We are leaders in special processing for unique and difficult applications.
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.
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

Test Patterns, and more. Patterned optics used in Optical Systems (Sights),
Machine Vision, Robotics Systems, Metrology Labs, and numerous others.

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.)
