New UV enhancing coating



Spectral Products is offering the new ethernet communication SM445N Toshiba TCD1304 spectrometer. Thanks to the enhanced design on the electronic board of the SM445N, the dark current noise level as well as the data acquisition speed have been improved. 

Based on a special optical bench design, it supports various applications where spectral or color measurements are required, including high-speed data acquisition. The SM445N can accept light directly through its built-in slit or via optical fiber. The durable mechanical housing that encloses the SM445N provides stable optical bench operation over a wide range of temperatures.

Our array detector (in conjunction with our special UV coating process and customized order sorting filters) allows up to a 1050 nm measurement range from 200 nm to 1050 nm (a smaller measurement range mix increases spectral resolution and light sensitivity). 

SM445N delivers acquisition communications via USB and  Ethernet. Our USB board can support up to 8 multi-channel configurations, which allows a wide range of high-resolution or dual spectrometer systems (one for measurement and the other for reference). Applying a new UV-enhanced coating to the CCD increases UV sensitivity below 450 nm compared to conventional UV coatings widely used in CCD spectrometers. Thanks to this new UV coating, signal sensitivities below 450 nm can generally be improved up to ~2-3 times more.

Software support includes SDKs and DLLs for developing dedicated applications and Windows OS-based spectrum acquisition and analysis software (SMProMX).
