Alflex™ (UV, B-VIS, B-NIR)

Versatile Aluminium Mirrors, giving an excellent stable Performance

The Alflex™ mirror family has proven itself many times over due to its hardness and durability. Depending on applications the Alflex mirrors are generally insensitive to polarization and angle of incidence over wide wavelength ranges. All types of Alflex™ are equipped with protection layers.

Benefits

• Wide-band, high-reflective and durable metallic mirror coatings
• Designed specifically to meet demands of customer systems (e.g. patterned mirrors)
• Engineering design support
• Excellent environmental stability (environmental testing capabilities in-house)
• Low angle of incidence dependency
• Suited for applications with temperature sensitive substrates
• EU RoHS directive compliant

Applications

• All reflective optics at UV, VIS and NIR
• Optical sensors and instruments
• Metrology & Inspection (e.g. Spectrometer)
• Safety & Security
• Technical Lighting
• Automotive Lidar ranging systems
• Space applications (qualification heritage available for Alflex™)

Technical Data

Substrate type

Floatglass, other substrates e.g. plastic or metal on request.

Alflex™ are applicable as well on customer supplied substrates.

Cleaning

Alflex™ withstands immersion in acetone, ethanol, etc., as specified in MIL-C48497, para. 4.5.4.2. It can be cleaned with a soft cotton cloth soaked in mild soapy water, ethanol or other non-abrasive substances.
