Howdoesthe eyepiece compare to theobjective lens

A microscope objective lens produces a real, magnified image of an object placed within the field of view. Before it is observed the image is then magnified again by the ocular lens, also known as the eyepiece.

We carry may types of objectives in stock, including apochromat objectives, achromatic objectives,  and semi apochromat objectives.  We can also produce custom objectives designed to work as desired in your target spectral range.

From shafting and supports, to round and square rail guides, linear motion systems to pillow blocks, Thomson demonstrates how our products excel as the best solution in a wide array of industrial applications.

Whatare the 3objectivelenseson a microscope

The ultimate magnification power of a microscope can be calculated by multiplying the magnification power of the eyepiece by that of the objective lens. If an object is viewed through a 10x eyepiece and a 4x objective, the image produced will have been magnified 40x.

“Standardizing encoder availability is a great leap forward in what machine designers can do with an SMLA platform. They have more flexibility in designing applications that require advanced data gathering and analysis and, given the SMLAs’ immediate availability, can get the units into production faster,” said Katona.

DOWNERS GROVE, IL ̶ Thomson Industries, Inc., a leading manufacturer of linear motion control solutions, has announced the availability of a rotating-nut stepper motor linear actuator (SMLA) with a rotary encoder as a standard option. Machine designers with applications requiring positional feedback can now specify the full line of SMLAs integrated with this enhancement.

SMLAs with pre-installed rotary encoders are available now in all NEMA motor frame sizes and leadscrew thread forms listed in the Thomson product catalog. The SMLA online selector tool, which will soon be updated with encoders, can be found at www.thomsonlinear.com/mls.

As machine designers are developing more complex applications requiring monitoring for speed, distance and position, the integration of encoders has been the most requested SMLA customization for Thomson. This strong demand led the company to offer encoders as a standard option for all three SMLA configurations.

Thomson currently has two account systems - one for the website and CAD model downloads, and one for e-commerce. We understand that two logins is an inconvenience and are working to consolidate our systems into one login process. Until we’re able to consolidate the two logins, please follow these guidelines:

Types ofobjectivelenses

Thomson SMLAs use a stepper motor and lead screw shaft to translate rotary motion to linear motion for all three configurations: linear actuator, rotating screw and rotating nut. Previously, designers requiring positional monitoring on either the actuator or rotating screw configurations had to request a custom encoder assembly. A custom option for adding an encoder to the rotating-nut configuration did not even exist.

Objective lens microscopefunction

While a microscope is built of many parts, the cornerstone is in many ways the objective lens. The resolving power and total magnification power of the microscope as well as the quality of the final image all depend on the objective lens used.

Avantier is a premier manufacturer of high performance microscope objective lenses, and we produce a wide range of quality microscope objectives for applications ranging from research to industry to forensics and medical diagnostics. We carry may types of objectives in stock, including apochromat objectives, achromatic objectives,  and semi apochromat objectives.  We can also produce custom objectives designed to work as desired in your target spectral range.

“We are pleased to announce that Thomson customers who want to get precise positional measurement from a rotating-nut SMLA can now specify it as a standard add-on. This addition rounds out the full line as we also offer encoder integration as a standard option for our rotating screw and linear actuator configurations,” said Lindsey Brimage, Senior Product Manager – Lead Screws for Thomson.

Objectives are designed to magnify an object by a certain coefficient; from 4x (a scanning objective) to 40x (a high power objective) up to 100x for an oil immersion lens. For ultimate flexibility, a microscope is often equipped with up to four objectives on a rotating nosepiece or turret.  If an objective lens has infinity-correction the magnification is equal to the reference focal length divided by the focal length of the objective.
