Claim Text:
1. An adjustable total internal reflectance microscopy (TIRFM) illuminator apparatus, the apparatus comprising: an objective lens wherein the objective lens comprises: at least one optical fiber, wherein the at least one optical fiber is adaptable to transmit at least one optical excitation light wavelength through the outer circumference of the objective lens; at least one fiber axial translator for focusing the at least one optical excitation light wavelength, wherein the at least one fiber axial translator is mechanically adjustable in at least one-degree-of freedom; at least one collimating optical element connectable to the at least optical fiber for impinging the at least one optical excitation light wavelength on to the optical axis wherein the at least one collimating optical element comprises at least one optical prism adaptable to impinge the at least one optical excitation light wavelength on to the optical axis through the outer circumference of the objective lens; wherein the objective lens is adaptable to transmit emission light wavelength through the inner circumference of the objective lens; and said TIRFM illuminator apparatus not including a dichroic mirror for impinging the at least one optical excitation light wavelength on to the optical axis.
