Overview
Dust Cap 50 mm Inner Diameter Push-On Cover for Telescope Eyepiece and Lens Depth 7 mm Black Plastic Optical Protection

The dust cap with an inner diameter of 50 mm is a simple and practical accessory for anyone working with optics. It fits onto the eyepiece of a telescope, the lens of a camera, or any other cylindrical part of an optical device with an outer diameter of 50 mm, protecting the front lens from dust and dirt. The cap is made from black plastic, making it lightweight and easy to handle. It fits conveniently into an accessory bag, into the case with the telescope, or into a drawer where eyepieces and lenses are stored. Thanks to its simple design without springs and latches, it can be put on and taken off with a single motion.

The cap has the shape of a low cylinder with a flat top and a ribbed edge. The internal depth of 7 mm allows the cap to hold onto the edge of the eyepiece or lens, covering the entire front surface. The ribbing around the edge facilitates gripping, so you can easily remove the cap even in the dark while observing the night sky. The size of 50 mm corresponds to the inner diameter of the cap, so be sure to measure the outer diameter of the part you wish to fit it onto before selecting. If you have multiple eyepieces or lenses with different diameters, you can combine caps in the necessary sizes.

The cap is useful wherever the optics have a cylindrical end with an outer diameter of 50 mm. Typically, this includes eyepieces of astronomical telescopes that are stored in a case after observation, as well as smaller lenses or various optical attachments. Those with multiple eyepieces in their case will appreciate that each can have its own cap, preventing scratches or dust accumulation during transport. The cap is thin-walled, so an eyepiece with the cap on takes up only slightly more space in the foam padding of the case than without it. Before fitting, simply check that the outer diameter of the optics matches the size of the cap.

  • Type – push-on dust cap

  • Shape – low cylinder with flat top and ribbed edge
  • Use – eyepieces of telescopes, camera lenses, and other optics with an outer diameter of 50 mm

Occasionally wipe the cap with a dry or slightly damp cloth to prevent dust from transferring to the optics. Before fitting, ensure that the lens surface is clean and dry. When not in use, store it in a case or pocket of the bag to prevent loss and to avoid collecting dirt. Do not expose the plastic to high temperatures for extended periods, such as on a car dashboard in summer.

The 50 mm plastic cap is a simple way to protect eyepieces and lenses that are not currently in use. It is suitable for astronomers, photographers, and anyone storing optics in a case or bag. It fits without tools and, thanks to the ribbed edge, is easy to hold in your fingers. Choose the size 50 mm according to the outer diameter of your device and keep your optics covered during storage and transport.
