A curly cord with USB Use by wrapping the strip of the heating elements around the camera lens. The heating element is a carbon fiber heater used widely for its high thermal efficiency. A curly cord with USB Type-C female terminal is equipped. Perfect for prevention against dew of a camera lens, the objective lens of a telescope, or an eyepiece.
Dew condensation is a phenomenon of becoming drops of water that occurs if moisture in the air contacts on an object having in a temperature lower than surroundings. Taking astrophotography at night often suffers with a fogging of the lens. Because the temperature and humidity change as the night progress and the camera is likely to be cooler than ambient temperature. It is essential to keep warming the lens by using heating elements to prevent the lens from fogging in that situation. We recommend using the Lens heater III when you take astrophotography or night photographs at the seashore, mountains, or in cold regions.
The heater elements are carbon heaters of better heating efficiency introduced for the third generation of the Vixen lens heater 360III. It keeps the lens warm efficiently at minimal power consumption. The temperature at a contact surface of the heating element reaches 10 degrees Celsius above the ambient temperature. (at 20 degrees C outside temperature and no wind.) It fluctuates depending on the environment used.
The lens heater 360II is equipped with an elastic curl cord. If you caught the power cord by accident while taking a photograph, the curl cord could help in mitigating vibrations to the camera. The lens heater 360III is provided with a USB Type-C connector for power supply.
The lens heater 360III consumes electricity as low as 3 W (5V - 0.6A). It is possible to run it continuously for about 12 hours with a USB mobile battery of 10,000mA, for instance. (at 20 degrees C outside temperature.) The operating duration varies largely depending on the environment used.
The fabric fastener, which is soft as felt cloth, is made to be self-adhesive on the surfaces. You can take off the fabric fastener without adding extra force to it, unlike conventional fabric fasteners.
The lens heater 360III is made of a 30mm wide and 600mm long strap. It is possible to wind it on a cylindrical object easily. You can use to warm a photographic lense or a dew shield of a telescope having a size less than 100mm in diameter.
