E-Warmer Defog Filter
Photographers may be disturbed by condensation on camera lens in night time and cold weather, happening just 10˚F (5˚C) difference of the dew-point and ambient temperature. STC E-Warmer Defog Filter applies ITO(Indium tin oxide) coating on 1mm optical glass.
Maintaining a specific temperature is essential for the semiconductor-based sensor. It is used to monitor changes in temperature and to offer a linear response to heat up the filter.
By virtue of its high level of transmittance and electrical conductivity, you can warm up your filter with just a smart sensor and a power bank.
