Spectra S1 and S2: Major Differences

Spectra S1 and S2 are two popular electric breast pumps used to express milk for infants. While both pumps are portable, comfortable and easy to clean, there are a few key differences between the two models.

The Spectra S1 is a single-phase pump, meaning it only has one mode of suction. It is lightweight, making it easy to carry around and transport. The Spectra S1 also has a built-in rechargeable battery and a nightlight, both of which make it convenient for nighttime pumping and travel.

The Spectra S2, on the other hand, is a double-phase pump. This means that it has two phases of suction: stimulation and expression. The stimulation phase is designed to imitate a baby’s natural suckling pattern and is used to help initiate a let-down. The expression phase is designed to help increase milk production and is typically used for longer pumping sessions. The Spectra S2 also comes with a digital display and adjustable suction levels, allowing the user to customize their pumping experience.

When it comes to noise levels, the Spectra S1 is generally quieter than the Spectra S2. Additionally, the S1 has a built-in nightlight, which is great for nighttime pumping and travel. The S2 does not have a nightlight but instead has a digital display, which allows the user to adjust the suction levels.

The Spectra S1 and S2 have different price points. The S1 is typically the cheaper of the two models and is usually the most affordable option for those on a budget. The S2, on the other hand, is typically more expensive and is the better choice if you’re looking for a more customized pumping experience.

Overall, the Spectra S1 and S2 are both great electric breast pumps. While the S1 is typically the more affordable option, the S2 offers more features, such as adjustable suction levels and a digital display. Both pumps are portable, comfortable and easy to clean, making them great options for busy moms.

Spectral Range

The most significant difference between the Spectra S1 and S2 models is their spectral range. The Spectra S1 model has a wavelength coverage from 0.4 to 2.5µm. This range allows for a variety of applications, such as astronomical observations and spectroscopy. On the other hand, the Spectra S2 model has a wavelength coverage from 0.35 to 5.0µm. This extended range allows for even more applications, such as infrared imaging and remote sensing.

Design

The Spectra S1 and S2 models also differ in their design. The Spectra S1 model is a single-element slit spectrograph that operates with a fixed grating and a motorized slit. It is designed to produce diffraction limited spectra with high resolution and low noise over a wide range of wavelengths. The Spectra S2 model is a double-element slit spectrograph that operates with a motorized grating and a motorized slit. It is designed to produce high-resolution spectra over a larger wavelength range.

Price

The last major difference between the Spectra S1 and S2 models is the price. The Spectra S1 model is generally more affordable than the Spectra S2 model. This is mainly due to the fact that the Spectra S1 model operates with a fixed grating, which requires fewer components and is thus cheaper to manufacture. The Spectra S2 model, on the other hand, requires more components, so it is usually more expensive.
