Andrew M. Weiner is the Scifres Family Distinguished Professor of Electrical and Computer Engineering at Purdue University. Professor Weiner is the coeditor of two conference proceedings and has published six book chapters, over 200 journal articles, and over 350 conference papers. His research focuses on ultrafast optical signal processing, high-speed optical communications, and ultrabroadband radio-frequency photonics. He is especially well known for pioneering the field of femtosecond pulse shaping, for which he has received numerous awards.

This book fills the need for a thorough and detailed account of ultrafast optics. Written by one of the most preeminent researchers in the field, it sheds new light on technology that has already had a revolutionary impact on precision frequency metrology, high-speed electrical testing, biomedical imaging, and in revealing the initial steps in chemical reactions.

Avantier continues to redefine precision microscopy with its cutting-edge NIR, NUV, and UV infinity corrected objectives. Engineered for accuracy and clarity, these objectives elevate research and analysis across near-infrared (NIR), near-ultraviolet (NUV), and ultraviolet (UV) spectra. With advanced optical coatings, aberration correction, and infinity-corrected designs, researchers can explore samples with unmatched clarity and fidelity. These objectives are pivotal for applications ranging from material science to life sciences, enabling scientists to delve deeper into the microscopic world with confidence. Avantier offers a wide variety of microscopes, each equipped  with  multiple objective lenses that can be rotated to view specimens at varying magnification powers. Demonstrating its commitment to excellence, Avantier delivers tools that empower scientific discovery and innovation.

While a microscope comprises numerous parts, the objective lens arguably serves as its cornerstone. The resolving power, total magnification, and ultimate image quality of a microscope hinge largely on the chosen objective lens.

Types ofobjective lenses

A microscope objective lens produces a real, magnified image of an object placed within its field of view. The image is then further magnified by the ocular lens (eyepiece) before being observed. At Avantier, we offer in-stock microscope objective lenses, readily available for immediate use in a variety of applications. For unique or specialized requirements, we offer custom solutions for multiple objective lenses.

Avantier, a premier manufacturer of high performance microscope objective lenses, produces a wide range of quality microscope objectives for diverse applications, including research, industry, forensics, and medical diagnostics. We carry many types of objectives in stock, including apochromatic, achromatic,  and semi-apochromatic. We can also produce custom objectives tailored to perform optimally within your specific spectral range, ensuring the highest level of imaging precision for your application.

Ultrafast Optics begins with a summary of ultrashort laser pulses and their practical applications in a range of real-world settings. Next, it reviews important background material, including an introduction to Fourier series and Fourier transforms, and goes on to cover:

Objectives are designed to magnify an object by a specific factor, ranging from 4x (a scanning objective) to 40x (a high-power objective), and even up to 100x for an oil immersion lens. To maximize flexibility, microscopes are often equipped with up to four objectives mounted on a rotating nosepiece or turret. In the case of an infinity-corrected objective lens, the magnification is calculated by dividing the reference focal length by the objective’s focal length.

The microscope’s total magnification can be calculated by multiplying the magnification power of the eyepiece by that of the objective lens. For example, viewing an object through a 10x eyepiece and a 4x objective results in a 40x magnified image.
