Photonic Sense

IV IR OPTICS GmbH is a wholly owned subsidiary consolidated into the group accounts of Hellma Holding GmbH. It does not publish separate revenue, profit, balance-sheet or cash-flow figures. Its predecessor's figures were never broken out in Jenoptik's segment reporting. The only stand-alone figure in the public domain is FY2020 revenue, given by Jenoptik when it announced the sale.

The following are not publicly disclosed for FY2021–FY2025: gross profit, operating income, EBITDA, pre-tax and net income, EPS, dividends, margins, total assets, cash, debt, equity, goodwill and intangibles, working capital, operating cash flow, capex, free cash flow, ROE, ROA, ROIC, liquidity and leverage ratios, interest coverage, asset turnover and cash conversion cycle. As a GmbH with no listed securities, the company pays no public dividends and has no share buybacks. Its funding comes from the Hellma Materials sub-group.

Commentary on trends and drivers. Four points follow from the disclosures that do exist.

First, scale was modest and shrinking under Jenoptik. The predecessor bought more than 10 tonnes of germanium a year around 2008 but only "several tons" a year by 2018. This reflects a shift in European infrared demand and the loss of lower-end thermography volume to Chinese suppliers. FY2020 revenue of about EUR 6 million was earned in a year Hellma Holding's management report calls very weak because of the pandemic.

Second, the 2021 transfer was an asset deal. Hellma Holding's 2021 group report says the sharp rise in group assets and inventories came mostly from widening the consolidation scope. The new subsidiary took over Photonic Sense's fixed assets and selected inventories, while Photonic Sense's legal liabilities stayed with the seller's entity, now Hörsel GmbH. Consolidating the Eisenach germanium business in the second half of 2021, together with strong fourth-quarter sales, lifted group receivables at year end.

Third, from 2023 germanium metal prices dominate reported revenue. European 99.999% germanium averaged USD 1,289–1,400/kg in June 2023 (Fastmarkets, Rotterdam). It rose to USD 3,150/kg in January 2025 and USD 5,380/kg in October 2025 (USGS), and reached USD 10,000–12,750/kg in July 2026 (Fastmarkets). Germanium makes up most of the cost of a germanium blank, so IV IR Optics' nominal revenue in 2024–2026 has almost certainly grown well beyond EUR 6 million, even if volume in kilograms was flat. Whether margins grew too depends on pass-through clauses and on how much inventory was bought before prices rose. Neither is publicly disclosed.

Fourth, working capital intensity has risen sharply. A germanium crystal grower must hold metal stock, crystals in process and finished blanks. With feedstock eight to nine times more expensive than in mid-2023, the cash tied up per tonne of inventory has multiplied. This is the main financial pressure point for a small subsidiary and makes the parent's financial backing important.

The June 2023 and July 2026 values are midpoints of Fastmarkets Rotterdam monthly averages. The January and October 2025 values are USGS European price points.

Management guidance. No guidance is published by IV IR Optics or Hellma. Peer signals are positive for germanium processors that have secured feedstock. Umicore expects continued momentum in Specialty Materials on germanium demand. 5N Plus is expanding refining. European prices stood at record levels in mid-2026.

Bull case.

1. Strategic scarcity. IV IR Optics is one of very few non-Chinese, EU-based germanium crystal growers, with defence and FLIR qualification history. Chinese licensing and blacklisting of Western defence primes push demand toward exactly this kind of source. That should support volumes and pricing power.

2. Price leverage. Germanium cost is the main element of blank value. If pass-through works, revenue in 2024–2026 should be a multiple of the EUR 6 million FY2020 base, and longer-term contracts reduce volatility.

3. Group bundling. Hellma can offer germanium alongside ZnS, ZnSe, Cleartran® and fluoride crystals from Jena, Sweden and Louisiana. Few competitors other than Umicore and Coherent can offer a multispectral material set.

Bear case.

1. Feedstock squeeze. Without its own refining, the company competes for scarce metal against Umicore, which has secured processed germanium through its STL partnership. At USD 10,000–12,750/kg, inventory financing strains a 25-person subsidiary.

2. Substitution. Germanium-free chalcogenide lenses are spreading quickly in volume cameras, as LightPath's redesigns show, and this erodes the commercial thermography base.

3. Scale and concentration. A single plant, a sole managing director who also runs the parent, and pre-2021 volume decline (from more than 10 t to several tonnes a year) limit resilience.

Analyst verdict. Photonic Sense has become IV IR Optics, a small asset whose strategic value has grown sharply. For 16 years under Jenoptik it was a captive feeder of germanium blanks. Its volumes shrank as commercial thermography moved to Asia, and Jenoptik sold it in 2021 for an undisclosed sum as a non-core upstream activity worth about EUR 6 million in revenue. Hellma Materials bought it at close to the bottom of the germanium cycle, about two years before China turned germanium into a tool of trade policy. Since mid-2023 European germanium prices have risen about eight-fold. Western defence buyers face Chinese blacklisting, and AI-driven fibre demand competes for the same metal. In this market, qualified non-Chinese crystal capacity in the EU is scarce. The company's large-diameter Czochralski capability, its long-standing qualification with the world's leading thermal-camera maker, and its ISO-certified crystal-to-blank process make it hard to replace for European and allied optics makers.

The investment case is about how well the business converts this scarcity into earnings, and the evidence is limited. The company does not refine germanium. It must finance inventory at record prices, and it competes for feedstock with Umicore, a much larger integrated rival that has already secured processed germanium. Volume commercial optics are moving to germanium-free chalcogenide glass. One plant and one managing director carry concentration risk. No stand-alone financials are published, so profitability cannot be assessed directly.

On balance, IV IR Optics is a strategically valuable but financially opaque niche asset. Its outlook is positive in defence-grade, large-aperture germanium and structurally challenged in commodity thermography. Its fortunes over the next year depend mostly on two outside factors: Chinese export policy after November 2026, and how fast Western germanium feedstock becomes available. Hellma's ownership is the main mitigant, giving the business balance-sheet support, cross-selling and a multi-material IR portfolio that a stand-alone company of its size would lack.
