BulletNEW!!! CONCAVUS® High Resolution Spectrometer Series

Download the PDF

CONCAVUS® Fiber Optic Spectrometers use a novel optical design which is different from the conventional planar Czerny-Turner and flat field grating design(FFG).  FFG design uses fewer optical components than planar Czerny-Turner for better thermal and mechanical stability, but it still suffers in spectral & spatial resolution and large numerical aperture (NA). CONCAVUS® spectrometers are based on Xiang System, which are comprised of an aberration corrected concave grating and transmissive aberration correctors.  It dramatically reduces the residual aberration in FFG designs and increases the spectral and spatial resolution even with a large NA.  Along with the solid opto-mechanical design, CONCAVUS® series spectrometers enable  customers to achieve higher performance in their applications.

  • Minimized optical aberration for high finesse spectral images; Low distortion.
  • Higher spectral and spatial resolution than conventional systems at high numerical aperture;
  • Excellent spectral images at NA=0.22 or higher, even at NA=0.6;
  • Fewer components and excellent thermal and mechanical stability;
  • Original holographic grating for lower stray light;
  • Higher linearity of spectral dispersion on detector for easier calibration.

 

optics

Standard SMA connectors are used in CONCAVUS® systems. Custom input connector are possible. 


The CONCAVUS® series comes with a 16 bit AD converter, and USB2.0 high speed interface. It is especially designed for high resolution measurements. Its integration time can be adjusted from 10us to seconds to cover a wide range of light input power.


The CONCAVUS® is equipped with terminal blocks Digital IO ports. These ports can be easily connected to other units for external triggering, shutter control, pulsed light sources, and GPIO controls and so on.

.  

The CONCAVUS® series runs on USB power and comes with SPEC_SOFT GUI software for Windows, a complete manual and USB interface cable. Multiple CONCAVUS USB spectrometers can be connected to a PC for simultaneous control.
