Physics & Astronomy
From Galileo and Newton to Sagan and Hawking, great thinkers have studied light to explore how the universe works. Today, Ocean Optics collaborates with scientists and researchers as they use our spectrometers and accessories to measure, move and apply light, helping to unlock mysteries, expand knowledge and take on challenges facing our world and beyond.

High Resolution Spectrometers
Resolution customizable down to 0.05 nm for applications from atomic spectroscopy to laser characterization
Example Setup: HR4000 Spectrometer
Overview
The HR4000 High-resolution Spectrometer is ideal for measuring the spectral characteristics and intensity of continuous-wave and pulsed lasers. For high-power lasers, an integrating sphere or cosine corrector attenuates the light to avoid saturating the CCD detector array. OceanView software captures peak parameters and other spectral information.
Spectrometer
The HR4000 Spectrometer uses our “HR” Optical Bench, which is designed to yield high optical resolution in a compact optical bench, making it suitable for resolving fine spectral features.
For laser characterization, we recommend a grating with a high groove density. A good option is the H6 1200 mm-1 grating set to a 750-925 nm wavelength range, complemented in the optical bench with a 5 µm slit as the entrance aperture. This configuration provides ~0.12 nm resolution (FWHM). For better resolution consider an 1800 mm-1 or 2400 mm-1 grating.
Additional spectrometer options for high-resolution measurements include the HR2000+, which has slightly faster integration time than the HR4000; and the STS microspectrometer, a very small-footprint but highly reproducible unit that is excellent for large-volume customization projects.
Sampling Optics
There are several possible sampling setups for your laser measurement: a CC-3-UV cosine corrector with an optical fiber; the FOIS-1 integrating sphere with a fiber; or fiber assembly coupled to the laser. Optical posts hold the optical fixtures in place.
