Bk7 Glass Plate
Inquiry
Product introduction
BK7 quartz sheet is a common optical glass material that is widely used in various optical systems. It belongs to a borosilicate optical glass, which has excellent light transmission and processing characteristics, and is one of the basic materials for many optical components (such as lenses, prisms, windows, etc).
Product parameters
Main properties of BK7 glass
| Property | Description |
|---|---|
| Transmission Band | Visible to near-infrared (approximately 380nm - 2500nm) |
| Thermal Expansion Coefficient | Moderate (~7.1×10⁻⁶ /°C), suitable for general temperature-controlled environments |
| Refractive Index (nd) | Approximately 1.5168 (at a wavelength of 587.6nm) |
| Abbe Number (Vd) | Approximately 64.2, with low dispersion |
| Chemical Stability | Good water resistance, acid and alkali resistance, suitable for most industrial environments |
| Mechanical Strength | Lower than quartz, but still has good machinability and durability |
| Cost Advantage | Specialty optical materials that are more economically priced than fused silica or sodium fluoride |
