The standard compound light microscope has 3 objective lenses to provide different magnification powers, resolving abilities, and fields of view to visualize specimens in increasing detail.

Phase contrast and fluorescence microscopy require specialized objectives with matched condenser optics to image transparent specimens. These are often incorporated as a fourth objective or replace one of the standard ones.

While the basic 3 objective arrangement still dominates today, some microscopes incorporate additional objectives or special enhancements for increased performance and capabilities.

The set of 3 objective lenses on most compound microscopes elegantly fulfills the range of observational needs in microscopy, from scanning the big picture to examining the most minute details. Their differing optical properties and fields of view provide efficient and flexible viewing capabilities not possible with a single objective lens. The specific numbers and powers may be tailored for particular applications, but the core triad arrangement remains ubiquitous out of logical necessity.

Our milling and grinding process consistently upholds a superior level of product quality by achieving precise shapes, tight tolerances, and smooth surface finishes in accordance with rigorous standards. The automated procedures effectively minimize defects, thereby enhancing overall product quality. This ensures the production of optical components tailored for applications where precision is of utmost importance in the field of optics.

Having a continuum of magnifications allows the microscope to accommodate samples of vastly different sizes from whole insect bodies down to single cells. A single high-power objective cannot cover this entire range.

The level of microscope magnification depends on the optical properties of both the ocular and objective lenses. The ocular lens magnifies the primary image 10x. The objectives provide progressively higher magnifying power of 4x, 10x, 40x, and sometimes 100x.

The provision of 3 objective lenses with differing optical properties confers important complementary advantages that enhance the microscopy user experience and workflow efficiency.

Lenses with lower power and larger fields of view can have optics optimized for brightness whereas high magnification lenses with narrow fields are optimized for resolution at the expense of brightness.

Higher magnification requires higher resolution to realize the full benefit. The higher-powered objectives have correspondingly greater resolving power to take advantage of the increased magnification whereas the lower-power lenses have comparatively less resolution which is ample for their magnification level.

The compound light microscope is an indispensable tool used ubiquitously in science disciplines to visualize small objects in fine detail. Unlike simple magnifying glasses, the compound microscope uses two lens systems to enlarge specimens up to 1000x their actual size.

With advanced features like Synchrospeed, Variospeed modes, and ADAPT technology, it ensures precision in producing customer aspheres and freeform optics.

High-performance objectives may have adjustable correction collars to optimize the optical correction for viewing specimen slides with different coverslip thicknesses, allowing the best possible image.

Avantier’s in-house KERN EVO CNC machining center is the epitome of optimal productivity. With rapid acceleration, high feed rates, and spindle speeds of up to 50,000 RPM, it guarantees unparalleled precision and delivers outstanding surface finishes for lenses, mirrors, filters, and windows.

The range of magnifications enables users to choose the appropriate level for their particular application, whether surveying tissue architecture or examining subcellular organelles. No single objective lens can provide optimal performance across this wide range of viewing needs.

Our lens grinding and polishing process is a multi-step journey towards perfection. It commences with manual abrasive rough grinding, followed by high-speed fine grinding for meticulous shaping and smoothing. We conduct regular thickness checks to maintain defined tolerances. Traditional pitch precision polishing and CAD/CAM-integrated high-speed precision polishing ensure exceptional surface accuracy and reduced irregularities. Every lens is meticulously inspected using our in-house metrology tools, such as interferometers, spectrophotometers, and micrometers, guaranteeing precision, optimal performance, and top-notch quality.

Certain instruments are designed to accommodate additional high-power 60x or 100x objective lenses when extremely high magnification and resolution are critical, such as for cytology or microbiology applications.

Avantier specializes in the process that involves applying thin films to optical components, enhancing light transmission, modifying reflection, or manipulating polarization.

Cutting-edge technologies like IAD E-Beam, IBS, PARMS, and APS are employed in the production of these coatings.

The 40x or 100x high power objective produces the highest magnification and resolution to reveal subcellular structures and other intricate details not discernable with the lower powered lenses but has an extremely narrow field of view. It is used for critical inspection of key areas after initial surveys with lower-powered objectives.

The multiple objectives with parcentered optics allow users to quickly switch between lenses and magnifications to obtain just the right view. This facilitates efficient and intuitive workflows.

The major components of a compound microscope are the ocular lens in the eyepiece, the objective turret housing multiple objective lenses, the condenser lens below the stage, the illumination system, and the mechanical arm. Each part plays a critical optical or functional role.

The lowest magnification objective is typically a 4x or 10x lens. Its primary purpose is to provide a wide field of view of the overall specimen on the slide for initial orientation and scanning. The low magnification reduces aberrations from optical imperfections.

The 10x or 20x medium power objective delivers comfortable viewing magnification and reasonably high resolution to see some finer details in the context of the larger specimen structure. It is commonly used for routine examination, counting cells, measuring proportions, and making sketches.
