Astronomical Telescope Defogging Heating Strip For Camera SLR Lens

Description

Astronomical Telescope Defogging Heating Strip For Camera SLR Lens
Feature:
1. Designed specifically for astronomical telescopes: protect optical equipment such as telescopes from fogging or freezing. Compatible with astronomical primary mirrors of OD below 152mm or Camera Lenses.
2. 5.5X2.1 female interface design，easy connected to various 12V power inputs.
3. Three-speed regulator with medium weak heating mode. You can adjust the temperature according to different usage requirements. Super-fast continuous heating, quick start heating.
4. The narrow width of 50mm will not interfere with focusing, and will not produce vignetting in the field of view; the width also reduces the interference of other accessories on the lens barrel.
5. Good heat preservation effect: imitating OK cloth, SBR and Black-T three-layer heat preservation material, reducing heat dissipation, and no wrinkles on the inner surface after bending. It is more suitable for the lens barrel and increases the warmth retention effect.
6. Uniform heating: the built-in aluminum film has a uniform heating surface and no dead ends.
7. TPE Silica of material  the power cord  low temperature non-become hard.
8. Safe use and prevent short circuit. Alloy fiber heating wire can provide super-fast continuous heating. The silicone insulation process prevents internal short circuits.
