Core Features

Optical performance

High transmittance: Excellent transmittance in the 600-1200nm wavelength range, and can achieve specific wavelength cutoff (such as cutoff below 575nm) through coating.

High refractive index (1.762-1.770), superior to quartz glass (1.46), suitable for high refractive index demand scenarios.

Physical and Chemical Properties

High hardness (Mohs hardness 9, second only to diamond), scratch resistant and wear-resistant.

High temperature resistance (melting point 2050 ℃) and corrosion resistance (strong acid and alkali resistance), suitable for harsh environments.

Thermal conductivity

Single crystal structure has high thermal conductivity and can withstand high-energy lasers, avoiding thermal damage.

Typical Applications

Medical beauty equipment

IPL/DPL laser beauty device: As a light guide window, it transmits 600-1200nm laser through total reflection for hair removal, skin rejuvenation and other treatments.

808nm semiconductor laser: Sapphire light guide block can withstand 2000W laser power, improving treatment efficiency.

Industry and Research

Laser medical equipment:such as optical waveguides and cones, require high-precision optical polishing and coating.

Infrared/UV optical window: suitable for high temperature, high pressure or corrosive environments.

Processing and Customization

Six sided optical polishing is required, with the end face coated with a cut-off filter film (such as 530-1200nm anti reflective film).

Support customized shapes (rectangular, conical, etc.).

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.
