Abstract
An optical system including a transparent fluid and a container filled with the fluid as well as at least one optical element having an index of refraction which approximately matches that of the fluid. The fluid is chosen to have a viscosity no greater than 40 centistokes. As a result, the low viscosity of this optical fluid reduces thermal irregularities. Also, improved transmission, particularly in the blue spectrum is achieved as compared to conventional optical fluids.
