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.

Executive Whitepaper: Industrial & Analytical Dynamics of the Greater Chicago Market

The Greater Chicago metropolitan area—spanning Cook, DuPage, and Lake counties—serves as one of North America’s most complex and vital hubs for life science discovery, advanced manufacturing, and water safety testing. As institutions such as the University of Chicago, Northwestern University, Argonne National Laboratory, and Fermilab push boundaries in synchrotron light sources and biophotonics, the demand for dimensionally stable optical channels has transitioned from commodity glassware to precision micro-engineered quartz solutions.

Chicagoland Biopharma Corridor

Lake County’s world-class pharmaceutical manufacturing corridor demands flow cells capable of sub-nanoliter volume control for in-line chromatography, protein crystallization monitoring, and automated high-throughput drug screening.

Petrochemical & Refinery Controls

Operating along the Calumet River and Northwest Indiana industrial zones, petrochemical downstream operations utilize UV/NIR absorption quartz flow cells to monitor hydrocarbon fractions in real-time under aggressive pressure gradients.

Great Lakes Environmental Testing

Continuous monitoring of Lake Michigan’s freshwater ecosystems relies on deep-UV transparent fused silica cuvettes for trace detection of heavy metals, per- and polyfluoroalkyl substances (PFAS), and organic contaminants down to parts-per-trillion levels.

Shifting Global Procurement Architectures

Tier-1 original equipment manufacturers (OEMs) across North America, Europe, and Asia-Pacific are transitioning away from traditionally cemented optical cells toward monolithic thermal fusion (fire-fused) and molecular optical contact bonding. Adhesive-bonded cells consistently fail under aggressive solvents—such as tetrahydrofuran (THF), chloroform, and concentrated acids—causing phase separation, beam deflection, and baseline drift.

Procurement teams now prioritize supply contracts with direct manufacturers capable of providing end-to-end spectral verification, interferometric surface topography readouts, and documented hydroxyl (OH) concentration levels to suppress parasitic fluorescence in sensitive bio-assays.

Next-Gen Flow Cell Design Trends

The continuous miniaturization of sample volumes has stimulated significant innovation in microfluidic fused silica channels. Micro-bore flow cells featuring optical apertures as small as 0.5 mm require precision CNC ultra-sonic core-drilling without propagating micro-fractures along internal optical surfaces.

Modern continuous process analytical technologies (PAT) also require flow cells integrated with specialized PEEK, 316L stainless steel, or titanium compression assemblies, allowing automated spectrophotometers to operate reliably under pulsing hydraulic pressures up to 100 bar without optical window displacement.

Frequently Asked Technical Questions: Quartz Cuvettes & Flow Cells

Essential technical, material, and optical engineering answers for Chicago laboratory procurement officers and precision instrument designers.

What is the definitive advantage of fused quartz flow cells over optical glass (BK7) in spectrophotometric applications? +

Synthetic fused silica (JGS1) maintains exceptional transmittance (>85% without coating) down to 190 nm in the deep ultraviolet spectrum, whereas optical glasses like BK7 exhibit a sharp transmission cut-off around 340 nm. Furthermore, quartz exhibits an ultra-low coefficient of thermal expansion (5.5 × 10⁻⁷ /°C), ensuring zero dimensional drift and pathlength variability during exothermic chemical analyses or variable temperature spectroscopy in Chicago analytical facilities.

How do you construct optical flow cells to prevent solvent leakage under high operational pressure? +

Our flow cells are manufactured using high-temperature molecular fire fusion or optical contact bonding rather than organic adhesives or epoxies. By fusing the quartz interface at temperatures exceeding 1,200 °C, the cell forms a singular, monolithic silica body that eliminates joint deterioration caused by harsh solvents (such as DMSO, dichloromethane, or acetonitrile) and withstands hydraulic pulse pressures exceeding 30 to 80 bar depending on channel geometry.

What tolerances do you maintain on custom cuvette path lengths? +

For standard 10 mm path lengths, we hold an ultra-tight standard tolerance of ±0.01 mm (10 µm). For micro-path length cuvettes (0.1 mm to 1 mm) frequently specified by Illinois bio-instrumentation developers, we maintain tolerances within ±0.005 mm, verified via digital laser micrometer and interferometric pathlength characterization.

How does your facility package precision quartz glassware to prevent shipping damage to the US Midwest? +

Every optical component undergoes ultrasonic cleanroom degreasing, lint-free static-dissipative vacuum packing, multi-layer cushioning in individual high-density foam suspension cases, and crating in reinforced export wooden cases. We guarantee zero breakage upon arrival at Chicago facility loading docks.
