An Optical mirror is an optical element that reflects light.
It is composed of one or more reflecting surfaces, such as spherical, flat or aspherical surfaces. Reflecting the required spectrum according to the design requirements, Optical mirror is widely used in astronomy, physics, optics, laser processing, medicine, industry and other fields.
A optical mirror utilizes the principle of reflection to change the direction of light. After reflection, the light retains its original color and frequency. The reflective surface of the mirror can be either flat or curved, and the material can be metallic or non-metallic.
Optical filters, on the other hand, are based on the principles of optical interference and transmission. Different colors and frequencies of light are attenuated or filtered, allowing only specific colors or frequencies to pass through. Filters are typically composed of a series of multilayer thin films, and the thickness of these films can be controlled by adjusting the deposition time.
Optical mirrors come in various types:
Plane Mirrors: Flat surfaces used to change light direction, following the law of reflection. Widely used in research, instruments, and daily applications.
Spherical Mirrors: Include convex (diverge light) and concave (converge light) mirrors, essential in imaging and laser systems.
Aspherical Mirrors: Non-flat, non-spherical surfaces like parabolic and hyperbolic mirrors, reducing aberrations and improving image quality.
Right-Angle Prism Mirrors: Anti-reflective and reflective coatings, easy to install, used in various devices.
Off-Axis Parabolic Mirrors: Segments of parabolic surfaces, ideal for focusing parallel beams, used in femtosecond pulse lasers.
Hollow Roof Prism Mirrors: Composed of right-angle prisms and a rectangular substrate, offering high flatness and good optical performance.
Metal-Coated Mirrors: Metal coatings (aluminum, silver, gold) for broadband reflection, requiring protective coatings in humid environments.
Dielectric-Coated Mirrors: Multiple dielectric layers for specific wavelength reflection, high reflectivity, and low absorption, used in precision optical systems.
Optical mirrors have a wide range of applications across various fields, including:
Scientific Research: Optical mirrors are crucial in laser experiments, optical experiments, and spectroscopy for guiding or changing the direction of light.
Optical Instruments: In devices such as telescopes and microscopes, mirrors are used to reflect and direct light, ensuring the proper functioning of the equipment.
Industrial Applications: Mirrors are used in laser cutting, laser printers, and other equipment to precisely control laser beams, enhancing processing accuracy and efficiency.
Life Sciences and Biomedical: In microscopes and telescopes, mirrors are used for high-precision imaging, reducing aberrations and improving image quality.
Semiconductor and Metrology: In semiconductor manufacturing and precision measurement, mirrors are used for bending light paths and controlling beams.
Machine Vision and Photovoltaics: In machine vision systems and photovoltaic devices, mirrors are used to adjust and optimize light paths.
