Material and core characteristicsThe sapphire light guide block is made of sapphire crystal in the form of aluminum oxide (Al ₂ O 3) single crystal, which has high hardness (Mohs hardness level 9, second only to diamond),
high wear resistance, high temperature resistance, and corrosion resistance. The light transmittance is over 90%, supporting a wide light transmission band (from near ultraviolet to 7 μ m mid infrared
band),and has excellent thermal conductivity and electrical insulation performance. These characteristics make it perform excellently in optical applications.
Core functions and working principles
This component is a rectangular optical glass (common sizes such as 40x38x8mm or 50x25x15mm), with six sides precision polished; One end is coated with a cut-off filter film,
which filters specific wavelengths of light (such as cutting off light below 575nm and transmitting light between 600-1200nm). Light is output from the other end through total reflection,
while absorbing heat to achieve a "cold compress" effect, reducing the heat and pain caused by laser burning on the skin.
Main application areas
Widely used in IPL (Intense Pulsed Light) laser beauty equipment, such as home and professional hair removal and skin rejuvenation devices. It replaces traditional quartz or K9 glass materials,
enhancing performance - capable of withstanding high-energy lasers, reducing the risk of skin damage, and providing a milder and safer user experience.
Technical parameters and customization options
Size: Customizable, tolerance ± 0.1mm
Surface treatment: The chamfer of the incident surface is less than 0.1x45 °, and the smoothness meets the national standard.
Coating and Enhancement: Supports customization of various cutoff and anti reflective films to further enhance energy transfer efficiency and wavelength selectivity.
Sapphire light guide blocks, with their unique physical properties, have become a key component for improving the efficiency and safety of modern laser beauty equipment.
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.
