Key Product Highlights

Up to 1000:1 SNR - NOVA cooled optical fiber spectrometer uses Hamamatu 

Thermoelectric cooled detector with good electronic design quality. This can 

cause the operating temperature to be reduced to 40 ℃ below the environmen-t, suppressing the dark current noise and improve the signal to noise ratio;

Up to 95% peak quantum efficiency - NOVA cooled detector fiber spectrome-er uses a special back thinning technique where light is introduced from the 

rear surface to section PN, which can improve the quantum conversion efficie-ncy, especially the quantum conversion efficiency in the ultraviolet band;

Desin considerations - In addition, the NOVA cooled optical fiber spectromet-er has undergone complex engineering design, integrating the advantages of 

spectroscopy, electronics, structural design, and other aspects which results in the product being hardy.

Application Highlights:

Fluorescence/ Raman Spectroscopy - Fluorescence intensity is usually 

one order of magnitude weaker than the excitation light, which is a weak light signal. To detect the fluorescence spectrum, a high-sensitivity fiber spectrom-eter is generally required as compared to the Raman signal, which is strong-er. The cooled optical fiber spectrometer is also required to have the ability 

for long-term exposure.

Absorption Spectrum - The difference between the intensity of the absorpti-on spectrum to be measured and the reference light can reach 3 orders of 

magnitude, which requires a fiber optic spectrometer with a signal-to-noise 

ratio of more than 1000:1.

Microscopic Spectroscopy - The collection of spectral signals in the micro-n-scale region is needed, which requires the optical fiber spectrometer to 

have the ability to detect weak light signals.

Angular-Resolved Spectroscopy - In an angular-resolved spectroscopy 

system, the optical signal is decomposed into various angles and is collected one by one. This requires the spectrometer to have the ability of low-light 

detection and high-speed collection.
