Description
Improper quartz grade or poor processing leads to UV loss, thermal crack and assembly mismatch. Bad UV‑transmission from incorrect quartz material grade Thermal‑crack risk under high‑temperature working environment Non‑standard JGS grade without traceable material certification Poor dimensional accuracy causes sealing‑assembly failure JGS1, JGS2, JGS3 quartz domes with custom geometry for UV sensor, aerospace and underwater optics. Differences of JGS1 / JGS2 / JGS3 fused silica for optical dome applications. High UV transmittance, thermal‑shock resistant custom quartz domes for industrial and aerospace projects. JGS series fused silica provides excellent ultraviolet light transmittance, ideal for UV‑sensor and UV‑detection optical domes. Low thermal expansion coefficient, resist rapid temperature change, fit high‑temperature working scenarios. Fused silica is optically isotropic, no birefringence disturbance for polarization‑sensitive optical systems. Single‑sided / double‑sided AR coating optimized for UV, visible or near‑infrared spectrum requirements. Custom radius, diameter, wall‑thickness and sealing flange geometry according to CAD drawings. Fused silica dome fits medium‑depth underwater use; not recommended for heavy seabed sediment environment due to moderate hardness. Parameter reference for custom JGS1‑JGS2‑JGS3 fused quartz optical domes. Complete self‑production workflow for JGS series fused silica optical domes. Custom‑made JGS fused silica domes for global UV‑optics, aerospace and industrial customers. Precision fused‑silica optical component manufacturer JGS1 / JGS2 / JGS3 material with material traceability Low‑volume sample and mass‑production order support Dimensional, spectral and optical performance testing Drawing review and quotation within 24 working hours A: JGS1 for deep‑UV; JGS2 for general UV‑Vis; JGS3 for near‑infrared application. Our engineer will suggest proper grade based on your spectral requirement. A: Yes. We customize radius, diameter, wall‑thickness and sealing flange according to your CAD files or technical specs. A: Available for medium‑depth underwater scenarios; not suitable for heavy‑sediment seabed because of moderate Mohs hardness. Sapphire is recommended for deep‑sea heavy‑abrasion environment. A: Yes, single‑sided and double‑sided AR coatings optimized for UV‑Vis‑NIR spectral bands are available. A: Sample order:8‑14 working days; mass‑production:18‑25 working days, subject to drawing complexity. Please provide spectral requirement, working condition, dimension drawing or specifications. Our optical engineer will send detailed quotation for you within 24 hours.
