Aluminum mirrors
Aluminum mirrors offer a high, color-neutral reflectance from UV to IR
Substrates made of glass or plastic are coated with an aluminum layer in a high vacuum. The resulting aluminium mirrors are characterized by a high, colour-neutral reflectance in a spectral range from ultraviolet (UV) to infrared (IR). This makes aluminum coatings particularly suitable for broadband reflectors in the UV to far infrared range.
We can also influence the properties of the aluminum reflectors by applying additional protective coatings. Besides, we offer aluminum enhanced and aluminum protected.
Advantages of aluminum mirrors
- High, color-neutral reflectance from UV to IR
- Aluminium metallization for broadband reflection of UV, VIS and IR radiation
- Resistant to ageing
- Spectral range: UV to IR
- Different angles of incidence
- Substrates: glass (e.g. float glass) or plastics, aluminum, possibly also other metals
Surface mirror aluminum enhanced
We can influence the properties of the aluminum mirrors by applying additional protective layers. For example, we also offer aluminum with a dielectric reinforcing layer (aluminum enhanced / AL enhanced) aluminum enhanced and aluminum with a protective layer (aluminum protected / AL protected).
We can design the enhanced surface mirrors with an aluminum coating and dielectric protective or reinforcing layer for different spectral ranges. We can produce them as aluminium front surface mirrors with an additional dielectric layer for the visual range, but also with a dielectric protective layer specially optimized for the near infrared range to increase reflection. The resulting mirror may also be called enhanced aluminum reflector.
Advantages aluminum enhanced mirrors
- Improved reflection due to additional dielectric layers above the aluminum layer
- Adjustable for different spectral ranges (VIS, NIR, UV)
- Excellent optical imaging quality without double images or ghost image effect
- Efficient reflection of infrared light energy (SEA-NIR)
- Large-format dimensions possible
Application areas aluminum enhanced
- Large-format surface mirrors (e.g. for astronomy)
- Optical components for sensor technology
- Aluminum mirrors for barcode recognition
- Infrared mirror optics
- Cost-efficient replacement for silver coatings
- Cost-efficient replacement for gold coatings (front surface mirrors with gold)
- Optical deflection mirrors for light and lasers
- Cameras
- Optical monitoring devices, also for speed detection (“speed trap”)
- Optics for medical instruments
- Systems for position and orientation detection
Surface mirrors aluminum protected
Aluminum mirrors with a thin protective layer of quartz provide good UV reflection, but also achieve broadband reflection into the infrared range.
Advantages of aluminum protected mirrors
- High reflection in the ultraviolet range
- Broad reflection spectrum from approx. 200 nm - 10 µm
- Good optical properties
- Large-format dimensions possible
Applications of aluminum protected mirrors
- UV mirrors
- UV reflectors
- UV-IR measurement technology
- Deflecting mirrors for UV light
- UV disinfection devices
- UV-NIR-IR broadband mirrors
- Medical devices with ultraviolet light sources, e.g. for UV disinfection
- Replacement for gold-based surface mirrors
FAQ - Frequently asked questions about aluminum mirrors
Aluminum mirrors offer high, color-neutral reflectivity across a broad spectral range from UV to IR and are resistant to aging.
Typical substrates are glass (e.g., float glass), plastics, aluminum, and sometimes other metals.
They are used in UV mirrors, laser scanners, telescopes, sensors, automotive, medical technology, and in the visual field, among other things.
“Aluminum enhanced” refers to aluminum mirrors with an additional dielectric amplifier layer that improves reflection and can be optimized for different spectral ranges
They enable improved reflection, are adjustable for VIS, NIR, and UV ranges, offer excellent optical quality, and can be manufactured in large formats.
These are aluminum mirrors with a thin protective layer of quartz, which offer good UV reflection and a broad reflection spectrum extending into the IR range.
They offer high reflectivity in the UV range, a broad spectrum from approx. 200 nm to 10 µm, and good optical properties.
In large-format surface mirrors for astronomy, optical components for sensors, barcode recognition, IR mirror optics, cameras, and medical instruments.
They are used in UV reflectors, UV-IR measurement technology, UV disinfection devices, and medical devices with UV light sources.
They can replace silver or gold coatings while offering high reflectivity across a broad spectral range at a lower cost.
