99.99% SiO₂ ROHS-certified ultra-thin fused silica substrates polished for protective optoelectronic viewports and laser cavities.
Precision slotting and laser glass-welding services delivering 99.98% silica boats for cleanroom annealing and wet etching baths.
Heavy-duty heat radiation tubes engineered for disinfection assemblies, lab drying cabinets, and high-purity fluid dispensers.
Custom-machined reactor vessel featuring flawless optical interfaces, extreme internal pressure resilience, and neutral chemical stability.
ROHS-certified optical grade flats designed for beam-splitters, laser windows, and deep-UV spectroscopy across 200–2500nm wavelengths.
Insulated precision instrument windows offering dimensional repeatability and chemical inertia for harsh industrial environments.
From the Canton of Bern's micro-machining valleys to the laser and medical instrument research clusters across Biel/Bienne and the Swiss Plateau, engineering teams require quartz plates manufactured without micro-fissures or residual striae.
The Bernese Jura region houses world-leading horological manufacturing. Precision quartz plates serve as zero-CTE reference flats, calibration optical stages, and high-frequency sensor windows where linear expansion must stay below 5.5 × 10⁻⁷ /°C.
Our JGS1 synthetic silica flats eliminate thermal drift during laser micromachining and high-vacuum sputtering of mechanical gear trains.
Bern's medtech enterprises specialize in surgical lasers, flow analysis, and optical diagnostics. UV-transparent quartz plates fabricated under JGS1/JGS2 standards offer superior internal transmission from 185 nm to 2500 nm.
Components support sterilization autoclaving, excimer laser apertures, and bio-compatible spectrophotometry microplates without fluorescent interference.
Collaboration with institutes such as the University of Bern demands high chemical purity. Our 99.99% SiO₂ wafers, boats, and flange plates resist plasma sputtering, halogen etch gases, and thermal gradients up to 1300°C.
Trace metal analysis certifies aluminum, copper, and iron contamination below stringent PPM levels.

By integrating raw silica extraction, refinement, and automated multi-axis CNC finishing within a single 14,271 m² operational facility, we eliminate intermediate handling markups while providing certified traceability.
Micro-strains in quartz can trigger catastrophic structural failure under vacuum or high thermal shocks. Lovri Quartz subjects 100% of finished plates to polariscopic stress evaluations before packaging.
We work directly with engineering documentation in DWG, DXF, and STEP formats to deliver drop-in quartz replacements and custom prototyping for Bern-based original equipment manufacturers.

As Swiss manufacturers face inflationary pressures and supply chain diversification imperatives, direct-from-source quartz imports provide a clear operational hedge without compromising technical standards.
Swiss environmental and chemical ordinances (ChemO) mirror the strictest EU norms. Lovri Quartz supplies third-party SGS RoHS certification sheets, CE-mark compliances, and full material test certificates (MTC) proving non-detectable heavy metal migration for analytical and medical devices.
With expedited air courier options into Bern Airport (BRN) and Zurich Airport (ZRH), standard delivery times for customized optical plates span 5 to 8 business days post-fabrication. Consolidated packaging ensures zero breakages via custom foam-formed slots and multi-layered impact wooden crates.
Clear, direct answers regarding customs, optical verification, minimum order quantities, and technical tolerances.
Yes. We regularly fabricate according to ISO 2768-mK or customer-specific drawings requiring dimensional tolerances to ±0.02 mm, parallelism < 20 arcseconds, and surface scratch-dig ratings of 40/20 or 20/10 for optical laser interfaces.
Plates are individually ultrasonic cleaned, coated with peelable static protection film, vacuum-sealed in cleanroom polyethylene bags, and suspended inside high-density shock-absorbing EPE foam surrounded by reinforced plywood crates.
Standard prototypes (1–5 pieces) take 4 to 7 working days for machining, grinding, and stress inspection. Volume orders typically ship within 12 to 18 days via direct DHL, FedEx, or Air Cargo with customs declaration documents provided.
Yes. Upon request, each production batch can be supplied with certified UV-Vis-NIR spectral transmission curves validating transmission percentages across wavelengths from 190 nm through 3000 nm.
