“…Ray tracing simulations are widely used to design, optimize and analyze optical systems. Its applications are diverse, ranging from designing spectrometers (Naeem et al, 2022) or telescopes (Zhang et al, 2023), to understanding the optics of the human eye (Hong et al, 2011;Simpson, 2020;van Vught et al, 2022). Moreover, in ophthalmology, ray tracing is used to optimize the outcomes of cataract surgery (Artal et al, 2023;Canovas & Artal, 2011) and evaluate the accuracy of ocular radiotherapy (Jaarsma-Coes et al, 2023).…”

Zemax OpticStudio (Ansys, Inc) is a commonly used software package for designing optical setups and performing ray tracing simulations. It offers an Application Programming Interface (API) but interacting with this API is complex. Consequently, current ray tracing simulations generally require substantial manual user interaction, which in turn hampers the sharing of methods between scientists. We have therefore developed ZOSPy, a Python package that provides an accessible interface as well as unit tests. As a result, ZOSPy enables scientists to focus more on optical modelling instead of coding and contributes to open science as optical setups and analyses can easily be shared amongst users.

This article presents a comprehensive investigation into the intensity‐phase characteristics of ultrashort laser pulses propagated through a 10 mm thick polymethyl methacrylate (PMMA) using frequency‐resolved optical gating (FROG) and cross‐correlation frequency‐resolved optical gating (XFROG) techniques. The study focuses on discerning characteristic changes that are induced by the PMMA on the laser pulse. The results reveal that the phase variations exhibit a consistent trend and pattern. At the same time, the temporal full width at half maximum (FWHM) of both FROG and XFROG measurements displays only minor changes. The overall analysis indicates that PMMA induces no discernible modifications in the pulse, thus positioning it as a viable optical element. The analysis of reference FROG, FROG, and XFROG with PMMA is compared and discussed, showing that this analysis provides a foundation for optimizing PMMA's utilization in the optical components of ultrafast laser systems. This experimental study strongly affirms that PMMA could be a potential candidate as an optical element for laser pulses.

“…When the image plane tilt is set, the plus lens and the minus lens could have lower curvature and focal power. And according to the aberration expressions (15) to (19), lower focal power means lower spherical aberration, coma, astigmatism and field curvature, which is preferable for large aperture lens design.…”

“…In these applications, the target spectral signal is often very faint and can easily be overwhelmed by background signals. As a result, detectors such as CCDs, CMOS sensors, and InGaAs arrays must exhibit high sensitivity and typically require long integration times [14][15][16]. These factors limit the performance of fiber optic spectrometers.…”

The numerical aperture of the spectrometer is crucial for weak signal detection. The transmission lens-based configuration has more optimization variations, and the grating can work approximately in the Littrow condition; thus, it is easier to acquire high numerical aperture (NA). However, designing a large aperture focusing lens remains challenging, and thus, ultra-high NA spectrometers are still difficult to acquire. In this paper, we propose a method of setting image plane tilt ahead directly when designing the large aperture focusing lens to simplify the high NA spectrometer design. By analyzing the accurate demands of the focusing lens, it can be concluded that a focusing lens with image plane tilt has much weaker demand for achromatism, and other monochromatic aberration can also be reduced, which is helpful to increase the NA. An NA0.5 fiber optic spectrometer design is given to demonstrate the proposed method. The design results show that the NA can achieve 0.5 using four lenses of two materials, and the MTF is higher than 0.5 when the spectral dispersion length is 12.5 mm and the pixel size is 25 μm, and thus, the spectral resolution can achieve 6.5 nm when the spectral sampling ratio is 2:1. The proposed method can provide reference for applications when appropriate materials are limited and high sensitivity is necessary.
