OUTLOOK YJQN-1 Handheld Thermal Imaging Laser Bird Repeller for airport.

ED lenses use ultra-low dispersion glass by reducing the difference in refractive index of light of different wavelengths, chromatic aberration (such as purple fringing) is significantly reduced. Especially in high-magnification or high-contrast scenes (such as astronomical observation, bird watching), ED lenses can provide sharper and more realistic images.

For long-term storage, a ventilated, dry and temperature-stable environment (ideal temperature 20-25℃, humidity below 65%) should be selected to avoid fogging or moisture on the lens due to excessive temperature difference. It is recommended to place a desiccant in the storage box and replace it regularly. In the humid areas in the south, a moisture-proof box can be used additionally.

The Type 62 telescope is an excellent product with excellent optical performance, excellent durability and powerful functionality as its core advantages.
