Microscope Coarse Adjustment Knob

Coarse Adjustment Knob

If you’re relatively new to microscopes, you’ve probably heard the term coarse adjustment knob, sometimes referred to as the stage adjustment knob, and you might be wondering what exactly it is and what’s its function.

When you view an object, you position it on the stage of your microscope. The coarse adjustment knob quickly lowers and raises the stage or the lens, depending on the microscope’s design. 


How To Clean a Microscope

How To Clean A Microscope

A Microscope is an expensive piece of equipment, so you must understand how to clean a microscope correctly, so there’s no damage to the sophisticated optics. You also need to maintain its pristine condition.

The optical elements of microscopes require regular cleaning if you want to obtain high-quality images and make microscopy worthwhile. Over time neglecting a microscope’s maintenance will allow dirt, lint, dust, etc., to harm the optics.

Most owners are unsure of how to clean a microscope and how to get the best results without risk to the microscope; this article will discuss the best way to clean microscopes and answer the essential question what do you clean microscope lenses with?


Cheshire Eyepiece VS Laser Collimator

Cheshire Eyepiece VS Laser Collimator – Which One Should You Choose?

Owning a Newtonian reflector telescope means collimation, and you may be wondering if you should use a Cheshire Eyepiece or Laser Collimator.

In fact, you can use both or choose to use only one. For the secondary mirror, you would select the Cheshire eyepiece; however, for the primary mirror’s alignment, a Laser collimator is a better tool for the job. Or if you prefer to buy only one of them, you can collimate your mirrors with either device. It really is down to your personal choice and which you like.

What is a Catadioptric Telescope?

Telescopes are essential devices for any aspiring astronomy enthusiasts. Just to mention, telescopes make it easy to see far objects. Due to their varied use, telescopes come in varying designs, each best for a specific function. Broadly, telescopes can be classified as professional, amateur or commercial types. However, they can also be grouped based on optical design or mechanical design. The other minor classification is based on where they are placed, for instance, space telescopes.

That said, catadioptric telescopes fall into the group of optical telescopes. Also called compound telescopes, they are hybrid scopes which combine lenses and shaped mirrors to form an image of the object. These telescopes combine the best features of reflectors and refractors in one package.

Due to this, they have a greater degree of error correction compared to other lens or mirror counterparts. They also have a wider field of view for an excellent view. (more…)
