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 -10˚C by the TEC, the dark current is reduced by 12.25 times and the dark noise is reduced by 3.5 times. This allows the spectrometer to operate at longer exposure times and to detect weaker optical signals.
