The OSLO software is used by scientists and engineers to design lenses, reflectors, optical instruments, laser collimators, and illumination systems. It is also used for simulation and analysis of optical systems using both geometrical and physical optics. In addition to optical design and analysis, OSLO provides a complete technical software development system including interactive graphics, math, and database libraries.

The OSLO Optics Reference, which can be downloaded as a PDF,[11] provides a self-contained introductory course in optical design.

OSLO has many unique features, for instance slider wheels. This feature allows users to affix up to 32 graphical sliders providing callbacks to default or user-supplied routines that perform evaluation or even full optimization iterations when a slider is moved. Some examples in the use of these slider wheels to design telescopes are provided by Howard.[9]

Objectivelens function

The magnification of the eyepiece is inversely proportional to its length, while the magnification of the objective lens is directly proportional to its length.

Eyepiece: Installed at the upper end of the lens barrel, usually with 2-3 pieces, engraved with symbols of 5 ×, 10 ×, or 15 × to indicate its magnification, usually equipped with a 10 × eyepiece Objective lens: Installed on the rotator at the lower end of the lens barrel, there are usually 3-4 objective lenses, among which the shortest one engraved with the "10 ×" symbol is the low magnification lens, the longer one engraved with the "40 ×" symbol is the high magnification lens, and the longest one engraved with the "100 ×" symbol is the oil lens. In addition, a circle of different colored lines is often added to distinguish between the high magnification lens and the oil lens

OSLO is primarily used in the lens design process to determine the optimal sizes and shapes of the components in optical systems. OSLO has the capability of modeling a wide range of reflective, refractive and diffractive components. In addition, OSLO is used to simulate and analyze the performance of optical systems. OSLO's CCL (Compiled Command Language), which is a subset of the C programming language, can be used to develop specialized optical and lens design software tools for modeling, testing, and tolerancing optical systems.

1. The function of the eyepiece of an optical microscope It is to further enlarge the real image that has been magnified by the objective lens and has a clear resolution, to the extent that the human eye can easily distinguish it.

The objective lens is equivalent to the lens of a projector, and objects are inverted and magnified into a real image through the objective lens; The eyepiece is equivalent to a regular magnifying glass, and the real image formed by the objective lens is then transformed into an upright and magnified virtual image through the eyepiece

OSLO provides an integrated software environment that helps complete contemporary optical design. More than a lens design software, OSLO provides advanced tools for designing medical instrumentation, illuminations systems and telecommunications equipment, to name just a few typical applications. OSLO has been used in a multitude of optical designs including holographic systems,[1] anastigmatic telescopes,[2] gradient index optics,[3] off-axis refractive/diffractive telescopes,[4] the James Webb Space Telescope,[5] aspheric lenses,[6] interferometers,[7] and time-varying designs.[8]

The difference between eyepiece and objective lens in optical microscope The eyepiece and objective of a microscope are both convex lenses, with the difference being that the focal length of the eyepiece is shorter,

2. The relationship between the eyepiece and objective lens of an optical microscope. The objective lens has already distinguished the fine structures clearly. If it is not magnified by the eyepiece, it cannot reach the size that the human eye can distinguish, and then it cannot be seen clearly; However, fine structures that cannot be distinguished by the objective lens cannot be seen clearly even after being magnified by a high-power eyepiece. Therefore, the eyepiece can only serve as a magnifying lens and will not improve the resolution of the microscope. Sometimes, although the objective lens can distinguish two objects that are very close together, the distance between the images of these two objects is smaller than the resolution distance of the eye, so it is still difficult to see clearly. So, the eyepiece and objective lens are both interrelated and mutually restrictive.

Optics Software for Layout and Optimization (OSLO) is an optical design program originally developed at the University of Rochester in the 1970s. The first commercial version was produced in 1976 by Sinclair Optics. Since then, OSLO has been rewritten several times as computer technology has advanced. In 1993, Sinclair Optics acquired the GENII program for optical design, and many of the features of GENII are now included in OSLO. Lambda Research Corporation (Littleton MA) purchased the program from Sinclair Optics in 2001.

OSLO works with other software products using a DDE (Dynamic Data Exchange) Client/Server interface. This enables the program to work with products such as MATLAB to create a multi-disciplinary environment, such an environment was used to design and analyze the Thirty Meter Telescope (TMT).[10]
