also possible by the use of a
specular reflectance puck at a nominal 45 ° angle.
