Jiangxi Ootee Optics Co., Ltd fabricates an array of metallic and dielectric optical mirrors to meet your custom specifications and requirements. Optical mirrors basically consist of a polished substrate with a metallic coating or dielectric coating on the front surface (sometimes referred to as first surface mirrors), but different applications require different levels of precision optical mirrors.
Manufacturing limits depend upon the part size and substrate material and should be used as a general reference. Please contact a Sales Engineer, who will gladly discuss our capabilities based on your specifications.
**Please note: reflected wavefront specifications are based on substrate measurements before coating and may differ based on the type of coating applied afterward.
Gold Coated Mirrors
Gold-coated optical mirrors provide the highest reflectivity for infrared (IR) wavelengths, up to 98-99% throughout the infrared spectrum. Optical mirrors coated with gold (Au) are ideal for applications in the 750 – 1500nm wavelength range. Jiangxi Ootee Optics Co., Ltd can custom manufacture gold-coated mirrors to meet the reflectivity and environmental stability requirements for your specific optical mirror applications.
Silver Coated Mirrors
Silver-coated optical mirrors provide excellent reflectivity, between 95-99% even into the far infrared spectrum (and greater than 95% reflectivity from 450nm to beyond 12μm). However, mirrors coated with silver (Ag) may be less ideal for some applications since they can have less than 90% reflectivity in the blue and ultraviolet spectral areas. Fortunately, Jiangxi Ootee Optics Co., Ltd can custom manufacture silver-coated mirrors to meet the reflectivity and light transmission requirements for your specific optics applications — along with protective coatings to help protect silver-coated mirrors from tarnishing.
Aluminum Coated Mirrors
Aluminum-coated optical mirrors are perhaps the most common and least expensive types of optical coating. Aluminum (Al) reflects roughly 88-92% of the visible light spectrum, and greater than 85% reflectivity over a wide range of wavelengths in the UV, IR and visible spectrum. Jiangxi Ootee Optics Co., Ltd can custom manufacture aluminum-coated mirrors — with expert control of the thickness and density of aluminum coatings — to manipulate the reflectivity and light transmission for your specific requirements
Nickel Coated Mirrors
Nickel-coated optical mirrors are relatively insensitive to wavelengths and are ideal for use in scatter-sensitive optical applications that require superior resistance to heat and thermal damage. Nickel (Ni) coated mirrors offer excellent corrosion resistance, hardness (Rockwell C hardness of approx. 49) and uniform thickness. Jiangxi Ootee Optics Co., Ltd can custom manufacture nickel-coated mirrors — with a variety of finishings — to meet the specific requirements of your optics applications.
Chrome Coated Mirrors
Chrome-coated optical mirrors reflect less, absorb more, and are more durable than aluminum or gold and are relatively insensitive to wavelength. Chrome is frequently used as an undercoating in conjunction with other metallic coatings.
Titanium Coated Mirrors
Titanium-coated optical mirrors have low density and high strength, making them ideal for high-temperature environments and high corrosion resistance. Jiangxi Auto Optical Co., Ltd. can manufacture customized titanium-plated optical mirrors to best meet your specific requirements.
