公司简介

Gurley Precision Instruments (GPI) has been in business since 1845. We started in surveying instruments, where we were a global leader in both quality and precision, soon after introducing water current meters in the late 1800s, optical patterns on glass and test instrumentation in the early 1900s, and finally optical encoders in the 1950s, which is presently our largest product line. Our main office and factory reside in Troy, New York, however we have joint ventures in Russia, Lithuania, Slovenia, and China to support our various component and assembly needs.

OPTOGRAPHICS

Optographics is the production of precision masters and the replication of these patterns in metallic depositions or photographic emulsions on various substrates.  At Gurley Precision Instruments, we have taken Optographics from its infancy to the continuously expanding state of the art products we have today. Some of our more standardized Optographic products include:
Reticles, Resolution Targets (including USAF & Sayce), Gratings, Step Wedges, Optical Rulers Field Finders, Rapid Comparators, Encoder Discs & Scales, Apertures and Grids

Lovins Micro-Slide Field Finder and Rapid Comparator Datasheet and Pricing (.PDF File)

General capabilities include:

  • Precision master generation, both linear and rotary.

  • Substrate fabrication including shaping, drilling and grinding & polishing of glass, and cutting and hole punching of film.

  • High vacuum deposition of coatings.

  • Pattern replication from prototypes to high volume on flat, curved, or odd shaped surfaces.

  • Image contrast control and multiple image registration.

  • Assembly, including bonding of encoder discs to hubs and reticle, or scale mounting in holders.

  • Inspection to MIL-I-45208 specifications.

Patterns vary from simple cross hairs and standard resolution targets to sophisticated sighting reticles and registration patterns for commercial, military or aerospace applications.

Other than chrome, we vacuum deposit many other metals for reproducing patterns including nichrome, aluminum, silver, copper, inconel, titanium and gold.

Substrate material is quite varied due to transmission requirements, coefficient of expansion, and other exotic demands.  Besides soda-lime float glass, we use borosilicate crown glass, quartz, fused silica, zinc sulfide, zinc selenide, calcium fluoride, germanium, lithium niobate and sapphire to name a few.
Our vacuum coating area can apply special coatings such as magnesium fluoride, silicon monoxide, cerium fluoride and zinc sulfide for their anti-reflective properties, or for their ability to protect less durable coatings like aluminum, silver and gold.
Our years of experience and creative engineering staff give us the ability to tackle your most challenging optographic problems with a degree of success unequaled in the industry.

OPTICAL COATINGS

Gurley Precision Instruments offers U.S. made standard and custom coatings at overseas prices. Our coating chambers and expert staff provide a variety of custom coatings to meet your specifications for Visible and Near IR applications. We specialize in offering custom designed coatings on our substrate or yours. 


Features and capabilities include:

  • Large selection of design coatings

  • High durability and Laser damage threshold (Typical: 20J/cm2 -20ns pulse)

  • Anti-Reflective (AR): Single or multiple layer Magnesium Fluoride (MgF2 ); “vee” coats; broadband and dual range multi-layer coatings

  • Reflective Mirrors: Aluminum, Chrome, Inconel and Dielectric

  • Data Certification provided with every order

  • Coatings optimized to your custom requirements



Optical Coating Types and Specifications:

Anti-Reflection Coatings

NarrowBand AR Coating (Vee-Coat)  Optimized for single wavelength (ie. 450nm, 550nm, 650nm). Typically R<0.10% at the customer’s specified visible region wavelength (non-absorbing, high efficiency for high laser damage threshold)

NarrowBand AR Coating with SiO2 (Vee-Coat)  Optimized for single wavelength, an SiO2 coating protects the AR coating. Typically R<2% at the customer’s specified visible region wavelength (non-absorbing, high efficiency for high laser damage threshold)

Broadband AR Coating   Broadband AR coating for the visible photonic region. Typical R<0.5% between 450 to 700nm.

Low Cost Broadband AR Coating   Broadband AR coating for the visible photonic region but reflectance spec is loosened to R<1.0% between 450 to 700nm. Because of the higher reflection specification, this is a lower cost alternative.


Reflective and Dielectric Mirror Coatings

Protected Aluminum Coating    Aluminum with SiO2 protective overcoat. R> 88% 450-700nm. Other configurations to your specific requirements are available.

Enhanced Aluminum Coating   Aluminum overcoat with multiple protective coatings. Typical reflectivity to 95% in the visible range of 450 to 700nm. Call with your specifications.

Dielectric Mirror Coating   GPI offers dielectric coating capabilities for various wavelength and light regions designed for your requirements (ie. R>= 99.9% @1550-1650nm). 


Other Coatings

In addition to the above product capabilities, we also provide the following: Double Wavelength AR Coatings, Beamsplitters, Dichroic Mirrors, Neutral Density Filter Coatings, patterned images and other custom designs per your specifications.
