Choosing a USB spectrometer means balancing upfront cost against what you get in the box. The four options here range from a new compact mini instrument at USD 199.00 to a used Ocean Optics USB2000 listed at USD 450.00, with two used units in between. If you need UV-range work, a ready-to-run instrument, or a project-based build, the decision comes down to how much setup you want to handle yourself.
Quick Take
The only new unit is the ThunderOptics Mini USB Spectrometer at USD 199.00, which also has the lowest listed price. The tested Ocean Optics USB2000+ listing, at USD 418.00, is the one with a stated UV range of 340-1034nm. The other Ocean Optics unit is listed in excellent condition at USD 450.00, with its details centered on brand, condition, model, and type. The B&W TEK Optical Spectrometer, at USD 199.99, is sold as Raman spectrometer parts and framed as a learning project, so it is not a plug-and-play option.

Decision Matrix
- Ready-to-run used instrument with a stated UV range: Choose the Ocean Optics USB2000+ listing at USD 418.00 if you want a tested unit with calibration wording and a specified 340-1034nm range.
- New instrument at a lower price: Choose the ThunderOptics Mini USB Spectrometer at USD 199.00 if you want a new unit with a compact physical format and a 350nm to 850nm range described in the listing.
- Used Ocean Optics with a strong condition claim: Choose the Ocean Optics USB2000 at USD 450.00 if the excellent-condition wording matters more to you than the extra listed cost.
- Parts or project work: Choose the B&W TEK Optical Spectrometer at USD 199.99 if you enjoy building out the power and serial connections yourself.
Product Notes
Ocean Optics USB2000 USB Spectrometer, excellent condition - USD 450.00
This is the highest listed price in the group. The title leads with excellent condition, and the description adds that it was used only a handful of times. That makes it a strong candidate if you want a familiar Ocean Optics USB2000 without the extra setup notes found in the parts listing. The listing's details focus on brand, condition, model, and type. If you need a confirmed UV or visible range, the other Ocean Optics listing spells out 340-1034nm. Pick this one when the condition wording and the Ocean Optics nameplate are enough for your application.
1PC Ocean Optics USB2000 USB2000+ Spectrometer uv range 340-1034nm (Tested) - USD 418.00
The listing calls this a tested unit and says the wavelength is recalibrated before shipment. It also names a UV range of 340-1034nm and includes a Sony ILX511B 2048-pixel CCD in the configuration notes. At USD 418.00, it is USD 32.00 below the excellent-condition Ocean Optics listing. The description says the condition is almost brand new and that the software is free after ordering. The limitation is that it is still a used item, and the condition is described by the seller rather than by a standard grade. If you want a stated wavelength range and a tested label, this is the practical Ocean Optics pick.
Mini USB Spectrometer Spectromètre Spektrometre - ThunderOptics - New Product - USD 199.00
This is the only new unit in the batch, and it is the least expensive at USD 199.00. The description identifies it as a mini photo-spectrometer with a wavelength range from 350nm to more than 850nm and says the optics have been upgraded. The unit is black, made of aluminium, and has a Country of Origin of France. It appears aimed at hobby, educational, and research settings. The trade-off is that it is compact and general-purpose rather than a specialized Raman unit or a used lab spectrometer. If you want a new instrument with a lower listed price and do not need a UV-range specification, this is the one to consider.
B&W TEK Optical Spectrometer - RAMAN SPECTROMETER PARTS - GREAT LEARNING PROJECT - USD 199.99
This listing is straightforward about what it is not: it is sold as Raman spectrometer parts and described as a great learning project. The description says these units were originally installed in medical devices and used for Raman spectroscopy, but the seller recommends them for general non-Raman spectroscopy. It is described as sealed. You will need to supply a 5-volt AC adapter and a serial-to-USB adapter, so account for extra parts and setup time. At USD 199.99, it is close to the ThunderOptics price but carries a completely different amount of work. Choose it if you want a project rather than a ready-to-run instrument.
Final Recommendation by Use Case
For a used instrument with a stated UV range and a tested label, the Ocean Optics USB2000+ at USD 418.00 is the clearer choice in the group. For a new, low-priced instrument, the ThunderOptics Mini at USD 199.00 gives you a clean starting point without used-condition unknowns. For a parts-based learning project, the B&W TEK Optical Spectrometer at USD 199.99 is the right fit. The Ocean Optics USB2000 at USD 450.00 suits a shopper who wants the same platform in a listing that stresses excellent condition over a specific wavelength range.
