  • SUBSTRATES for UV-VIS-IR & X-RAY:
      Optical Glass (Float Glass, Crown Glass, B270, BK-7, Filter Glass and others)
      UV materials (Synthetic Quartz / Fused Silica)
      IR materials (Zinc Sulfide, Zinc Selenide, Germanium)
      Machined Ceramic Materials; and new or developmental materials (BBO, KNSBN, KN, KTA, KTP, LBO, Lithium Niobate, NYAB, Nd:YvO4).
      Patterns also on Metal, Plastic or Acrylic substrates.

    • COATINGS: Patterns on glass can be delineated within numerous Coating Materials: Chromium, LR "Black" Chrome (THREE versions), Aluminum, Titanium, Nickel, Inconel, Copper, gold, Silver (protected or enhanced), ITO and Other Dielectrics. Anti-Reflection Coatings include MgFl, SiO2, BBAR and more. Absorptive, Band Pass Filters, Specular Reflective or Diffusion effects possible.


    • ETCH AND FILL PROCESSING: Pattern etched within the Glass Surface for edge lighted applications and/or Filled with Epoxy, Conductive Epoxy or Cermet, Fired Ceramic Glaze or Other durable materials.


    • chip
    • CLEAR OPTICAL PATH: Patterns fabricated through metals by Photo Chemical Etching, Electroforming and Electroless deposition.


    • FEATURES: With extremely precision PHOTOTOOLING using Proprietary processes in Class 10 Clean Room Facilities FEATURES TO 0.000 040" [0.001mm] can be replicated.


    • APPLICATIONS for Microscopy, Measurement, Position, Alignment, Resolution, Video Test Patterns, and more. Patterned optics used in Optical Systems (Sights), Machine Vision, Robotics Systems, Metrology Labs, and numerous others.

  • Clean Room Evaporation Chamber Current thin film coating capabilities:

  • METALLIC COATINGS: We can deposit any metallic film by means of evaporation or sputtering (Chromium, Low Reflection Chromium, Titanium, Aluminum, Silicon, Silver, Gold, Indium Tin Oxide, Copper, Inconel, Nickel, Nichrome, and Tungsten) onto various substrates, including glass and most ceramics. The number of parts which can be coated at one time varies with the size of the part, the allowable fixture holding or "rail" marks, and other factors. Standard coating thicknesses range from 200 Angstroms to 5 Microns, dependent upon internal stresses of the metal film and other factors.
  • LOW REFLECTION CHROMIUM COATING: "Black Chrome" or Chromium Oxide is applicable when it is desired to reduce the Reflectivity of the metal at the coating/air boundary. Max Levy Autograph, Inc., has separately developed proprietary processes to allow Low Reflectivity of the Black Chrome at the substrate/coating boundary. It is thus possible to have Low Reflection Chrome both "looking through" a glass AND "looking at" the coating surface from the air side. For the coating/air application, the Low Reflection Chrome will exhibit 3% Reflectivity at the design ("tunable") wavelength and an average 10% Reflectivity across an inclusive 100nm bandwidth. For glass/coating applications, the Low Reflection Chrome will exhibit 10% Reflectivity at the design wavelength and an average 15% Reflectivity across an inclusive 100nm bandwidth.
  • DIELECTRIC ANTI-REFLECTION COATINGS: We can fabricate a V coating for Visible (400-700 nm) and Near InfraRed (750-1200 nm) light wave lengths. The V coating will decrease the reflectivity of the substrate to 0.5% at the design wavelength and will have a 125 nm bandwidth exhibiting less than 1% reflectivity. A single layer of MgF2 coating can be deposited which will have its minimum reflection of 1.5% at the design wavelength and an average of 2.5% reflectivity across a full 350 nm bandwidth. These coatings will fully comply with the durability requirements of MIL-C-675. We are developing processes and fabrication techniques for High Efficiency Broad Band Anti-Reflection coatings. Additional equipment and capabilities will be available in the near future.
  • DIELECTRIC REFLECTIVE COATINGS: This type of coating can be fabricated to have an average 95% Reflectivity across a 350 nm bandwidth. These coatings will work for Visible and Near IR light wavelengths.
  • FILTER COATINGS: Low pass, high pass and bandpass filters can be fabricated across the Visible and Near IR light wavelengths.

  • (Certain evaporation techniques and combinations my not comply with some durability requirements of MIL specs.)
