Vixen Lens Heater 360III

The 360III lens heater is designed to prevent camera lenses and telescopes from fogging up due to dew. It is also well suited for eyepieces.

The heating element is a carbon fiber heater, with a high thermal efficiency. The textile heating element provides great flexibility compared to other heating materials. The power cord (USB cable) has a particularly high flexibility to be still elastic at a low temperature. A very flexible Velcro tape, allows quick and easy attachment and removal to the lens. The tape can be easily removed from the lens without pulling tightly. The heating tape has a very low power consumption and can be operated with a 10,000 mA battery for up to 12 hours.

Dew condensation is small water drops that form when moisture in the air comes into contact with an object whose temperature is below ambient. Astrophotography often suffers from such lens fogging and the photo becomes milky. Because the temperature and humidity change during the night and the camera becomes cooler than the ambient temperature, it is important to warm the lens of the objective or telescope by using heaters to prevent the lens from fogging. Therefore, we recommend using the Lens Heater 360 III when you want to do astrophotography or night photography on the coast, in the mountains or in cold regions. The heating elements are made of carbon fibers with improved heating performance, introduced for the third generation Vixen Lens Heater 360III. They efficiently keep the lens warm and fog-free with minimal power consumption. The heater temperature reaches 10 degrees Celsius above the ambient temperature. (At 20 ° C outside temperature and no wind). However, it varies according to influences in the environment. The lens heater is equipped with a detachable coiled cable (USB Type-C) up to 50 cm long for power supply The 360III lens heater consumes only 3 W of power (5 V - 0.6 A). With a portable USB battery of, for example, 10,000 mA, it can operate continuously for about 12 hours (at 20 ° C outdoor temperature). However, the operating time varies greatly depending on the environment and temperature. The soft and non-slip surface of the heating tape, allow easy and attach to the objective, eyepiece or telescope. The heater consists of a 30 mm wide and 600 mm long heating tape and is suitable for diameters up to 100 mm.
