Description
Our custom‑coated optical glass sheets provide two advanced surface solutions – hydrophobic AF (anti‑fingerprint) and hydrophilic anti‑fog – to suit your specific environment and application. Both coatings are applied to premium optical substrates including soda‑lime, borosilicate, and fused quartz, delivering high transparency, low haze, and excellent optical clarity across the visible to near‑IR spectrum.
The hydrophobic AF coating offers both water‑repellent (contact angle >110°) and oil‑repellent properties, effectively resisting fingerprints, smudges, dust, and skin oils. This easy‑clean, anti‑smudge surface is scratch‑resistant and durable, making it ideal for touchscreen displays, camera lenses, wearables, and automotive infotainment systems. Even after repeated wiping, the coating retains its performance.
For high‑humidity or temperature‑fluctuating conditions, our hydrophilic anti‑fog coating prevents fogging by spreading condensed moisture into a transparent, uniform film. This permanent, scratch‑resistant coating ensures fog‑free visibility for medical endoscopes, surgical windows, laboratory optics, outdoor sensors, and refrigeration displays.
We offer complete customization – glass type, dimensions (up to 500 mm), thickness (0.5–10 mm), edge profiles, and single‑ or double‑sided coating. Tolerances are held to ±0.01 mm for thickness and ±0.1 mm for size. Each batch undergoes rigorous quality control including spectrophotometry, contact angle measurement, and abrasion testing.
Optical Glass Coatings and Their Features
1. Anti-Reflective Coating (AR)
Minimizes light loss and eliminates ghosting by reducing surface reflections. Features include >99.5% transmission at target wavelengths, broadband performance across UV to IR spectra, and excellent durability against abrasion and environmental factors. Essential for lenses and displays.
2. High-Reflective Coating (HR)
Achieves extreme reflectivity (>99.9%) through dielectric layer stacks. Offers negligible absorption/scatter, high laser damage threshold, and precise wavelength specificity. Critical for laser cavities and mirror applications.
3. Beamsplitter Coating
Divides light into reflected/transmitted components with precise ratios (e.g., 50/50). Provides polarization-sensitive or wavelength-specific splitting. Used in interferometry and imaging systems.
4. Bandpass Filter Coating
Transmits narrow wavelength bands while blocking others. Features sharp cut-on/off edges, high out-of-band rejection (OD4+), and stable performance at various angles. Ideal for spectral analysis.
5. Metal Mirror Coating (Aluminum/Protected Aluminum)
Provides broad-spectrum reflection from UV to IR. Aluminum coatings offer ~90% reflectivity, while protected versions add durability through oxide overlayers. Cost-effective for general purpose use.
These coatings enable advanced control over light propagation, reflection, and spectral selection in optical systems, with specific formulations optimized for laser, imaging, or analytical applications.
