The bibulous paper is high quality, low linting, and low shedding, which is ideal for drying microscope slides.
WHAT IS lens paper made of?
A soft, thin, lightweight, lint-free, nonabrasive Paper designed for wrapping or polishing optical lens. Lens tissues are usually made from unbleached or Mechanical wood pulp. They have been used for interleaving, lamination, and paper repair. Some lens tissue may contain silicone oils.
Is lens paper and lens tissue the same?
Yeah, this. “Tissue paper” and “lens tissue” are not the same thing. But regardless of material, the presence of grit or any other hard particles on the lens can cause scratches, which is why lens pens have a soft brush for getting rid of the grit first before you start wiping the surface of the lens.
Why should only lens paper be used to clean microscope lenses?
why should only lens paper be used to clean microscope lenses? The glass on the lens is softer and will scratch easily.
Why must you use special lens paper to clean the eyepiece and the objectives?
Why is lens paper used to clean the microscope lenses? It has extremely fine, soft fibers. Other types of paper have coarser fibers that will gradually scratch the lenses causing them to become foggy and blurry.
What do you use to clean the lenses of a microscope?
To clean microscope eyepiece lenses, breathe condensation onto them and then wipe them with lens tissue. Kim-wipes are made by Kleenex and generally will work well. For stubborn spots, wipe the surface with tissue moistened with 95% alcohol. Wipe the lens dry with a dry tissue.
How do you store a microscope?
Storage
- Always cover the microscope with the supplied dust cover when not in use.
- Store in a dry place.
- In humid or moist environments, it is advisable to store the microscope in a waterproof container with a drying agent.
- Do not touch the optical lens with bare fingers.
- Do not store the microscope in direct sunlight.
What should you only use to clean the lenses of the microscope?
Remove oily dirt using either a lens cleaning fluid or absolute ethanol on a cotton swab or lens tissue. Stubborn contamination may require several passes, or a stronger solvent such as methanol or acetone.
Why are microscope lenses not touched?
Never touch the lenses with your fingers. Your body produces an oil that smudges the glass. This oil can even etch the glass if left on too long.
What is the tissue used to clean lenses?
Once blown clean, lightly wipe the lens with Kimwipes or another approved lens cloth. Another good cleaning tissue is Kodak Lens Tissue (available at photo stores) In lieu of a brush, you can use the paper.
When should the lenses be cleaned?
If the spot doesn’t move when you turn the eyepiece lens and you see it at all powers then the dirt is internal and you should probably have it cleaned by a professional. If you only see it at one power, the dirt is most likely on that particular objective lens. Sometimes all you need to do is blow off the residue.
Can I use glasses cloth to clean camera lens?
Can you use glasses cleaner on camera lens? Yes, glasses cleaner is an excellent way to clean your camera lens along with a microfiber cloth or special lens cleaning tissues.
Can you use 100x objective without oil?
Never use the 100x objective without using immersion oil. When you have correctly brought your slide into focus up to 40x (step 3), then: a. Turn the nosepiece half-way between the 40x and 100x objectives.
How is xylol used to clean the lens of a microscope?
The most widely used technique to clean the objectives of a microscope, especially the 100X objective, involves wiping out of immersion oil from the same and its surrounding mount by a piece of lens paper or a soft piece of clean cotton cloth followed by a cloth dampened with small amount of xylol.
Which objective lens should be used first?
When focusing on a slide, ALWAYS start with either the 4X or 10X objective. Once you have the object in focus, then switch to the next higher power objective. Re-focus on the image and then switch to the next highest power.
Which parts of microscope contain lens?
What are the two main parts of the microscope? The compound microscope has two systems of lenses for greater magnification, 1) the ocular, or eyepiece lens that one looks into and 2) the objective lens, or the lens closest to the object.
What is immersion oil used for?
Immersion oil increases the resolving power of the microscope by replacing the air gap between the immersion objective lens and cover glass with a high refractive index medium and reducing light refraction.
Does light enter the eyepiece first?
The light then enters the objective lens (4) and the image is magnified. Light then passes through a series of glass prisms and mirrors, eventually entering the eyepiece (5) where is it further magnified, finally reacing the eye. First let us consider a primary feature of all microscopes, the light source.

What particular material is used in cleaning lenses of the eyepiece and the objective?
Xylene is a popular solvent for cleaning of objectives and has been much preferred particularly for more stubborn stains. Considered caution is advised due to carcinogenic properties. Xylene almost always leaves a small residue where the last of it evaporates. When this is the only defect remaining, use a dry swab.
