Product Description

This is an inexpensive, but effective, cleaning tool that you can take in the field for quick optical touchups on your eyepieces, small refractor telescope, binocular, or spotting scope. The size and shape of a thick ballpoint pen, it has a clip that will keep it handy in your shirt pocket for immediate use. Due to its small size, it is impractical to use the Lens Pen to clean large optical surfaces, such as a Schmidt-Cassegrain corrector lens. However, it can be used to spot clean relatively small areas of a large optical surface, and is the right size to keep smaller optics clean.

The Lens Pen is safe for all optical lenses, including multicoated surfaces. It quickly cleans fingerprints, smudges, grease marks, eyelash oils, and dust off lens surfaces. It uses a unique dry cleaning compound that will not spill or dry out. The compound is non-toxic and environmentally friendly.

How to use the Lens Pen: The Lens Pen contains two parts in one body. At one end of the Lens Pen is a soft retractable brush that is used to gently remove loose dust from the surface of your optics. A cap at the other end of the body conceals a unique flexible 9/16" diameter cleaning pad. Using a smooth circular motion, gently wipe the lens surface with the cleaning pad to remove fingerprints and oils from the lens surface. If smudges persist, breathe gently on the lens surface and repeat the cleaning process. When finished, replace the cap over the cleaning pad and give the cap a half twist. This will replenish the cleaning pad compound.

I find that it removes light dust and light surface marks from dew very nicely. The brush fits well into most eyepiece barrels. To perform a thorough cleaning you would still need to use a good cleaner like ROR, but this works extremely well for light duty cleanup and maintenance. (Posted on 8/5/2019)

This is a decent cleaning tool for eyepieces and small aperture refractors when used correctly. Personally, I use a blower bulb followed by an anti-static brush before using the retractable brush or cleaning pad. One word of caution take your time and only focus on cleaning small sections until the whole lens is completed if you decide to use it on anything larger than an eyepiece. Also, it helps if you are inside (or in a relatively dust and particulate free environment) and have a bright light on the areas you are cleaning. (Posted on 7/27/2019)

For its price, this is a good lenspen cleaning tool. There are better choices but obviously, they will end up being more money. I mainly only use this when I want to clean an eyepiece quickly so I can get to observing. It does its job with getting the dust off the surface if you are very gentle, that is the key with this optics cleaning tool. (Posted on 1/12/2019)

These Lenspens are great for cleaning small areas like eyepieces and sections of camera lenses. First use the retractable brush to remove any large pieces of dust particles. Then pop the cap off of the liquid-free carbon cleaning tip and gently rub it around the surface. It will remove any leftover gunk. The original Lenspen is the best -- I believe this is that and Celestron just put their name on it.
A very useful tool to have with you in the field.

Works great for cleaning off loose eyelashes and specs from eyepieces. (Posted on 12/31/2018)

As I often have young children looking through my telescope, smudges from curious fingers and oil from eyelashes contacting the glass are common. The Lens Pen does a great job of cleaning these off - just be sure to carefully dust the surface of the glass with the retractable brush before using the cleaning pad. (Posted on 10/18/2018)

There are a number of folks that a apprehensive about a reusable cleaning surface due to the possibility of crud getting stuck in the pad and scratching coatings. However, these Lens Pen tools are in my experience safe and very handy for a minor cleaning of the eyepiece eye lens surface, as long as you keep a few things in mind. Firs off, DO NOT clean your eyepieces in the field conditions. There will be particles on the surface that you will not be able to see, which can damage the surface. Ensure you have good (bright) lighting. Use the retractable brush and a bulb blower to ensure that no debris remains on the lens, then gently use the cleaning tip to remove and residue / gunk that exists on the surface. I also closely inspect the tip of the cleaning pad before use and prior to recapping it. With all that in mind, this thing is absolutely great if you find oil from eyelashes etc on your eyepiece after an observing session. I would not recommend using this to clean a lens / mirror / corrector plate of a telescope however. (Posted on 10/15/2018)
