X Line Extended Apochromat Objectives

X Line™ extended apochromat objectives are high-performance lenses that offer simultaneously enhanced brightness, resolution, uniformity, and color with our most advanced lens technology. Our award-winning X Line UPLXAPO series enables consistent quality across applications, from brightfield and fluorescence to confocal and super-resolution microscopy. These lenses are corrected for four wavelengths, exceeding the standard three-wavelength correction of conventional apochromats for sharper images with accurate color across an industry-leading spectral range of 400–1000 nm. Whether used in pathology, laboratory diagnostics, high-end research, or whole slide imaging, X Line objectives help ensure optimal image quality from the center to the edge of the field of view.

Apochromat Objectives

Apochromatic objectives are high-performance lenses designed to bring three wavelengths of light into sharp focus at the same point. This advanced color correction improves clarity and contrast, making these lenses ideal for applications requiring precise detail and color, such as fluorescence microscopy and differential interference contrast (DIC) observation. Our apochromatic objective range includes high-performance A Line series options tailored to applications such as TIRF and super-resolution imaging. It also features our MPLAPON plan apochromat series, which offers superior chromatic correction and resolution with high wavefront aberration correction for non cover glass applications.

Semi-Apochromat (Fluorite) Objectives

A semi-apochromatic objective lens, also known as a fluorite lens, offers improved color correction compared to standard achromats but does not reach the full performance of an apochromat. These lenses typically correct for two wavelengths completely and partially correct a third, reducing chromatic aberration and improving image sharpness at a lower cost. Semi-apochromats are practical for routine imaging where higher clarity is needed without the full precision of an apochromat. They are commonly used in routine brightfield, darkfield, phase contrast, and fluorescence imaging and have options for long working distance and super long working distance.

Achromat Objectives

Achromat objectives are lenses designed to correct chromatic aberration for two wavelengths of light, and spherical aberration for one wavelength. This correction supports clear, reliable imaging for routine applications in biology, materials science, electronics inspection, pathology, and education. The most common type of objective lens, achromats provide high-quality observation for many standard laboratory and assembly tasks. Our wide selection of achromats includes lenses for various routine observation needs, from brightfield and darkfield to polarized light and fluorescence microscopy.

Water Immersion Objectives

Water immersion objectives are lenses designed to use water as the immersion medium between the coverslip and the front lens or to be dipped into water. They enable high numerical aperture imaging of live cells, thick tissues, and even whole animals. Water as the immersion medium helps with reduced spherical aberration, as the refractive index of water (1.33) is close to that of biological specimens. These properties make water immersion objectives widely used for high-resolution and high-contrast imaging in confocal microscopy, as well as live-cell imaging and long-term experiments.

Silicone Immersion Objectives

Silicone immersion objectives use silicone oil between the lens and the sample, offering a refractive index of 1.40—closely matching that of live cells and tissues. This reduces optical distortion, especially when imaging deeper into biological specimens. Compared to water immersion lenses, silicone objectives deliver higher resolution, improving the accuracy of cell and tissue morphology studies. The silicone medium is also highly stable, with no evaporation compared to water or glycerol, making it ideal for long-term, live-cell imaging and time-lapse applications. Our A Line™ super apochromatic objectives use silicone oil to provide clear, high-contrast images in advanced research, including multi-color and spectral imaging. These lenses are corrected for four wavelengths, surpassing the standard three-wavelength correction of conventional apochromats for sharper, more accurate imaging across a broader light spectrum.

Multiphoton (MPE) Objectives

Multiphoton objectives are high-performance lenses designed for multiphoton excitation (MPE) microscopy, a powerful fluorescence imaging technique that uses long-wavelength laser light to excite fluorescent markers deep within a specimen. These objectives are engineered to transmit near-infrared light efficiently and to collect faint fluorescence signals with high sensitivity. Their optical design often includes a large numerical aperture for improved resolution and brightness, as well as a long working distance to accommodate thick or irregular samples.

Total Internal Reflection Fluorescence (TIRF) Objectives

A TIRF objective is a specialized high numerical aperture lens designed for total internal reflection fluorescence (TIRF) microscopy. It focuses light at a very shallow angle to create an evanescent field that excites fluorescent molecules only within a thin region, typically less than 200 nm, at the sample surface. This selective illumination produces exceptionally clear images of events occurring at or near the cell membrane, making TIRF objectives ideal for studying processes such as protein interactions, membrane dynamics, and cell adhesion.

White Light Interferometric (WLI) Objectives

White light interferometric (WLI) objectives are specialized lenses used to measure surfaces with high precision, down to just a few nanometers. They use noncontact white light to create interference patterns that reveal fine details in structures. This makes them ideal for checking the quality of fine patterns, surface roughness, or even transparent materials. Commonly used in precision engineering and manufacturing, these lenses help ensure products meet strict quality standards. Our Mirau-type objective designs set the standard in WLI, combining a high numerical aperture with a wide field of view to enhance efficiency and accelerate results.

IR Objectives for Silicon and Glass Materials

Infrared (IR) objectives are specially designed lenses used to image through glass and silicon (Si), enabling nondestructive inspection of micro-electromechanical systems (MEMS), electronic components, and semiconductor wafers. These optics can be used with a transmitted-light IR microscope to examine chip damage, short circuits, residue, and other critical structures below silicon or glass layers. Our LMPLN-IR and LCPLN-IR long working distance plan achromat lenses are developed for optimal transmission in the 700-1300 nm wavelength range, enabling bright, high-contrast imaging for inspection.

Phase Contrast Objectives

Phase contrast objectives are lenses designed for phase contrast microscopy, a technique that enhances the visibility of transparent specimens, such as live cells, without staining or altering them. These objectives contain a built-in phase plate that works with a matching phase contrast condenser. Together, they transform subtle differences in the way light passes through a specimen into visible contrast. The result: fine details in unstained samples become easier to see in real time.

Relief Contrast Objectives

Relief contrast objectives, also known as Hoffman modulation contrast objectives, are lenses designed for relief contrast microscopy, a technique that enhances the visibility of transparent, unstained specimens, particularly when using plastic culture vessels. They feature a special optical design that works with a matching relief contrast condenser to produce images with a pseudo 3D effect. This makes fine details stand out, even in samples like oocytes, with very little natural contrast, while avoiding many of the optical issues that can occur when imaging through plastic.
