OEM and end user versions available
UV, Visible and NIR versions and custom configured ranges
TE cooled high stability and low dark counts
Built-in 16 bit digitizer and PC interface
0.3 to 20 nm resolution versions available
Plug-and-play high speed USB 1.1/2.0 interface
Up to over 180 complete spectra/s transferring speed

BTC112E Series products are low cost and high performance TE cooled linear CCD spectrometers. They are equipped with 2048 elements thermoelectric cooled (TEC) linear CCD arrays, built-in 16 bit digitizers with high speed USB 1.1/2.0 interfaces and optimized high throughput spectrographs.

Compared with non-cooled CCD spectrometers the BTC112E Series products offer higher dynamic range, greatly reduced dark counts and superior long term operation stability, thus are ideal for low light level detections and long term monitoring applications. They are also equipped with an unique integration time multiplier function which supports for 17 minutes or longer integration period to take the advantage of low dark counts in light starving applications.

The series come in standard wavelength ranges of UV, Vis, NIR or custom specified. Resolution of 0.3 - 20 nm may be supplied depending on system configurations. Flexible custom configurations and custom application support are provided.

Applications

UV, Vis and NIR spectroscopy
Raman and fluorescence spectroscopy
OEM building blocks
Color measurement and monitoring
On-line optical inspection and monitoring
