Introduction
Product Overview
The Torus family of spectrometers offers a unique combination of technologies with a concave grating, a
powerful 2-MHz analog-to-digital (A/D) converter, programmable electronics, a 2048-element CCD-
array detector, and a high-speed USB 2.0 port. Torus is exceptional because it features an aberration-
corrected, holographic, toroidal diffraction grating that delivers low stray light, high throughput and
excellent thermal stability. This makes this family of spectrometers ideal for a wide range of research and
OEM applications such as:
• Detecting trace gas amounts in the atmosphere
• Precision measurement of LEDs, lasers and other light sources
• Absorbance measurement of optically dense solutions
• Fluorescence from solid surfaces
• Medical dosimetry in tissue and other biological media
Our first Torus model is a Visible spectrometer (360-825 nm) whose spectral range and low stray light
make it especially useful for measuring color, while its increased sensitivity and throughput make it ideal
for low light level applications.
The Torus Spectrometer connects to a computer via the USB port or serial port. When connected through
a USB 2.0 or 1.1, the spectrometer draws power from the host computer, eliminating the need for an
external power supply. The Torus can be controlled by our complimentary Overture spectroscopy
operating software as well as SpectraSuite, a completely modular, Java-based spectroscopy software
platform that operates on Windows, Macintosh and Linux operating systems. SpectraSuite is available for
an extra cost.
