Join OEOSC
OEOSC welcomes all companies, organizations and individuals interested in supporting standards development for optics.

Join ASC OP
Companies, organizations, and individuals who are materially interested in the development of American National Standards for optics are encouraged to apply for membership in ASC OP.

Join TAG to ISO TC172
All U.S. national interested parties who are directly and materially affected by the activity of the U.S. TAG may apply for membership.

Please provide your contact information:

ASC OP "Committee for Optics and Electro-Optical Instruments"
American National Standards for optics are developed and maintained by ASC OP. Work is conducted through a series of task forces, each of which is responsible for standards in a particular category. Please select the task forces in which you would like to participate.

TF 1 – Optical Glass
TF 2 – Surface Imperfections
TF 3 – Measurement of Optical Wavefronts
TF 4 – Optics Drawings (OP1.0110)
TF 5 – Aspheric Optics
TF 6 – Infrared Materials

Optical technical experts who establish the official US position with respect to international standards do so through the ANSI/OEOSC Technical Advisory Group (TAG) to ISO/TC 172 whose title is “Optics and photonics.” TC 172 has seven subcommittees to cover various segments of optics. Please check those working groups for which you have expertise and are willing to actively participate.

SC 1 - Fundamental Standards
WG 1 - General optical test methods
WG 2 - Preparations of drawings for optical elements and systems
WG 3 - Environmental test methods
WG 4 - Data transfer: contents and management

SC 3 - Optical Materials and Components
WG 1 - Raw optical glass
WG 2 - Coatings
WG 3 - Characterization of IR materials

SC 4 - Telescopic Systems
WG 1 - Binoculars, monoculars and spotting scopes
WG 3 - Astronomical telescopes
WG 5 - Night vision devices

SC 5 - Microscopes and endoscopes
WG 3 - Terms and definitions
WG 6 - Endoscopes
WG 8 - Immersion media for light microscopy
WG 9 - Optical performance of microscope components

SC 6 - Geodetic and surveying instruments

SC 7 - Ophthalmic optics and instruments
Please contact the Administrator of the ANSI/Z80 Committee for membership information.

SC 9 - Electro-Optical Systems
WG 1 - Terminology and test methods for lasers
JWG 1 - Joint ISO/TC 172/SC 9-IEC/SC 47E WG : Diode lasers
WG 2 - Interfaces and systems specifications for lasers
WG 3 - Safety
WG 4 - Laser systems for medical applications
WG 5 - Laser systems for general applications - STAND BY
WG 6 - Optical components and their test methods
WG 7 - Electro-optical systems other than lasers

In order to ensure that all interests are represented in the development of standards, ANSI requires that OEOSC define specific interest groups that pertain to the field of optics, and to report committee membership by those interest groups. Please select the interest group that best describes you.

OEOSC was created for the single purpose of managing the national standards committee and the advisory group to the international standards committee. OEOSC finances its dues to ANSI, the tracking of standards correspondence, and meeting arrangements through the sales of published standards and soliciting participation fees from those who are members of ANSI/OEOSC TAG to ISO/TC 172, and OP. Fees are assessed based upon four types of participants:

• Self-employed or academic experts
• Individual company experts
• Trade organizations and professional societies
• Corporate sponsors

Please select the one fee that corresponds to your status.
