The ocular tubes are not equipped with dioptric adjusters, so focus is more consistent. Focusable eyepieces are included to compensate for vision irregularities, and are available in various optional magnifications. Rotating interpupillary adjusters simplify the process of aligning the eyepieces for each user.

Designed for phase contrast observation of cell cultures in transmitted light, these achromat objectives combine field flatness and easy focusing with cost efficiency. They are well suited for routine microscopy demands.

This package includes a powerful 30W LED illuminator with dual fiber-optic goosenecks. The energy-efficient light-source projects bright, daylight-balanced light which is channeled through dual 22″ gooseneck fiber-optic light-guides. This allows you to use two sources of direct lighting from virtually any angle. The flexible, heavy-duty metal-sheathed guides will hold up to heavy use in your workshop, factory, or lab without worry of crimping or breaking. The light-source is equipped with an active cooling system which is much quieter than comparable incandescent illuminators due to the lower heat level generated by LEDs.

Designed for clinical research and routine examination in labs using phase contrast illumination, these achromat objectives offer excellent field flatness.

The SM-4NTP is a heavy-duty, highly-flexible microscope designed for biological and industrial applications. This model is especially popular in the QC, repair and engraving industries thanks to its ease-of-use and reliability. This model features a zoom-lock to maintain consistent magnification when needed, and uses focusable eyepieces rather than integrated dioptric adjusters. With its wide zoom range and double-arm boom-stand, this model will become an indispensable instrument in any workshop or lab. The trinocular photo-port is simul-focal, so it can be used simultaneously with both eyepieces.

Microscope objectives come in a range of designs, including apochromat, semi-apochromat, and achromat, among others. Our expansive collection of microscope objectives suits a wide variety of life science applications and observation methods. Explore our selection below to find a microscope objective that meets your needs.

The ocular lens is located at the top of the eyepiece tube where you position your eye during observation, while the objective lens is located closer to the sample. The ocular lens generally has a low magnification but works in combination with the objective lens to achieve greater magnification power. It magnifies the magnified image already captured by the objective lens. While the ocular lens focuses purely on magnification, the objective lens performs other functions, such as controlling the overall quality and clarity of the microscope image.

This semi-apochromat objective series provides flat images and high transmission up to the near-infrared region of the spectrum. Acquiring sharp, clear images without color shift, they offer the desired quality and performance for fluorescence, brightfield, and Nomarksi DIC observations.

The stereo optics provide clear, sharp images with excellent focus-depth and a large working-distance. With 0.7X-4.5X zoom objectives, moving through the magnification range is as easy as turning a knob. A zoom-lock allows the objectives to be set to a consistent magnification when needed. 10X wide-field eyepieces provide an ample magnification range from 7X to 45X, with high-eyepoint optics to accommodate glasses or goggles. A 2X Barlow lens is included, which can be mounted to the objective housing to double the magnification range to 14X-90X. This will also result in decreased working distance. The combined magnification ranges provide 7X-90X.

The simul-focal optics in this microscope allow the trinocular port to be used simultaneously with both eyepieces. This means a camera can stream live images from the microscope while you continue to work with full stereoscopic vision. This is accomplished by sharing the left objective lens with the left ocular and the photo-port. This microscope uses our CX series trinocular port, so it can be easily replaced with optional C-mount ports to match specific cameras.

This ability to view microscopic images on your computer reduces eye-strain, and allows groups of people to view images at the same time. The USB 3.0 connection provides greater bandwidth for faster frame-rates. A 0.5X reduction lens is included to capture more of the microscope’s field-of-view. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.

Many microscopes have several objective lenses that you can rotate the nosepiece to view the specimen at varying magnification powers. Usually, you will find multiple objective lenses on a microscope, consisting of 1.25X to 150X.

What isobjective lensinmicroscope

To clean a microscope objective lens, first remove the objective lens and place it on a flat surface with the front lens facing up. Use a blower to remove any particles without touching the lens. Then fold a piece of lens paper into a narrow triangular shape. Moisten the pointed end of the paper with small amount of lens cleaner and place it on the lens. Wipe the lens in a spiral cleaning motion starting from the lens’ center to the edge. Check your work for any remaining residue with an eyepiece or loupe. If needed, repeat this wiping process with a new lens paper until the lens is clean. Important: never wipe a dry lens, and avoid using abrasive or lint cloths and facial or lab tissues. Doing so can scratch the lens surface. Find more tips on objective lens cleaning in our blog post, 6 Tips to Properly Clean Immersion Oil off Your Objectives.
