Detailed
Felix Glass Co., Limited supplies drawing-based fused silica windows, plates, discs, rings, tubes and special-shaped optical parts for UV sources, laser beam delivery, analytical instruments and high-temperature equipment. Material grade, wavelength, angle of incidence, clear aperture, surface quality and inspection method are reviewed before quotation. The values below are planning ranges rather than automatic acceptance limits. Final capability depends on geometry, aperture, edge condition, coating and inspection requirements. Surface quality, flatness, parallelism, wedge, clear aperture and edge treatment can be defined by application. Specify wavelength, source type, fluence or power density, pulse conditions, angle of incidence and transmission target. Dimensional, visual, flatness and coating inspection records can be included when stated in the purchase specification. Use the table as an RFQ checklist. Tighter requirements may affect yield, inspection time, lead time and unit cost. Confirm material, drawing revision, wavelength, environment, quantity and critical characteristics. Select stock and machining allowance based on finished geometry and process risk. Cut, grind, drill and profile the component using a route suited to fused silica. Develop specified surfaces while controlling edge condition, wedge and clear aperture. Apply approved coating when required and inspect agreed dimensional and optical characteristics. Separate polished parts and package them according to handling and cleanliness needs. ISO 9001 quality-system documentation and RoHS or other compliance support may be supplied when applicable to the selected material and process. Certification scope and report format must be confirmed during quotation. Felix Glass Co., Limited supports prototype evaluation and repeat production through drawing review, machining, polishing, optional coating and inspection coordination. Procurement teams should request the exact facility, process and certification evidence needed for supplier qualification. Feasibility feedback can identify missing tolerances, coating inputs and inspection definitions before order placement. Blank preparation, CNC shaping, grinding, polishing, coating and final inspection are planned around the approved specification. Inspection criteria and approved drawing revisions can be carried into repeat production planning. For an engineering quotation, send the drawing, material grade, wavelength band, source type, optical aperture, tolerance priorities, surface quality, flatness, coating target, inspection standard, quantity and delivery schedule. For laser service, include available beam and pulse information so the component and coating can be reviewed for the intended conditions. Related capability pages: Sapphire Hub, Custom Sapphire Window Manufacturer, BK7 Optical Glass Factory Supplier, Laser and UV Product Solutions, and High-Temperature Furnace Components. Provide a controlled drawing, material grade, dimensions, tolerances, surface quality, flatness, coating, wavelength, quantity, inspection needs and requested delivery date. The terms are sometimes used broadly, but synthetic fused silica and naturally sourced fused quartz can differ in purity and spectral behavior. State the required grade or optical band so material can be selected correctly. Suitable grades are commonly evaluated for UV systems, but the decision depends on wavelength, thickness, defects, polish, coating, power or fluence, pulse conditions and service environment. Surface-quality requirements such as 20-10 or 10-5 scratch-dig can be reviewed. The applicable inspection standard, clear aperture and performance requirement should be stated on the drawing. Lambda/4 is a common project target and Lambda/10 may be reviewed for suitable sizes and geometries. Always define the reference wavelength, clear aperture and measurement condition. UV AR, narrowband AR and broadband designs can be evaluated. Provide wavelength range, angle of incidence, polarization, environment and durability requirements. Windows, plates, discs, rings, tubes and drawing-based profiles can be reviewed, including holes, slots, bevels and defined edge conditions. Prototype and batch quantities can be discussed. MOQ depends on material, geometry, tooling, coating and inspection scope and is confirmed with the quotation. Lead time is quoted after material availability, machining complexity, coating schedule, inspection plan and quantity are reviewed. Available documentation may include dimensional and visual inspection records, material certificates, coating data and applicable compliance support. Specify required document names and acceptance criteria before order placement. Share the working wavelength, optical and mechanical drawing, quantity and inspection requirements. The engineering team will identify the inputs needed for a formal quotation.

Why Fused Silica Is Selected for UV and Thermal Systems
Property Typical Engineering Reference Selection Relevance Composition High-purity silicon dioxide; grade dependent Supports optical and thermal stability requirements. Thermal expansion Low compared with common optical glasses Reduces dimensional change during thermal cycling. UV transmission Depends on synthetic or natural grade, thickness and surface condition Material certificates and transmission data should match the working band. Thermal shock behavior Suitable for many rapid-temperature-change systems when correctly designed Part geometry, mounting stress and edge finish remain important. Chemical behavior Stable against many chemicals; application compatibility must be checked Cleaning chemistry and service environment should be supplied for review.
