UR SHARED RESOURCE FACILITY
Laboratory for Laser Energetics (LLE)
Description of Facility:
The Optical Manufacturing Shop has the capability of supplying optical devices in dimensions up to 75 cm. This includes:
Deposition of metal and high laser damage threshold multilayer dielectric thin film coatings. High quality reflectors, polarizers, and antireflection coatings are produced by reactive evaporation with an electron-beam gun onto heated substrates. Ion-assisted deposition routinely supplements this process when required.
- Sol-gel coating for high laser-induced threshold antireflection coatings by dipping or spinning.
- Manufacture of liquid crystal polarizers and wave plates up to 200 mm
- Full metrology for optical and spectral characterization of coatings.
- Laser damage testing of substrates and coatings.
- Ion etching of patterned structures
A wide range of materials may be evaporated in any of similarly equipped chambers: a 72-in. box coater with a 30-in. planetary, a 54-in. box coater with a 22-in. planetary, 28-in. and 25-in. box coaters with a single rotation, and a 19-in. steel bell jar chamber with single rotation. A 46" coater with a single planetary system is utilized for ion-etched work.
Characterization equipment includes an 18-in. interferometer, several spectrophotometers, and optical profilometer, a defect mapper, and microscope.
The services of the Optical Manufacturing Shop are available to any University customer. The present shop rate is $79/hour. Estimates are available by contacting Amy Rigatti. Services may be contracted for by submitting a University requisition or by approving the estimate and providing an account number to bill against by journal entry.
