Summary
Felix Glass supplied custom low-fluorescence JGS1 UV fused silica optical windows for a North American spectroscopy instrument manufacturer. The quartz components feature high deep-UV transmittance and tight polishing tolerance, with full spectral test reports provided per batch.
This customer success case records the whole-cycle customized manufacturing project of deep ultraviolet fused silica windows delivered by Felix Glass for a professional spectroscopy instrument developer from the United States. The client launched a new high-precision ultraviolet spectrometer product line and needed high-purity fused silica optical windows to guarantee stable spectral detection data. Our optical R&D team completed technical validation, sample trial production and mass production delivery step by step, establishing long-term framework procurement partnership after verifying product performance in customer’s laboratory.
The cooperating American enterprise is a medium-sized high-tech manufacturer focusing on R&D and commercialization of analytical spectroscopy instruments. Its equipment is widely supplied to environmental testing laboratories, pharmaceutical inspection institutions and chemical raw material analysis enterprises across North America. To upgrade the ultraviolet spectrometer series, the procurement team started global supplier screening and put forward strict optical indicators for UV fused silica window substrates.
The previous supplier’s products could not match the deep ultraviolet working environment of the new spectrometer. Three practical problems hindered the product iteration: internal tiny bubbles and stripe impurities caused real-time spectral data offset, conventional polishing technology failed to reach the required λ/10 surface precision, ordinary anti-reflection coating will produce performance attenuation under long-term deep ultraviolet continuous irradiation.
After two rounds of online technical seminars, both parties locked standardized technical parameters for customized fused silica windows. Raw material adopts synthetic high-purity fused silica blank suitable for 190nm~400nm deep ultraviolet band, overall transmittance must keep above 91% within target wavelength range. Surface flatness standard is λ/10, internal inclusion level complies with American MIL-G-9954 industry inspection specification, double-sided dedicated deep ultraviolet multilayer anti-reflection coating is required additionally.
Aiming at three major bottlenecks fed back by the customer, our technical department formulated targeted solving plans. Strict raw material screening eliminates blank with internal bubbles and stripes; ultra-precision grinding and polishing process is deployed to stabilize high flatness; independently optimized deep UV coating formula improves the radiation resistance of film layer and slows down coating aging under long-time ultraviolet exposure.
Production strictly follows fixed processing sequence: raw material screening→CNC contour cutting→rough grinding→ultra-precision fine polishing→ultrasonic high-purity cleaning→vacuum coating→finished product comprehensive detection. Sampling inspection is set after every processing procedure. For this spectrometer dedicated window project, we added one extra full-item detection focusing on ultraviolet transmittance and surface roughness before entering the coating workshop to intercept defective products in advance.
Trial samples were shipped to the customer’s American laboratory for all-index performance testing. All test indicators of customized fused silica windows fully meet the signed technical specification, stable ultraviolet transmittance effectively solves the spectral drifting trouble of their previous generation equipment. The client R&D department confirmed our customized coating has better anti-ultraviolet aging capability compared with former supplier, and approved to launch formal mass production cooperation rapidly.
According to the customer’s quarterly procurement rhythm, we developed exclusive shockproof export packaging solution adapted for transoceanic sea transportation. Two parties signed long-term framework procurement contract afterwards. Felix Glass provides priority production scheduling privilege for urgent orders and sustainable technical supporting service for subsequent optical window iteration upgrade. Within one year after formal cooperation, this customer has issued four successive bulk purchase orders.
The customer sorted out three core advantages of cooperating with Felix Glass: flexible parameter customization capability to match personalized development demands, reliable product consistency during large-batch repeated production, one-stop supporting service covering scheme design, manufacturing and post-project technical consultation. This project also accumulates replicable technical experience for our follow-up UV fused silica window orders from North American analytical instrument industry.
Based on this successful spectrometer window project, Felix Glass can supply diversified fused silica customized products for all types of spectral analysis equipment, including infrared fused silica viewport, ultra-thin UV filter base plate, high-temperature resistant spectroscopic observation window and special-shaped fused silica optical parts. North American equipment manufacturers can submit customized demands on wavelength range, coating type, overall dimension and tolerance requirement, our optical engineers will deliver feasible customized solution within three working days.
