B270 Borosilicate Glass Optical Windows for Pressure Sensors and Display Covers

B270 Borosilicate Glass Optical Windows for Pressure Sensors and Display Covers

Material & Core Properties:
These windows are precision-manufactured from B270 glass, a high-clarity soda-lime borosilicate widely used for its balanced performance and cost-effectiveness.

• High Optical Clarity & Transmission: Offers excellent light transmission (>91%) across the visible spectrum (380-780nm), ensuring minimal signal attenuation for sensors and clear viewing for displays.

• Superior Chemical & Mechanical Durability: Possesses good resistance to water, acids, and alkalis, along with a hardened surface that provides better scratch resistance than many standard glasses, ensuring long-term integrity.

• Thermal and Pressure Stability: Exhibits good thermal shock resistance and can be engineered to withstand significant pressure differentials, making it suitable for sealed sensor housings.

• Precision Fabrication: Available with fine-ground edges, precise thickness tolerances, and can be supplied with custom anti-reflective (AR) or conductive coatings (e.g., ITO) as needed.

Primary Function:
These components serve as robust, optically transparent barriers. Their core functions are:

• Environmental Sealing: To protect sensitive internal electronics, sensor diaphragms, or display elements from dust, moisture, fluids, and corrosive atmospheres.

• Optical Transmission: To allow the unimpeded passage of light for visual inspection, optical sensing, or backlighting while maintaining a sealed environment.

• Structural Interface: To provide a rigid, flat surface that can be permanently bonded or sealed to instrument housings, often forming part of the pressure boundary itself.

Key Applications:

• Pressure & Level Sensors: As transparent, pressure-resistant viewports or protective covers for optical or mechanical sensor elements in industrial, automotive, and marine environments.

• Instrumentation Display Covers: Protecting gauges, touchscreens, and indicator panels on medical devices, industrial control panels, and outdoor equipment.

• Housings & Enclosures: Serving as inspection windows for electrical cabinets, laboratory equipment, and machinery where internal monitoring is needed.

• Consumer Electronics & Appliances: Used as durable lens covers for indicators, scanners, and displays.
