Applications
1. Optical Instruments
Sealing window for optical equipment viewfinders and light paths,
blocking dust and moisture without distorting light transmission to
ensure imaging and detection accuracy. Optical experiment reference
substrate for spectrum and transmittance testing.
2. Industrial Automated Inspection
Protective sight glass for machine vision equipment and inspection
chamber observation windows, blocking cutting fluid and dust while
withstanding typical workshop corrosive conditions.
3. Laboratory Equipment
Observation cover plate for physical and chemical experiments and
reaction equipment visual windows, resistant to routine weak acid
and alkali immersion.
4. Medical & Precision Equipment
Instrument protective sight window and detection equipment
transparent cover plate, meeting cleanroom and dust-free operating
environment requirements.
Advantages over Ordinary Float Glass
Compared to standard float glass, this optical glass sheet offers
significantly higher optical uniformity and flatness without
distortion, precision tolerance machining, and stable light
transmission properties free from refractive deviation. Combined
with moderate chemical corrosion resistance, it is the preferred
choice for precision optical and high-end equipment applications.
