Warming the lens to prevent from dewing.
Dew condensation occurs when moist air comes into contact with an object that has a temperature lower than its surroundings, causing the moisture to condense into water droplets. In astrophotography, this often results in lens fogging, especially at night. As the night progresses, the temperature and humidity drop, and the camera lens becomes colder than the surrounding air. To prevent fogging in these conditions, using a lens heater is essential. The Lens Heater 360 III is an essential accessory for astrophotography or night photography in cold environments, such as coastal areas, mountains, or regions with low temperatures.
A Carbon heater with high heat efficiency is provided for it.
The third-generation Vixen 360III lens heater uses high-efficiency carbon heating elements to warm the lens with minimal power consumption. The temperature of the heating element's contact surface is maintained at 10°C above the surrounding ambient temperature (assuming an outdoor temperature of 20°C with no wind). This temperature can vary depending on environmental conditions.
Curled power cord with USB type C connector.
The lens heater 360III comes equipped with a stretchable curl cord. Even 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 has a USB Type-C connector for the power supply.
Energy saving at 3W power consumption.
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 10,000mAh, for instance. (at 20 degrees C ambient temperature.) The operating duration varies widely depending on the environment used.
Self-adhesive soft fabric fastner.
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.
A long strap type dew heater suitable for heating cylindrical surfaces.
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 it to warm a photographic lens or a dew shield of a telescope having a size less than 100mm in diameter.
