24/Apr/2015 added index of CNGS and Nd:CNGS, per results of SKLCM/ICM Shandong University. These are two CGG-type laser crystals that could be promising as solid-state laser crystals due to good mech properties, low CTE, high specific heat andd other attributes. Both ordinary and extraordinary indices provided.

15/Mar/2015 updated ray tracing with full meridional, tangential, and skew rays

24/Feb/2015 released beta version of ray tracing for optical simulation.Full rigorous ray tracing with up to four surfaces an arbitrary angles.

1/Feb/2015 added index of Ge25Sb10Se65 thin films at various deposition pressures. This amorphous chalcogenide material has good potential for sensor application in the mid-IR range. Characterized by teams at CNRS and Universite de Rennes 1, along with U de Nantes and U of Pardubice Czech Rep. Also added index of CH3NH3PbI3, as detemined by team at the School of Physics, Peking University, CAS Qingdao, and OKeanos. This material has great light absorption characteristics, making them highly desirable for solar cells.
