Custom Optical Filters

Together with our supplier Vortex we provide broadband and V-style anti-reflection (AR) coating from 300 nm to 6000 nm. We offer AR coatings service on your optics with an unrivalled rapid turnaround or can also supply “make complete” AR-coated optics with substrates sourced through one of our trusted suppliers. Our AR coatings can be customized to your application’s requirements – contact the AMS Technologies experts today to discuss your customized anti-reflection coating solution! Broadband AR CoatingA number of standard broadband processes covering many spectral regions is available that can also be adjusted for your specific requirements, e.g. the coating’s properties can be moved to a number of different bands if required. Some examples of broadband AR coatings: Broadband AR Coatings    Optimized Wavelength Substrate Average Reflection Within Wavelength Band AR 400-700 nm Glass <0.5% AR 400-900 nm Glass <1.0% AR 400-1100 nm Fused Silica <1.0% AR 400-1700 nm Sapphire <3.5% AR 400-2500 nm Sapphire <8.0%   V-CoatingAs a special type of anti-reflective coating, V-coatings improve transmission in a very narrow wavelength range around the design wavelength. This type of coating is called a "V-coating" because the curve of the reflection over the wavelength resembles the letter "V", with a minimum at the design wavelength. Both single- and multiple-wavelength V-coat processes are available for laser and LED applications covering a range from 300 nm to 6000 nm, with maximum reflection of <0.25% per surface at the designated wavelength. Some examples of V-coatings: V-Coatings     Optimized Wavelength Substrate Reflection V-Coat 633 nm BK7 <0.25% V-Coat 1064 nm BK7 <0.25% V-Coat 1550 nm Sapphire <0.25% V-Coat 3300 nm CaF2 <0.25% V-Coat 532_1064 nm BK7 <0.25% V-Coat 532_1064_1550 nm BK7 <0.25% V-Coat 532_633_780_1064_1550 nm BK7 <0.25%   Infrared AR CoatingInfrared anti-reflection coating can be provided anywhere between 0.7 µm and 6 µm on Glass, Silicon, Germanium, Sapphire, Barium Fluoride, Calcium Fluoride, Gallium Arsenide etc. to suit your specification.

Surface Finish Gold, Aluminium; Mirror Size 2.5x3.6, 16x11 mm; Tilt Angle ±1.5°, ±5°; Reflectivity 95%, 98%; Max. Actuation Current 60, 200 mA Sercalo Microtechnology’s MM series of miniature MEMS magnetic actuated mirrors and deflection units are used for advanced optical beam steering and pointing. These MEMS micromirrors offer large surface areas and are best suited in applications requiring DC pointing together with dynamic scanning. Using magnetic actuation, the 2D micromirrors’ deflection angle is set linearly with the driving current. They are designed for DC operation as well as scanning and can be used for static or dynamic beam steering with a large surface area of up to 16 x 11 mm and up to ±5° deflection. MM2536-2 dual-axes MEMS magnetic micromirrors with gold or aluminium surface finish are operated in open loop and are currently available with a mirror that has a reflective surface of 2.5 x 3.6 mm. These MEMS micromirrors are best suited in beam steering and scanning applications where small size and low power consumption are important. MM-160110-2 fine-pointing dual-axes MEMS magnetic micromirrors have a large reflective surface of 16 mm x11 mm with gold or aluminium surface finish. As an option, the devices can include an internal optical feedback sensor for closed loop operation. Key Features: Large Mirrors: 2.5 x 3.6 mm, 16.0 x 11.0 mm Surface Finish: Gold (Au) or Aluminium (Al) Reflectivity (800 to 2000 nm): ≥95%, ≥98% 2 Actuation Axes Tilt Angle DC (Mechanical): ≤±1.5°, ≤ ±5° Maximum Angle of Incidence: 45° Linear Control Fine Pointing (MM-160110-2) Resonance Frequency X: 330 Hz, 390 Hz (Typ.)
