The Torus Miniature Spectrometer from Ocean Optics is a Visible range (360-825 nm) unit that delivers low stray light and is ideal for measuring color. Its increased sensitivity and throughput also make is perfect for low light level applications. Torus delivers scientific-grade performance with outstanding thermal stability, making is a brilliant choice for a wide range of challenging applications.

For Torus, a variable line spacing grating with 550 (+/-2) grooves/mm groove density at center is used, with a nominal blaze wavelength of 400 nm. This design yields an optical bench in which light can be manipulated more efficiently. The concave grating also helps to improve thermal stability of the Torus. Wavelength drift is nearly eliminated and peak shape stays the same over a wide temperature range. As a result, Torus makes possible precision metrology, fluorescence and absorbance applications with demanding stray light and thermal stability requirements.

Typical Applications
Torus is the perfect solution for a wide range of applications where low stray light, high throughput and thermal stability are necessary:

• Trace gas amounts in the atmosphere
• Absorbance of optically dense solutions
• Precision measurement of LEDs, lasers and other light sources
• Medical dosimetry in tissue and biological media
• Fluorescence from solid surfaces and backscattering/fluorescence in solutions and powders

The Ocean Optics HR4000 Spectrometer is the next-generation high-resolution spectrometer. The HR4000 has a 3648-element CCD-array detector from Toshiba that enables optical resolution as precise as 0.02 nm (FWHM). The HR4000 is responsive from 200-1100 nm, but the specific range and resolution depend on your grating and entrance slit choices. This novel combination of optics and electronics is ideal for applications such as characterizing lasers, measuring gas absorbance, and determining atomic emission lines.

We've put together some guides showing how the HR4000 can be configured in various applications, including for gas absorbance , colour reflectometry , laser analysis, metrology, fluorescence, updwelling/downdwelling, UV/VIS reflectometry and solutions absorbance. Our team of spectroscopists is the most experienced in the industry. We love to talk spectroscopy! Benefit from our knowledge, and call us to discuss your application today.

The QE65000 Scientific-grade Spectrometer is a novel combination of detector, optical bench and electronics technologies that provides users with a remarkably sensitive system for demanding low-light level applications such as fluorescence, DNA sequencing, astronomy and Raman spectroscopy.  The QE65000 can achieve up to 90% quantum efficiency with high signal-to-noise and rapid signal processing speed.

The Ocean Optics line of high-sensitivity back-thinned 2D FFT-CCD spectrometers for low light-level, UV-sensitive and other scientific applications now includes the uncooled Maya 2000 and Maya 2000-Pro, which offer greater than 90% quantum efficiency, high dynamic range and excellent deep-UV response (<190 nm).

The USB2000+ Miniature Fiber Optic Spectrometer is a unique combination of technologies 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. This innovative combination produces our fastest spectrometer yet and provides resolution to 0.35 nm (FWHM). The USB2000+ allows users to capture and store a full spectrum into memory every millisecond (that's 1,000 full spectra every second) when the spectrometer is interfaced to a computer via a USB 2.0 port. The USB2000+ is perfect for chemical, biochemical and other applications where fast reactions need to be monitored.
