Product Case Studies

When light is incident from one medium (such as air) to another medium (such as glass), it undergoes refraction. In a right angled prism, total internal reflection can occur when light enters the interface between glass and air at a sufficient angle. This total internal reflection can cause light to reflect once or twice inside the prism, thereby changing the direction of light propagation.

characteristic

• Efficient light transmission：Due to the high efficiency of total internal reflection, right angle prisms can transmit light with almost no light loss.
• Change in Image Direction：A right angled prism can change the direction of light, allowing the image to rotate 90 or 180 degrees, which is very useful for correcting image orientation.
• Compact design：Right angle prisms have a compact design and are easy to integrate into various optical systems.

application

• LASER SYSTEM：Right angle prisms are commonly used to change the direction of laser beams to meet specific design requirements.
• Optical measuring equipment：In optical measurement equipment, a right angle prism is used to change the direction of light for measurement and calibration purposes.
• camera viewfinder：In DSLR cameras, a right angle prism is commonly used in the viewfinder to correctly display the image seen through the lens to the camera
• optical instrument：Many optical instruments, such as microscopes and telescopes, use right angle prisms to change the direction of light in order to optimize device design and performance.

advantage

• Efficient light transmission with almost no loss of light energy.
• Capable of accurately changing the direction of light, suitable for image direction correction and adjustment.
• Compact structure, easy to integrate into various optical systems.

In summary, a right angle prism is an important optical component that plays a crucial role in many optical systems and devices. By utilizing the principle of total internal reflection, a right angle prism can efficiently change the direction of light propagation while maintaining high-quality light transmission, meeting the needs of various optical applications.
