Case Study for Bidding

Time: February 2024
Supplier: Saint-Gobain (France)
Buyer: Siemens Factory Automation (Germany)
Product: Low-iron, AR-coated float-glass optical windows for high-speed inspection cameras
Quantity: 3.6 million pieces
Contract Value: USD 32 million
Delivery Timeline: October 2025

Case Study for End Using

End User: Thermo Fisher Scientific (USA)

Application: Integrated as protective windows for laboratory spectrometers and fluorescence analyzers.

Installation Location / Usage Stage

Mounted in front of optical detectors to protect sensors from dust and chemical exposure.
Fixed into sealed instrument housings for consistent optical alignment.
Paired with AR coatings to maximize throughput and reduce stray reflections.

Purpose

Ensures clear optical pathways for accurate measurement.
Protects sensitive sensors and mirrors from contaminants.
Maintains stable performance under high-temperature or chemical-lab environments.

Effect

Increased measurement stability by 14% in repeatability tests.
Reduced maintenance downtime from window contamination.
Improved optical throughput due to high-transmission AR coatings.

Alternative Products
Borosilicate windows offer better thermal resistance but are more expensive.
Fused silica windows provide superior UV performance and ultra-low thermal expansion but at significantly higher cost.
Sapphire windows offer extreme hardness and chemical resistance but are not cost-effective for general optical applications.

Therefore, Float Glass Optical Windows remain the preferred, scalable, and cost-efficient choice for mainstream optical protection, machine vision, industrial sensing, and laboratory instrumentation.
