Which glass and crystal materials can BY Photonics machine?

We machine JGS1 UV fused silica, JGS2 and JGS3 fused quartz, borosilicate glass, optical glass, optical color filter glass, infrared glass, samarium- and cerium-doped glass, sapphire, PTFE-based diffuse reflector material and laser ceramics.

What is the difference between JGS1, JGS2 and JGS3 quartz glass?

JGS1 is synthetic UV-grade fused silica with high transmission from about 185 nm. JGS2 is fused quartz for the visible range with good UV transmission from about 220 nm. JGS3 is infrared-grade fused quartz with low OH content that transmits up to about 3,500 nm.

Which drawing formats should I send for a custom part?

STEP, IGES, DWG, DXF or a dimensioned PDF are all accepted. Please include material, quantity, critical tolerances, surface quality, coating and the operating environment of the part.

How quickly will I receive engineering feedback?

Our engineers review complete drawings and return a manufacturability assessment within 24 hours on working days.

Do you support prototypes and export shipping?

Yes. We support prototype and low-volume orders as well as repeat batch production, and our components are shipped to customers worldwide.

Paris-Saclay Deep-Tech & Quantum Cluster

The academic and industrial concentration at Paris-Saclay requires customized borosilicate capillary tubing for atomic vapor cells, quantum sensing housings, and optical traps. The low thermal expansion and high optical homogeneity minimize wavefront distortion in ultra-stable cryogenic and vacuum interfaces.

Genopole & MedTech Diagnostic Microfluidics

Leading biopharmaceutical researchers in Evry and Paris center utilize borosilicate capillary tubing for capillary electrophoresis (CE), micro-chromatography columns, and in-vitro diagnostic (IVD) chips. Inert hydrolytic Class 1 resistance eliminates leaching into sensitive biological assays.

Aeronautic & Defense Thermal Sensing

Operating near Le Bourget and the larger Île-de-France defense corridor, sensor manufacturers embed our precision borosilicate rods and heavy-wall capillary sleeves into pitot-static systems, high-voltage insulation cores, and fiber-optic gyroscopes (FOG) demanding extreme shock survival.

Compliance, Quality Assurance & French Trade Protocols

Ensuring frictionless procurement, full CE marking compliance, and traceable material documentation across France.

EU REACH & RoHS Validation

Every shipment of borosilicate capillaries and solid rods delivered to Charles de Gaulle (CDG) and Paris logistics hubs includes batch-specific REACH declaration certificates and RoHS analytical compliance reports, eliminating heavy-metal contaminants.

Metrology & Cleanroom Packaging

Capillaries undergo 100% optical laser gauging for ID/OD concentricity. Parts are ultrasonic cleanroom washed, flame-sealed on demand to prevent inner bore contamination, and vacuum sealed inside antistatic, double-blister enclosures.

DDP Express Logistics to Île-de-France

We provide full DDP (Delivered Duty Paid) shipping service via air express directly to Paris research sites, Saclay laboratories, and production lines in the surrounding industrial parks, handling all customs clearance and VAT filing.

Frequently Asked Questions: Sourcing Capillaries for Paris Clients

In-depth responses regarding manufacturing capabilities, tolerances, lead times, and custom engineering.

What geometric configurations are available for borosilicate capillary tubing?

We manufacture single-bore circular, rectangular, square, oval, multi-bore (dual-bore, four-bore, multi-channel arrays), and customized D-shaped borosilicate capillaries. We also fabricate heavy-wall solid rods and capillary sleeves tailored to your exact optical or mechanical drawings.

How do you guarantee bore diameter concentricity and straightness?

Our redrawing towers utilize continuous closed-loop non-contact laser micrometer scanning across both X and Y axes during the thermal pull. This ensures inner diameter (ID) tolerances up to ±0.002 mm, outer diameter (OD) tolerances up to ±0.005 mm, and straightness better than 0.1 mm per meter.

Can you supply flame-polished ends or ground and beveled edges?

Yes. Depending on your assembly method in Paris, we offer score-and-snap clean breaks, precision diamond-wheel saw cuts, optical flat polishing (λ/4 flatness, 20-10 scratch-dig), 45-degree micro-beveling, or flame-glazed end faces for crack mitigation.

What is the typical shipping lead time to Paris facilities?

Standard prototype and sample runs ship within 5 to 10 business days. Production batch volumes are fulfilled within 2 to 3 weeks, with priority direct air freight to Paris (CDG / Orly) taking 3 to 5 business days for door-to-door delivery.
