Abstract

We demonstrate new GRIN-based endomicroscopic objectives for high resolution single photon fluorescence imaging modalities. Two endoscopic optical design approaches are presented in detail utilizing firstly diffractive and secondly refractive optical elements for the color correction in a spectral range from 488 nm to 550 nm. They are compared with their precursor device experimentally and by simulation. Inherent aberrations for off-axis field points could be lowered remarkably compared with the values of the state-of-the-art system by increasing the intrinsic optical complexity but maintaining the outer spatial dimensions. As a result, those presented objectives predict a diffraction-limited imaging of objects up to 300 μm in diameter with a numerical aperture of 0.8 while keeping an overall outer diameter of the assembly at 1.4 mm. Lastly, confocal fluorescence imaging experiments focus on the comparison between the numerical predicted and the practically achieved quality parameters.

Fig. 3 Evaluation of the influence of the undesired diffraction orders of the DOE on the imaging performance for confocal single photon fluorescence imaging processes; The calculation is performed by convolving the PSF in the object plane (λ =488 nm) with the PSF in the image plane (λ =550 nm) while assuming a complete conversion of the energy at the specimen; The table on the left presents the ratio between the detected (EDetected) and emitted amount of energy (EEmitted) passing through the on-axis pinhole in the image plane of the size of one airy diameter (2.2 μm; @λ =550 nm); the DOE is assumed to work perfectly in either the zeroth, first or second diffraction order for the illumination and detection for case (a); the DOE is assumed to work perfectly in the first order for the illumination and perfectly in either the zeroth, first or second diffraction order for the detection in case (b) (η0/1/2 is the diffraction efficiency of the corresponding order).
