1. SB270 ORION InSb 2K X 2K FPA Status: Newfirm FPAs in production –Four times the magic of Aladdin! –Nearly all SCAs have > 99% indium bump interconnect yield Good response uniformity Low dark current SCAs currently being mounted on "Engineering" 1 st Generation ORION Packages Package is designed for “plug & play” Upgrades to package available Photoshop of 4Kx4K ORION FPA

2. InSb Spectral Response Fig. 7. QE of large-area InSb SCAs as a function of wavelength. The data obtained by Fowler at NOAO is from a 1K  1K ALADDIN SCA with a single-layer, broad- band AR coating. The data from McMurtry at the University of Rochester is from a 2K  2K Phoenix SCA with a seven-layer AR coating designed to enhance visible response and maintain high QE in theinfrared as well. The smooth curves are polynomial fits to each data set.

3. Quantum Efficiency Module #14 QE uniformity improvements are demonstrated!
