Metrology

Precision Optical’s metrology capabilities are its foundation.  It is a common phrase in the optical industry “If you can’t measure it, you can’t make it”. Precision Optical utilizes its state of the art metrology to verify sub arc second angles, less than 1 micron in optical path difference, flatness and TWE of λ/40, transmission and reflectance for both S and P polarization at angles of 0 – 70º AOI. Every measuring device is rigorously maintained and calibrated per ISO 9001:2000. See below for a general list of metrology equipment and measurement capabilities.

INTERFEROMETRIC TESTING

WYKO 6000 DUAL BEAM INTERFEROMETER WITH 12.0" APERTURE

Precision Optical’s interferometry capabilities utilize 4D, WYKO, ZYGO, and ESDI technologies.  We have the ability to measure nearly any type of optical component, specializing in tight angle-toleranced prisms and cornercubes.  Our range of sizes we can measure vary from 5mm – 300mm.  We can supply interferogram printouts, as well as datasets on disk or via e-mail in the following formats:  4D (.h5), Wyko/Veeco (.opd), Opticode (.map), Metropro (.dat), CODE V (.int) or ESD, HDF4 (.HDF).

• (4) WYKO 6000 FULL PHASE SHIFT INTERFEROMETERS WITH VEECO AND 4D ANALYSIS SOFTWARE – 0.5” TO 12.0” APERTURE
• WYKO 100 FULL PHASE SHIFT WITH VEECO ANALYSIS SOFTWARE  5MM TO 25MM APERTURE
• ZYGO GPI XP 4.0” APERTURE WITH METROPRO ANALYSIS SOFTWARE

SPECTRAL TESTING

Perkin Elmer Lambda 900 & 950

Our spectrophotometers include a Perkin-Elmer 900 with PELA-1030 10° – 70° variable reflectance attachment and a Perkin-Elmer 950 with Universal Reflectance Attachment (URA), and General Purpose Optical Bench (GPOB).  Both instruments and our accessories (which are interchangeable on both machines) give us the ability to cross-check machines, and virtually perform any type of transmission or reflectance measurement from 200nm – 3200nm with polarization capabilities. 

• PERKIN ELMER LAMBDA 900 UV/VIS/NIR WITH VARIABLE ANGLE ABSOLUTE REFLECTANCE ATTACHMENT, TRANSMISSION & REFLECTANCE FOR S & P FROM 0 - 70º AOI
• PERKIN ELMER LAMBDA 950 UV/VIS/NIR WITH ABSOLUTE REFLECTANCE ATTACHMENT AND OPTICAL BENCH FOR SAMPLE, COMPONENT AND ASSEMBLY TESTING

MECHANICAL AND ANGULAR TESTING 

Davidson Autocollimator and Alignment Telescope w/digital ccd

With Precision Optical’s interferometers, auotocollimators and alignment telescopes we routinely manufacture components and assemblies with sub arc second accuracy. Our OGP Avant-Zip CMM with Measuremind 3D and multisensor capabilities allows for mechanical measurement accuracy of < 2.5microns with minimal handling.

ENVIRONMENTAL TESTING

Temperature Chamber

All of Precision Optical’s mechanical, interferometric and spectral testing is performed in a stabilized and regulated temperature of 70 +/- 5 deg and humidity 40 +/- 10% RH. We also perform environmental testing for the integrity of our optical coatings and assemblies.

• PRECISION OPTICAL HAS THREE THERMAL CHAMBERS
• THERMAL CYCLING FROM -80deg F to +160deg F.
• HUMIDITY INFLUENCE – 95 TO 100º RELATIVE HUMIDITY
