SOL 2.6 近紅外線高性能光譜儀(含電子制冷器)

1500-2550nm* NIR TE Cooled InGaAs Array Spectrometer

The Sol™ 2.6 is a high performance linear InGaAs array spectrometer, featuring 256 pixels and providing high throughput and large dynamic range with TE Cooling down to -15˚C via a built-in 3-stage cooler.

EEach spectrometer features an SMA 905 fi optic input, built-in 16-bit digitizer, and is USB 2.0 plug-and-play compatible. The built-in autozero function automatically reduces dark current and dark non-uniformity, resulting in an increased signal-to-noise ratio.

 Software control allows the user to choose from four types of operation modes: Maximum Dynamic, High Dynamic, High Sensitivity, and Maximum Sensitivity. Customized spectral resolution and application support are also available.

Technical   Details

Fiber   Coupler

     Secures Fiber to Ensure Repeatable Results

By coupling a fiber optic to the SMA 905 adaptor, light will be guided to the slit and optically matched, ensuring reproducibility.  For free space sampling, a diffuser or lens assembly can be connected directly to the SMA 905 adaptor.

 

Entrance  Slit

 
Determines Photon Flux and Spectral Resolution

Light entering into a spectrometer’s optical bench is vignetted by a pre-mounted and aligned slit.  This ultimately determines the spectral resolution and throughput of the spectrometer after grating selection. We offer a variety of slit widths to match your specific application needs: from 10µm - 200µm wide, with custom slits available.

Collimating Mirror

   Collimates and Redirects Light Towards Grating

Both mirrors are f/# matched focusing mirrors coated with a special coating, which enhances the NIR sigral.

 
Diffraction Grating

  
Diffracts Light, Separating Spectral Components

The groove frequency of the grating determines two key aspects of the spectrometer’s performance: the wavelength coverage and the spectral resolution.  When the groove frequency is increased, the instrument will achieve higher resolution, but the wavelength coverage will decrease. Inversely, decreasing the groove frequency increases wavelength coverage at the cost of spectral resolution.

The blaze angle or blaze wavelength of the grating is also a key parameter in optimizing the spectrometer’s performance. The blaze angle determines the maximum efficiency that the grating will have in a specific wavelength region.

Thermoelectric Cooler

    Reduces Dark Noise and Increases Detection Limits

Cooling an array detector with a built-in thermoelectric cooler (TEC) is an effective way to reduce dark current and noise, as well as to enhance the dynamic range and detection limit.

When the InGaAs array detector is cooled from a room temperature of 25˚C down to -15˚C by the TEC, the dark current is reduced by ~32 times and the dark noise is reduced by ~5.7 times. This allows the spectrometer to operate at longer exposure times and to detect weaker optical signals.
