Introduction to IR Illuminator 940nm

The 940nm IR illuminator is a type of infrared light source that emits light at a wavelength of 940 nanometers. This specific wavelength is within the near-infrared spectrum, which is not visible to the human eye. The 940nm IR illuminator is widely used in various fields due to its unique properties and advantages.

Characteristics of 940nm IR Illuminator

The 940nm IR illuminator possesses several distinct characteristics that make it suitable for different applications: 1. Non-Visible Light: As mentioned earlier, the 940nm wavelength falls within the near-infrared spectrum, making the light emitted by the illuminator invisible to the naked eye. This is particularly useful in applications where it is important to avoid visual distraction or interference. 2. Long Wavelength: The 940nm wavelength is relatively long compared to other infrared wavelengths. This results in a greater depth of penetration in materials, making it effective for applications that require the illuminator to pass through objects or surfaces. 3. Low Cost: The 940nm IR illuminator is generally more affordable than other types of infrared illuminators. This is due to the lower cost of the materials and the simpler manufacturing process. 4. Low Power Consumption: These illuminators are designed to be energy-efficient, consuming less power than other types of infrared illuminators. This is beneficial for battery-powered devices and helps to extend their operational time.
