Computationally efficient performance simulations for a thirty-meter telescope (TMT) point design

A construction in which a light emitting/receiving element and an optical fiber are optically coupled by a lens system formed by a biconvex aspherical lens. This lens is featured by: a first lens surface (R1) and a second lens surface (R2) both having a positive refracting power. At least one lens surface is formed by an aspherical surface. A distance L between the light emitting portion and the light receiving portion is 1.3129 mmLens thickness t at its center is 0.2147 mmfocal length of the lens, and phi =incident pupil diameter.
