The light guide block works based on the principle of internal total reflection, which can effectively convert non-uniform light sources into uniform light sources without being affected by spectral characteristics. Compared to square light guides, its hexagonal structure reduces light loss by up to 35%. For light sources with small numerical aperture (NA) values, longer light pipes are required to achieve uniform light distribution; Light sources with larger numerical aperture values only require shorter light tubes to meet the requirements.
Main application areas
BK7 light guide block is widely used in various high-precision optical scenes:
Laser technology application: Suitable for laser focusing applications with wavelengths of 650-1000nm, ensuring minimal wavefront distortion. In 1064nm laser systems, N-BK7 plano convex lenses and other components are widely used.
Industrial measurement: used for high-precision retroreflectors, suitable for scenarios such as long-distance laser ranging and road laser speed measurement.
Its high-strength packaging shell (aluminum alloy, stainless steel or engineering plastic) has anti vibration and anti impact performance, and can adapt to complex working conditions in industrial workshops.
Laboratory Optics: The N-BK7 right angled prism is polished to a surface flatness of λ/8, suitable for high-precision laboratory applications.
Excellent performance in general laboratory applications in the visible and near-infrared ranges.
Special environmental applications: Some models adopt IP65/IP67 sealing structure, which can effectively block dust and water vapor, suitable for outdoor meteorological monitoring, ocean exploration and other humid and dusty environments.
Precautions
Cleaning and maintenance: Use a soft cleaning cloth and specialized cleaning agent to clean and avoid scratching the surface.
Storage environment: Store in a dry, well ventilated environment to prevent moisture and mold.
Usage: During use, avoid severe vibration and collision to avoid affecting its optical performance.
