Compound microscopes use two lenses to magnify a specimen—an ocular lens and an objective lens. The ocular lens commonly magnifies. 10 times (10×). The three ...

This product consists of two panes of tempered glass separated by a spacer. The space between the two panes of glass is filled with air, which provide insulation. These are most often used in residential window applications.

Long-working distance objectives are made so you can see specimens even when they are farther away than usual. This is usually needed when a sample is stuck in a thick slide or is under a thick glass plate.

Microscope lenses come in different types that vary based on the magnification’s power. Here are the types of microscope objective lenses.

A reflected darkfield objective works for darkfield microscopy. This technique produces a dark background with a strong contrast to aid in the visibility of translucent specimens. This object is designed to observe samples not dropped inside a covered slide. Reflected darkfield objectives typically have signs like BD, Neo, or BF/DF to help you identify them.

Phase contrast microscopy makes translucent specimens easier to see by making the difference between the background and the foreground stronger. In a phase contrast objective, a black ring around the lens is used to control and translate changes in the phase of light rays into changes in their amplitude. In addition, the way the light rays are bent and focused gives the image seen through the eyepiece a lot of contrast.

Low-E glass helps deliver year round comfort and energy savings. In the winter, it reflects heat back into the room. In the summer, it rejects the sun’s heat and UV rays.

Insulating Glass Units (IG Units) can be made with air or other gases between the two sheets of glass. We use air-filled because the seals have a longer life with air. While we can provide Argon gas filled windows at an increased price, we caution that this could result in reduced life due to seal failure.

There are several benefits associated with dual pane windows. The most well-known is energy savings, as they are the most common type of energy-efficient residential insulated windows on the market today. Originally intended to protect homes from extreme weather conditions, other benefits have been convincing people to install them with increasing frequency.

These are custom manufactured dual pane window units, meant to replace existing windows in your home. You can select glass pane thickness and overall sealed window unit thickness. These can be purchased with or without the white grid between the panes.

The simplest types of microscopes are magnifying glasses with a single convex lens (meaning both sides are curved outward). This kind of lens usually makes items look 5–10 times bigger by changing how the light gets into the human eye. Compound microscopes are used in schools, homes, and professional labs. They have at least two lenses that work together to magnify an image.

Microscope objective lenses work by changing how light goes through them. Essentially, when light shines on an object underneath a microscope, this light travels through the lens and bends toward your eyes, which makes the object bigger than it is. Remember that magnification power varies based on the type of lens and microscope, with magnification reaching 1000x and above. You can also find specialized objective lenses for advanced experiments.

Utilizing this microscope objective lens is pretty simple. Firstly, you need to adjust the scanning lens to properly focus and center the specimen. Afterward, you need to turn the objective turret clockwise to face the low magnification lens. Lastly, re-center your specimen after you’ve fine-tuned the focus with the coarse focus knob.

This type of lens is usually used for smaller specimens, such as cells and bacteria, which cannot be seen with just the human eye. This includes molds, tardigrades, germs, and others.

Microscope lenses are pieces of glass that work in a microscope to aid magnification. Based on the lens type and power, you can magnify a specimen by up to 200x or more. How these tools work is straightforward, and this article will cover everything you need to know about them.

Due to the difference between the glass slide and the refractive indices of air, a specific oil is required to help fill the space. Without this oil, the objective lens won’t function correctly. Hence, you won’t get the appropriate magnification and resolution, leaving you with too much distortion.

To accurately measure you will likely need to temporarily remove your existing window. Measure the outside dimensions (height and width) of the sealed window unit to the nearest 1/16”. Measure the dual pane overall thickness. This will typically be ½”, 5/8”, ¾”, 7/8” or 1”. You may attach a custom drawing, pattern or sketch or any special comments about your order.

Using us ensures that you will never miss closing a deal as a result of a broken unit. Our window units ship in days and not weeks.

Capillary tubes are used in insulated glass in order to equalize pressure between the inside and the outside of the unit. During transit the insulated unit can travel the a variety of altitudes and the unequal pressure can weaken the seals, therefore shortening the life of the insulated unit. These tubes are to be removed prior to install and to be sealed with a silicon based sealant.

The following combination of glass tints are available: Clear / Clear, Low-E / Clear, Solex / Clear, Light Gray / Clear, Bronze / Clear, P516 / Clear, Bronze / Low-E, P516 / Low-E, Light Gray / Low-E, Solex / Low-E, Rain / Clear, Clear Tempered / Laminate, Dark Gray / Clear, Solar Cool Bronze / Clear, Satin Etch / Clear.

The numerical aperture (NA) of an optical system (e.g. an imaging system) is a measure for its angular acceptance for incoming light.

Yes, options include ⅝” grid or a decorative 1” sculptured grid are available. Colors include: White, Tan, Champaign, Dark Bronze and Aluminum. You can also specify the grid pattern.

An optical microscope comes with lenses that change how rays of light travel through them. When light bounces off an object under a microscope and goes through the lens, it deflects toward the eye. This makes the item seem bigger than it is.

This lens, in conjunction with the eyepiece lens, will provide the smallest magnification possible. For example, a microscope with a 10x eyepiece lens and a 4x objective lens will have a magnification factor of 40x. The magnification you get from this lens is similar to what you would from a stereo microscope, allowing you to study specimens like leaves and feathers. Also, the lens has a red band that encircles the housing of the lens. Scanning object lenses have low power and are typically used to scan a specimen before using higher magnifications.

The use of differential interference contrast (DIC) lenses in brightfield microscopy helps to visualize transparent samples better. By providing contrast without the need for staining, DIC objectives reduce the amount of staining performed. In most cases, a DIC lens will not be present on a compound microscope for school or home use.
