What are Borosilicate windows?
Borosilicate windows are common optical windows made from borosilicate glass.
They are well-known for excellent thermal resistance, chemical durability, and cost-effectiveness.
These windows have good transmission in the visible and near-infrared environments.
They are suitable for various scientific, industrial, and commercial optical applications.
Advantages of the windows
- Excellent Thermal Stability:
Borosilicate glass has a very low coefficient of thermal expansion. It ensurs stable performance under rapid temperature changes.
- High Chemical Resistance:
Resistant to acids, solvents, and most harsh environments, which extends the window’s lifetime.
Resistant to chemical corrosion.
- Cost-Effective Material:
More economical compared to fused silica or sapphire windows while still providing reliable optical performance.
- Good Transmission:
Provides high transmittance in the visible and NIR wavelength range, suitable for general optical applications.
Applications of Borosilicate Windows
- Laser and Optical Systems
Used as protective windows in lasers, optical instruments, and imaging devices.
- Microscopy and Imaging
Make clearer optical paths for microscopes, cameras, and other imaging systems.
- Industrial and Laboratory Equipment
The Borosilicate windows are ideal for laboratory instruments, analytical devices, and process monitoring.
- Lighting and Display Technologies
High-temperature lighting systems, projection systems, and display devices.
- Protective Covers
Serves as durable protective covers for sensors, detectors, and mechanical systems exposed to harsh environments.
