Other people in the room may need the lights on and this is acceptable. If you need to keep the sample dark, put the Evos supplied box over the sample or put black cloth or cardboard over sample. One of the selling points of the Evos is the ability to use in a fully lighted room. Images from thicker bottom dishes may look ok at 10X and 4X, but lenses really designed for #1.5 coverslips. Instrument calibrated for samples that have coverslips on them. Want to read the whole manual? Here it is. environmental chamber with heat and CO2 control for extended live imaging.By request: YFP and near infra-red (Cy5).Standard fluorescence: violet/blue, green, red.It may be used for live imaging and for fixed samples.

It can tile large areas, has Z series, and may repeatably image multiple positions. It can be used for chromogenic histology. The lenses are not the best, but it is designed to be easy to use and give decent images with minimal microscopy expertise. The primary purpose of this microscope is screening cells in dishes. This microscope is for widefield fluorescence, simple brightfield, and phase contrast. Additional timelapse Instructions click here

Must use Safari, Chrome, or Firefox not Explorer Enter 25.4 for the Known Distance, km for the Units of Length, and click OK.Signup to use microscope. To select the distance between the two islands. This slice is labeled 2/2 in the image window status bar.

Use the arrow keys on your keyboard to flip to slice 2 of the stack.

One reason for stacking the two images is that setting the scale for one image in a stack automatically sets the scale for the others. Now you'll set the scale on these images using the distance you measured between the two islands. Since you are working with a stack, check the Stack Position option, then click OK.

In the Set Measurements dialog box, check the Area and Perimeter (length) options.

You'll also need to measure straight line distances when setting the scale. You are interested in measuring the surface area of the lake. Elsewhere, new islands have appeared, creating new habitat for some animals. Some islands are now connected to the shore, making once-safe habitat more accessible to predators. It is now much more difficult for people to launch boats and for fish to survive in the shallower water. The lake is noticeably smaller and you can see the "bathtub ring".

Create a stack To combine the two images into a stack, choose Image > Stacks > Images to Stack.

(You'll learn a lot more about stacks in Week 3!) In addition to flipping through images, you can also animate them. Stacking images is a useful way to look at images that show change over time. In ImageJ a window containing multiple images is called a stack, and the individual images are called slices.

To make an initial side-by-side comparison of the two images, choose Window > Tile.Īnother way to compare the images is to display both images in the same window and flip back and forth between them.

Slight color differences between the two images are mostly due to differences in atmospheric conditions on the two dates. These true color satellite images show the exact same view of Lake Mead, four years apart. , choose File > Open, navigate to your Week 2 folder, and open the lake_mead_2000.tif image.

If you downloaded this image in the Getting to Know Measuring in ImageJ section, you won't need to download it again.

Download the image below by right-clicking (Win) or control-clicking (Mac) on the link and saving the linked file to your Week 2 directory or folder.You're going to use a pair of high resolution Landsat images one taken in May 2000 and the other in May 2004 to measure changes in the surface area of the lake. To get a real sense of how the water level of Lake Mead has changed in recent years, and what this means in terms of the volume of water lost, we need to view the lake from two different perspectives from above to get a sense of the change in surface area, and from the ground to measure the change in elevation (depth). As of January 2010, the lake was at only 44% of capacity. As the water level drops, the volume of the lake decreases dramatically.

Lakes are 3-dimensional features kind of like upside-down mountains.
