The transmittance of BK-7 glass can reach over 90%, and it exhibits excellent performance in the visible to near-infrared wavelength range, which enables the light guide block to efficiently transmit light and reduce energy loss. In addition, its excellent mechanical performance can adapt to complex working conditions, such as maintaining structural stability in high temperature or vibration environments, further expanding its application scenarios.

The main application areas of BK7 light guide block

Medical beauty equipment: In beauty instruments, the BK7 light guide block serves as the core component of the light guide column, used to transmit laser or strong light energy, ensuring treatment accuracy and safety. The material has high purity and good optical uniformity, and is widely used in devices such as photon rejuvenation and laser hair removal.

Optical instruments and sensors: In precision optical systems, BK7 light guide blocks can be used as optical path calibration or signal transmission components, such as auxiliary light guide structures for microscopes and optical signal transmission modules for industrial sensors. The six sided polishing process can reduce light reflection loss and improve system sensitivity.

Consumer Electronics and Lighting: In some high-end consumer electronics (such as smart device indicator lights) and customized lighting devices, BK7 light guide blocks are used to optimize light distribution, achieve uniform light emission or directional conduction, and enhance product visual effects.

Market and Production Overview of BK7 Light Guide Blocks

Market supply and selection: Currently, there are various supply channels for BK7 light guide blocks in the market, including standardized products provided by e-commerce platforms such as Taobao, as well as customized services that can process products with specific sizes, coating or polishing accuracy according to customer needs.

Production technology requirements: The production of BK7 light guide blocks requires strict material screening, cutting, grinding, and polishing processes. Some high-end products also require vacuum coating (such as anti reflective films) to further enhance optical performance.

Precautions for purchasing BK7 light guide block

Clear performance requirements: Determine the required parameters such as transmittance, dimensional tolerances, and surface smoothness based on the application scenario. For example, medical equipment needs to choose high-purity BK7 material without bubbles and impurities, while for ordinary light guiding scenarios, a more cost-effective alternative K9 can be considered.

Supplier qualification verification: Priority should be given to enterprises that have passed ISO9001 and other quality system certifications to avoid purchasing low-priced and inferior products. When purchasing on e-commerce platforms, it is necessary to refer to user reviews and product testing reports.

Customized communication: If special specifications are required (such as irregular cutting, coating), the feasibility of the process and delivery cycle should be confirmed with the supplier in advance to ensure compliance with project schedule requirements.

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.
