  Information

We offer seven microscopes for doing semen analysis. See a brief description of the differences between our microscopes.

We carry a binocular microscope, a digital microscope, and three styles of monocular microscopes. Kokopelli Technologies microscopes are solidly constructed, high quality microscopes. Most feature cool illumination and separate coarse and fine focus adjustments. Our microscopes are calibrated so you can easily convert the number of sperm you see in the field of view to Million Sperm/mL. The instructions explain use in detail.
We also sell cameras and mechanical slide holders for your microscope.

To help you decide we offer a table comparing the features of each microscope. Click on the links below to see a detailed description of each microscope.

We have carefully selected our microscopes to offer you the best quality at reasonable prices. You can expect many years of excellent service from Kokopelli Technologies microscopes.

Microscope Features

All Kokopelli Technologies microscopes have the features you need to do semen analysis:

Achromatic, optical glass lenses- Our microscopes have high quality optical components. When you use our microscopes you will be able to clearly see and identify sperm. You must be able to clearly see the sperm to do accurate semen analysis. You can see photos and videos taken through our microscopes.

100 and 400 power viewing- Our monocular microscopes have 40X, 100X, and 400 power. Our binocular and digital microscopes have 40X, 100X, 400X, and 1000 power. You will use the 40 power to practice focusing and to get a "bird's eye view" of things. You will use 100 power to get a wider view to convince yourself you are looking at a representative sample. In cases of low motility you can use 100 power to search for motile sperm. You will use 400 power to count sperm to determine the number of sperm per milliliter.

While you can see the sperm more clearly at 1000X you do not need more than 400 power to do semen analysis. You should use immersion oil at powers higher than 400X. See a primer on Oil Immersion and Refractive Index.

Separate coarse and fine focusing- All but the Model 7 microscope feature separate coarse and fine focusing controls. You will appreciate being able to zoom in with the coarse focus and then use the fine focus to really zero in.

Cool light source- We carry microscopes that have a fluorescent light, an LED light, or a mirror so you don't cook the sperm. Many other brands of microscopes use tungsten or halogen lights. Tungsten and halogen lights are too hot for live samples. They will bake the sperm.

The Model 5 uses a mirror for cool illumination. The Model 5-L has a tungsten light for illumination. We only recommend the Model 5-L if you are not concerned about motility.

A way to control the light intensity- It is much easier to see sperm under low light levels. To be able to see sperm clearly you must be able to adjust the light intensity. All of our microscopes allow you to easily control the light intensity.

In-stage condenser lens- The in-stage condenser lens focuses the light onto the specimen and just fills the numerical aperture of the objective lens. At 400 and 1000 power the in-stage condenser lens significantly sharpens the image. Our Model 5, 5-L, and 7 microscopes do not have a condenser lens.

Still trying to decide between the monocular microscopes? If the Model 10 were a Chevy, the Model 5 would be Volkswagen bug (the old ones, not the new version) and the Model 20 would be a Cadillac. If you can afford it you should purchase a Model 10 or Model 20 microscope. You will be very happy with either of these. If you simply cannot afford the nicer microscopes buy a Model 5 or a Model 7. These will do the job, they are just not as easy to use as the Model 10 or Model 20.

Trying to decide between a Model 10 and a Model 20? If you had the opportunity to use both of them side by side (we have) for about 20 minutes you would chose the Model 20. You would never regret spending the extra money.

After we tried the Model 20 we traded up from our Model 10 and now use the Model 20. The Model 20 has contemporary styling and is slightly larger than the Model 10. You experience less eye strain and have an easier time focusing the Model 20 because of its excellent quality optics.
