Custom-designed F-theta objective lens used in “Optical-resolution parallel ultraviolet photoacoustic microscopy” [North Plainfield, New Jersey] – February 4th, 2025 – Avantier Inc. is pleased to announce that our custom-designed F-theta objective lens has been featured in a pioneering study on parallel ultraviolet photoacoustic microscopy (PUV-PAM) for rapid, slide-free imaging of tissues with irregular surfaces. The […]
Reflective optics are the optics of mirrors: smooth reflective surfaces that change the direction of a wavefront. Reflective optics are key to many industrial and life science applications, as well as astronomy and high-energy physics; they provide a simpler, more affordable option when contrasted with refractive systems.
The diffraction limit is a fundamental constraint on optical systems, defining the maximum achievable resolution due to light diffraction. Ignoring it leads to unrealistic performance expectations in imaging systems.
Confused about geometric optics vs wave optics and how they work together? This article explains what they involve and when to use which.
A Powell lens is a cylindrical lens with an aspherical surface used to shape laser beams into straight, uniformly illuminated lines. It redistributes a Gaussian beam intensity, eliminating central “hot spots” and producing consistent, flat-top light.
An infrared objective lens is an objective lens suitable for the infrared wavelength. The infrared wavelength refers to the three wavelengths of 1-3um, 3-5um and 8-14um, also known as the three atmospheric windows.
Discover the key considerations and design specifications for off-axis parabolic mirrors in high-performance optical systems.
Microscope objective lenses are vital optical elements in microscopy; they collect and focus light from a specimen to form a magnified image. Performance is defined by magnification, numerical aperture, and aberration correction, enabling high-resolution imaging for scientific and industrial applications.
One of the most important features of aspheric lenses is their ability to correct for spherical aberration. Spherical aberration is found in all spherical lenses, such as plano-convex or double-convex lens shapes.
