Ocean Optics Spectrometer with Spectral Hyper Adapter
Spectral has developed the "Spectral Hyper Adapter" that can extend the spectral resolution of conventional grating spectrometers by a factor of ten. The increased resolution is provided with a single adapter unit that is designed to operate with the Ocean Optics line of compact spectrometers. The optical input of the high-resolution unit uses a 50-micron multimode fibre optic cable. The output of the unit is then fed directly to the Ocean Optics spectrometer through another multimode fibre cable where the high-resolution spectrum is obtained. [See diagram below].
The spectral resolution of a conventional grating spectrometer is limited in a compact design. The addition of our Hyper Adapter provides superior resolution in a small package. The unit can be configured to work with a range of spectrometers. A resolution of 0.005 nm can be achieved when used with a spectrometer of 70-nm spectral range. Larger spectral ranges can be used while still maintaining the same range to resolution ratio.
Wavelength range to resolution: Ocean Optics spectrometer range to resolution ratio of about 1,500:1 is extended to 15,000:1. For example, a spectrometer that covers the 450 nm range from 400 to 850 nm would normally have a maximum resolution of 0.3 nm could be reduced to 0.03 nm with the Spectral Hyper Adapter.
Wavelength resolution: 5 pm at 840 nm, for example
Wavelength range: 75 nm centered at 840 nm, for example
Wavelength accuracy: About 10-pm relative to Ocean Optics accuracy
Optical throughput: 50%
Measurement time: 1-2 seconds
Dimensions: 1¼ x 1½ x 5 inches. Separate unit from Ocean Optics spectrometer, without calibration source.
