National Capital Section
of the Optical Society of America

 Fifth 2016-2017 meeting of the
National Capital Section of the Optical Society of America

Tuesday, February 21st, 2017, 6:00 PM

At the NASA/Goddard Visitors Center, ICESat Road, 
Greenbelt, MD


Speaker: Javier Del Hoyo, Code 551, Optics Branch

 Goddard Space Flight Center

 “High Performance Broadband Coatings”


High-performance broadband coatings have been identified as an “Essential Goal” in the technology needs for the Large UV/Optical/IR (LUVOIR) Surveyor Observatory. The primary constraint in the optical thin film coating design is attenuation in the Lyman-Alpha Ultraviolet range of 100-130 nm. The design concept of LUVOIR consists of a primary and secondary mirror with various sub-instruments analyzing different electromagnetic bands including a high-resolution UV spectrograph.  In this talk, I will describe various deposition methods and coating designs including broadband reflectors and band-pass filters that we are developing in the Thin Films Coating Lab at NASA GSFC. I will discuss the current state of the art coatings in the Lyman-Alpha Ultraviolet range as well as recent developments and research to maximize the throughput in the LUVOIR instrument design.

Mr. Javier Del Hoyo earned his B.S. in Optical Science and Engineering from the University of Arizona in 2009 and his Master’s Degree in 2013. His thesis work consisted of topics in optical fabrication including surface figure and surface finish optimization and characterization. Prior to entering NASA GSFC, he worked at University of Arizona Fabrication Shop where he specialized in optical figuring and testing. He started working at NASA GSFC as a pathways student and converted to a full time employee upon graduating in 2013 where he has specialized in optical thin film deposition and design to support various missions and proposals from the ultraviolet to the Infrared spectral regions.

Jim Heany,

DIRECTIONS: to NASA/Goddard Visitor Center, Greenbelt, MD

From Washington, DC:

Take the Baltimore-Washington Parkway (Rt. 295) north to Greenbelt Road (Rt. 193).  Take Greenbelt Road east for approximately two miles.  The main gate will be on the left at the first traffic light after Cipriano Road.  Continue on to the next traffic light and turn left onto ICESat Road (formerly Soil Conservation Road).  Take your first left to reach the Visitor Center.


From Baltimore:

Take the Baltimore-Washington Parkway (Route 295) South to the Beltsville Agricultural Research Center.  Exit at Powder Mill road, turn left and go under the bridge.  Turn right at the first traffic light and go about 3 miles to Goodluck Road and turn right when you reach Greenbelt Road.  Take your first right at ICESat Road, which is what this section of what was Soil Conservation road is now called.  Take your first left to reach the Visitors Center.
