DESCRIPTION

DESCRIPTION
x

These K9 optical glass rectangular substrates are manufactured from high-quality K9 optical glass, a widely used optical material known for its excellent transparency, stable optical properties, and cost efficiency. K9 glass provides optical performance similar to BK7 in the visible spectrum, making it a reliable and economical choice for laboratory and optical applications.

Multiple thickness options are available, including 0.4 mm, 0.7 mm, 1.0 mm, and 2.0 mm, allowing the material to be used in a wide range of research and engineering environments. Custom sizes, shapes, and thicknesses can also be manufactured according to specific project requirements.

Due to its high visible light transmission, good optical homogeneity, and stable refractive index, K9 optical glass is widely used in experimental substrates, optical components, protective windows, and general laboratory research applications.

Borosilicate Glass

borosilicate glass sheets are engineered for applications where heat, chemical exposure, and dimensional stability cannot be compromised. Used extensively in laboratories, industrial furnace windows, scientific instrumentation, and precision optical assemblies, borosilicate glass has remained the industry standard for over a century due to

We offer borosilicate glass in pre-cut sizes, full sheets, and custom cut-to-size formats to meet laboratory, engineering, and industrial specifications.

Key Features
Low Thermal Expansion (~3.3 × 10⁻⁶ /K)
Minimizes stress from temperature fluctuations and ensures dimensional stability in high-heat environments.

Excellent Chemical Resistance
Resistant to acids, laboratory reagents, solvents, and many corrosive media.

High Thermal Shock Resistance
Withstands rapid temperature transitions without fracture.

High Optical Clarity
Strong visible light transmission with stable optical performance.

Mechanical Stability
Good hardness and structural strength for substrates, windows, and instrument components.

Fabrication-Compatible
Suitable for CNC cutting, drilling, edge grinding, polishing, coating, and custom machining.

Perfect For
Laboratory Equipment · Furnace Observation Windows · Optical Windows · Scientific Instruments · Microfabrication Substrates · Engineering Components · Process Equipment

Custom Processing Available
