Analytical Instrument Systems, Inc. has developed High Power, High Performance and High Precision power supplies for use with fiber optic spectrometer systems.  These instruments have a built in highly stabilized microprocessor system designed for optimum stability and reflect the company’s understanding of what is needed in fiber optic research.  External computer control can be accomplished using digital levels or via RS232.

A new remote head system, Model DT2000-Rem


Our new remote head system comes in a variety of layouts for your every fiber optic need.  We also have a manually controlled monochromator of the UV side of the remote head system.  This system allows you to connect or use the remote head with all optics separated from the light source power supply thus giving you the greatest flexibility in your fiber optic designs.

A new accessories head allows for the greatest flexibility in fiber optic light sources

Our new accessory system can be used in a variety of applications for your every fiber optic need.  This accessory allows you to manually control an aperture to adjust overall output of power, a cuvette holder for samples or filters, and a port allowing for fluorescence measurements. 

All systems have these basic specifications:
