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.

Standard single-wide retarder/proofers come with a field-reversible door that can be hinged on the right or left and switched on site to accommodate workflow. Our double-wide retarder/proofer has all the standard features, plus doors that swing from the outside corners and have a lap strip where they meet in the center—no center jamb to obstruct or limit loading.

Retarder meaning

The patented airflow and humidity systems of the Baxter Standard Retarder/Proofer ensure careful proofing of delicate products. Our airflow system forces air through the retarder/proofer in two different directions, creating a circular pattern of heat for a balanced, controlled proof that minimizes product drying. Our humidification system creates abundant moisture using a nozzle to spray water onto a heated metal plate. Temperature and moisture levels are also controlled during the retarding cycles to eliminate drying before the proof cycle begins.

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.

Objective lenses are responsible for primary image formation, determining the quality of the image produced and controlling the total magnification and resolution. They can vary greatly in design and quality.

MXPLFLN objectives add depth to the MPLFLN series for epi-illumination imaging by offering a simultaneously improved numerical aperture and working distance.

Olympus microscope objective lenses for industrial inspections offer outstanding optical performance from the visible light to near-infrared region. At Evident, we offer an extensive selection of Olympus objectives suited to specific inspection requirements and tasks. Our MXPLFLN-BD objective is designed for darkfield observation and examining scratches on polished surfaces, while our SLMPLN objective is ideal for electronic assembly inspection. Find your ideal microscope objective today for your inspection task. No matter your requirements, Olympus objective lenses have you covered.

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

Our retarder/proofer has door-mounted, eye-level digital controls to let you precisely set temperature and humidity for the proofing cycle as well as set the retarding temperature to meet the requirements of your product. What’s more, a programmable 24-hour timer allows programming of both retarding and proofing cycle settings up to one week in advance.

The Baxter Retarder/Proofer is an excellent way to maximize square footage for small bakeries, large supermarkets or institutions.

We know that your operation is just as variable as the products you need to proof. That’s why every retarder/proofer width we offer, single or double, is available in five depths to accommodate larger foodservice operations and smaller bakeries. The versatility doesn’t end there. We include four independent rack timers, so you can simultaneously proof products that require varying times at once. A programmable 24-hour timer can be set to a one- or seven-day cycle.
