ZEISS OPMI LUMERA 700 Ophthalmic Surgical Microscope — Auction Analysis
A photo-confirmed ZEISS OPMI LUMERA 700, serial 6634144530, has seller-reported basic operation and meaningful exact-model market support, but unconfirmed premium options, advanced function, freight, and service exposure require a conservative $7,300 hammer ceiling before any unknown premium.

Status: Approved · Reviewed September 27, 2026
Completed source-first review approved the BUY and ceiling after checking all eight required areas.
How independent review worksCorrection · September 27, 2026
Affected field: Market-evidence disclosure and comparable records
Original: Aggregate-only disclosure with one synthetic related-model asking/context count and no public comparable records.
Corrected: Record-level disclosure of four exact-model records: two realized signals, one dealer ask retained as context, and one refurbished dealer ask excluded.
The publication adapter discarded the approved retained records and replaced them with a synthetic aggregate representation.
Valuation unchanged · Maximum hammer unchanged · Decision unchanged
- GovAuctions.app: Approved exact-model government-auction sold record.
- Hilditch Group: Approved exact-model auction hammer context.
Correction · September 27, 2026
Affected field: Modeled result at recorded bid
Original: Canonical modeled-result fields were null and the page displayed No bid recorded.
Corrected: USD 10,225 modeled profit and 9,274 basis points (92.74%) modeled ROI at the USD 2,025 observed bid.
The publication adapter preserved the observed bid but did not populate the derived canonical modeled-result fields.

How evidence is classified
Seller facts, photo-derived observations, manufacturer context, unknowns, and LotCaliper assumptions remain explicitly separated.
Photo Derived
Photo-derived
- Supplied auction photographs support physical observations only, not advanced functional performance.
Not Established
Not established
- Foot control, RESIGHT 700, CALLISTO eye, RESCAN/OCT, exact camera/video chain, service history, and advanced functional state are not established.
Manufacturer Context
Independent context
- Exact-model auction signals are retained separately from dealer asks; the conservative resale remains below the reported $34,000 same-currency result.
Lotcaliper Assumption
LotCaliper assumptions
- USD 25000 conservative resale and USD 7300 maximum hammer before any unknown premium.
- USD 2000 freight, USD 4000 testing/repair, USD 3000 uncertainty, and 15% selling-fee reserves.

Sensitivity and robustness
Survives
The published decision survives the selected downside check under the stated bounded assumptions.
Approved downside-tested case
- Max hammer
- $7,300
- Gross resale model
- $20,000–$25,000
BUY: the $2,025 observed bid is materially below the ROI-bound $7,300 ceiling, with no value assigned to unconfirmed premium options.
Costs and maximum bid
| Transaction / operating cost | Amount | Basis |
|---|---|---|
| Selling Fees | $3,750 | LotCaliper assumption: 15% of modeled gross resale. |
| Shipping | $2,000 | LotCaliper pickup, packing, rigging, and inbound-logistics reserve; not a carrier or GSA quote. |
| Testing Repair Reserve | $4,000 | LotCaliper functional-test and diagnostic reserve. |
| Risk Buffer | $3,000 | Approved reserve for buyer-managed removal, configuration, testing, repair, and resale uncertainty. |

Why these confidence levels were assigned
- Identity rationale
- Exact OPMI LUMERA 700 identity and serial 6634144530; visible floor stand, arm, microscope, binocular assembly, monitor, and cabling.
- Material unknowns: None
- Configuration rationale
- Foot control, RESIGHT 700, CALLISTO eye, RESCAN/OCT, exact camera/video chain, service history, and advanced functional state are not established.
- Material unknowns: Bounded
- Condition rationale
- Seller reports power-on and basic functional verification, but no advanced ophthalmic, optical, motion, illumination, video, OCT, calibration, or service testing is evidenced.
- Material unknowns: Bounded
- Market Support rationale
- Exact-model auction signals are retained separately from dealer asks; the conservative resale remains below the reported $34,000 same-currency result.
- Material unknowns: Bounded
- Costs rationale
- Cost reserves are explicit but buyer-specific and unquoted.
- Material unknowns: Bounded
Market support assesses how well the available evidence supports the resale assumption. Exact third-party marketplace records may be omitted when source-use rights are unclear. Each dimension uses the published methodology rubric; a confidence label measures the strength and boundedness of its evidence, not the likelihood of a profitable outcome.
Risks and unknowns
High · Missing Components
