The origins of Aabspec go back to 1975 and the development of new methods for GC-IR,
including the invention of the first high performance short light-pipe. Since then, the company has
responded to the special needs of spectroscopists in many research areas. The objective has always
been to offer something special through new technology, pushing the limits of experimentation.
Consequently, Aabspec products have opened up entirely new areas of research for government,
university and industrial customers throughout the world. Techniques pioneered include ultra-high
temperature spectroscopy for solids, extending the high-temperature/high pressure range for fluids,
improved optical collection for variable temperature/pressure Raman microscopy and precision
dual-sample comparative spectoscopy.
Chief Spectroscopic Techniques Supported
Aabspec's products support ultra-high temperature spectroscopy (to 950o
C for solids/450oC for fluids); low-temperature spectroscopy
(to -170oC); high pressure spectroscopy (to 10,000psig);
vacuum spectroscopy (to 10-8torr); transmission, specular and large
angle reflectance; irradiation (UV, etc); Raman; GC-FTIR; TGA-FTIR; LC-FTIR; GPC-FTIR;
direct-evolved gas analysis -FTIR; SFC-FTIR; variable temperature/ variable pressure FTIR
microscopy; dual-sample comparitive spectroscopy; Raman microscopy and special application
products. The company's products cover IR, near-IR, Far Infrared, VIS, and UV optical ranges
All international markets for advanced spectroscopic products are served, including special product
design to customer specification. Most Aabspec customers are engaged in advanced research.
Aabspec products are in use in more than 25 countries around the world. Outside the U.S. and
Canada, marketing is handled by Aabspec International Ltd. (Ireland).
All products are designed to be user installable. We provide ongoing support and technical advice plus upgrade designs and
special add-ons for specific customer applications.

Aabspec designs and manufactures all hardware and electronics in-house. We operate our own
machine shop with computer based machining using leading U.S. manufactured machine tools. This
has enabled us to develop a range of special machining techniques for stainless steel and other
materials to eliminate the use of welds in any of our products and ensure exceptional quality.
