I would like to say thanks and express my satisfaction with regards to a couple of jobs recently performed by Rainbow Optics. In the first instance, I needed a set of 3" spherical mirrors fabricated and delivered on an extremely short schedule, short being defined as 10 days including weekends and holidays. The second purchase involved a set of custom prisms. In both instances, I received quality optics ahead of your promised date. I'm happy, my scheduler is happy, my project manager is happy, and most important, my customer is happy. Thanks.

Optics in “Discovery” Space Shuttle

Rainbow Research Optics provides optics that aid space shuttle safety.

RROI supplied several optics that were used in the objective lens assembly of the Laser Dynamic Range Imager (LDRI) system. The system was used by NASA, in the mid 2005, Discovery STS-114 mission, for the on-orbit inspection of the shuttle’s Thermal Protection System (inspection of the tiles). All shuttle flights now utilize RROI’s optics.

For your information, a press release describing Sandia's involvement inthe shuttle mission can be found athttp://www.sandia.gov/news-center/news-releases/2005/aerospace/nasashuttle.html

Meniscus Wedge• National Laboratory

• Diameter: 60.0mm

• Materials: SF11

• Meniscus: S1 convex / S2 concave

• Wedge: 16.9 deg +/-13min

• Lambda/4, 20-10

• AR coated @490-800nm

RROI responded by email to my request for quotation the very same day that I issued the RFQ- already a good sign. The prices quoted by RROI were very competitive with other prices, and the delivery time was by far the best -10 days as opposed to a typical 10 weeks, and this included fabrication of a new test plate, fabrication of the lenses, testing, and AR coating.

Test results supplied with the lenses showed that they were manufactured to well within the tolerances that I specified. This rapid response enabled me to get my portion of the project back on track, and really helped me "save face" with the project manager.

As a result of this excellent service, I have made RROI my preferred vendor for custom optics, and I whole heartedly recommend RROI to my colleagues.

Research Center

• Lens Array

- CXCC lens (SF57)

- Ball lens (BK7)

- CCCX lens (SK5)

• Diameter: 28.0mm (largest lens)

• Radius: 20.0mm CX / 10.0mm CC

• AR coated @850nm

• Difficult alignment

I want to thank you and your colleagues for the excellent job you performed on the ball lens triplet, cell mirrors and cell windows. All of the optics met specification and the lens assembly met stringent tolerances. The lens performance, in particular, was fantastic. You also were timely in the delivery and your coatings are excellent. Overall, your services are the best I have experienced in 20+ years in the optics business.

I plan to describe the lens and its performance in a publication in the near future, and I plan to acknowledge Rainbow Research Optics in that paper. Keep up the great work.
