Step glass is a type of glass material with a special structure that features vertical height differences. It is commonly used in optical instruments, laboratory equipment, medical devices, and other fields. The "step" in this glass refers to the vertical distance between one surface and the other. Depending on the height of the step, step glass can be categorized into the following types:

• Low-step glass: The step height is generally no more than 10 micrometers, making it suitable for high-precision, high-resolution optical instruments such as microscopes and telescopes.
• Medium-step glass: The step height ranges from 10 to 50 micrometers, primarily used in the manufacturing of large optical instruments like spectrometers and interferometers.
• High-step glass: The step height exceeds 50 micrometers, making it suitable for optical components that require a larger surface roughness, such as mirrors and lenses.

• Main Characteristics of Step Glass

  Step glass possesses a variety of excellent properties, making it widely applicable in the fields of optics and precision manufacturing. These include:

  • High light transmittance: Step glass has extremely high light transmittance, effectively allowing light of various wavelengths to pass through with minimal loss, whether it is visible or invisible light.
  • Hardness and durability: Step glass exhibits high hardness, excellent wear resistance, and scratch resistance, enabling it to maintain its performance and appearance under various environmental conditions.
  • Temperature stability: Step glass demonstrates outstanding temperature stability, maintaining its shape and performance across a wide range of temperatures.
  • Chemical stability: Step glass is highly stable against various chemical substances, resisting chemical corrosion and oxidation while preserving its original properties and appearance.
