Manual Focus Lens Description:
Manual focus infrared lens, also called thermal imaging lens. The focal length can be fine-tuned, which is convenient for users to observe objects at different distances. Therefore, it is generally used in scenes that are easy to focus such as telescopes, infrared sights, infrared cameras, and thermal imaging cameras.
Features of Infrared lens:
Our range of infrared lenses includes manual adjustment lenses, prime lenses and electric long wave infrared lenses. Available focal lengths in stock range from 3.8 to 250. We offer various interface options such as M34x0.5, M45x1, M34x0.5, M34x0.75, C interface and flange. The distance between the lens and the object varies from 13.3 to 61.26.
Germanium is commonly used in long wave infrared lenses. Its strong durability, non-reactive chemistry and Konu hardness make it ideal for harsh environments. However, one disadvantage of germanium lenses is that they are prone to severe defocusing due to temperature changes under certain conditions. If temperature fluctuations are expected, we recommend the ZnSe LWIR lens, which provides a more stable focus even under large temperature variations.
