Right Angle Mirrors
A Right Angle Mirrors, also known as a turning mirror, is a specialized optical component with several unique characteristics and applications. Here’s a summary of the key information about right angle mirrors based on your description:
Design and Function
- A right angle mirror is a triangular prism with a 90-degree angle between two of its faces. It serves the purpose of reflecting incident light at a 90-degree angle, making it useful for changing the path of light in optical systems.
- Incident light typically enters through one short leg of the prism, is reflected by the metallic coating on the hypotenuse (the 90-degree angle face), and exits through the other short leg.
- Right angle mirrors are valued for their ability to efficiently redirect light at a right angle, making them suitable for various optical applications.
Substrate and Coatings
Right angle mirrors are commonly manufactured from BK7, which is a type of optical borosilicate-crown glass known for its optical quality and clarity.
The hypotenuse of the prism is coated with one of the following options:
- Enhanced Aluminum: This coating includes aluminum with a multilayer dielectric overcoat designed to optimize reflectance at specific wavelengths. It provides good reflection in the UV, visible, and mid-IR wavelengths.
- Protected Silver: Recommended for use with visible light.
- Protected Gold: Ideal for applications working with the full IR spectrum. Neither protected silver nor protected gold coatings are sensitive to the angle of incidence or polarization, making them versatile choices.
- They are known for their ease of alignment and can be easily mounted in optical systems.
- These mirrors are often employed in applications where precise alignment and high performance are critical.
- Right angle mirrors are commonly used in compact optical waveguide devices and high-density integrated optics.
They are also useful for reducing the size of optical systems by changing the path of light at a right angle.
Right angle mirrors from your factory have specific quality standards:
- A clear aperture greater than 90% of the length of the optic.
- Dimension tolerance of +0.0 -0.2mm.
- Surface quality with a rating of 40-20, where the first number indicates the brightness of the largest allowable scratch, and the second number refers to the diameter of the largest permissible dig, measured in microns.
- Optional protective bevels with a typical size of 0.2mm x 45 degrees can be added.
