Vixen Lens Heater 360 IV

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 low temperatures . A very flexible Velcro tape allows for quick and easy attachment to and removal from 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 14 hours .

The Vixen Lens Heater 360 IV in detail

When moisture in the air comes into contact with an object whose temperature is lower than the ambient temperature, small drops of water form - so-called dew condensation. Astrophotography often suffers from such lens fogging and the photo turns 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 objectives or telescopes lens by using heaters to prevent it from fogging.

We recommend using the Lens Heater 360 IV 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 fourth generation Vixen Lens Heater 360 IV. 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.

For power supply the lens heater is equipped with a detachable coiled cable (USB Type-C) ,up to 50 cm long. The 360 IV lens heater consumes only 2.5 W of power (5 V - 0.5 A) . With a portable USB battery of e.g. 10,000 mA, it can operate continuously for about 14 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 allows for easy attachment 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.
