Sapphire Step Prism Irregular Cut Optical Prism Coated Step Plate Optical Component

A sapphire prism is an optical component made from sapphire material. Sapphire possesses extremely high hardness, excellent chemical and thermal stability, as well as good optical properties, making it suitable for various optical systems. Sapphire prisms can be used in ultraviolet, visible, and near-infrared spectral bands, making them a durable and efficient optical material.

Working Principle of Sapphire Prisms

The working principle of a sapphire prism is based on the refraction and reflection of light. Due to the high refractive index and low absorption rate of sapphire material, it can effectively guide and control the propagation path of light. In optical systems, sapphire prisms can achieve light dispersion, reflection, or focusing through their specific geometric shapes. For example, sapphire prisms can be used in spectrum analyzers to decompose composite light into monochromatic light of different wavelengths.

Characteristics of Sapphire Prisms

1. High Hardness and Wear Resistance: Sapphire is one of the hardest minerals in nature, so sapphire prisms exhibit extremely high wear resistance and scratch resistance, making them suitable for use in high-wear environments.
2. Chemical Stability: Sapphire has good corrosion resistance to most chemicals, allowing it to maintain stable performance in harsh chemical environments.
3. Thermal Stability: Sapphire has a low thermal expansion coefficient and high thermal conductivity, enabling it to maintain structural stability under high-temperature conditions, making it suitable for high-temperature optical applications.
4. Optical Transparency: Sapphire exhibits good light transmission in the ultraviolet, visible, and near-infrared bands, making it suitable for various optical systems.
