Hey there! As a supplier of DIP IR LEDs, I often get asked about the peak wavelength of these little guys. So, I thought I'd take a moment to break it down for you.
First off, let's talk about what DIP IR LEDs are. DIP stands for Dual In - line Package, which is a common way to package these infrared light - emitting diodes. They're used in a whole bunch of applications, from remote controls to security systems, and even in some medical devices.
Now, the peak wavelength of a DIP IR LED is a super important characteristic. It basically tells you the wavelength at which the LED emits the most light. You see, light is made up of different wavelengths, and infrared light is just a part of the electromagnetic spectrum that has longer wavelengths than visible light.
Most DIP IR LEDs have peak wavelengths in the range of 700 nanometers (nm) to 1600 nm. The most commonly used ones are around 850 nm and 940 nm. Why these two? Well, they've got some pretty cool properties.


Let's start with the 850 nm DIP IR LEDs. These are often used in security cameras and surveillance systems. The reason is that they emit a faint red glow that's just on the edge of what the human eye can see. So, while it's not very noticeable to us, cameras can pick up the infrared light really well. This makes them great for night - vision applications. If you're in the market for 850 nm DIP IR LEDs, you might want to check out our 5mm Infrared LED Emitters. They're high - quality and have a nice, consistent peak wavelength.
On the other hand, 940 nm DIP IR LEDs are completely invisible to the human eye. That's why they're used in things like remote controls. When you press a button on your TV remote, you don't want to see a red flash every time. These LEDs are also more efficient in some cases, which means they use less power to emit the same amount of light. If you're looking for a more powerful option in this wavelength range, our 0.5W IR LED could be a great fit.
But how do we actually measure the peak wavelength of a DIP IR LED? Well, it's done using a spectrometer. This is a device that can split light into its different wavelengths and measure the intensity of each one. By analyzing the data from the spectrometer, we can figure out the exact peak wavelength of the LED.
Now, the peak wavelength can be affected by a few things. One of the main factors is the temperature. As the temperature of the LED changes, the peak wavelength can shift a little bit. This is something to keep in mind, especially if your application is going to be in a place with extreme temperatures.
Another thing that can affect the peak wavelength is the current flowing through the LED. If you increase the current, the peak wavelength might change slightly. That's why it's important to use the right power supply and make sure you're operating the LED within its recommended current range.
When it comes to choosing the right peak wavelength for your project, you need to think about what you're using the DIP IR LED for. If you're building a night - vision system for a security camera, 850 nm might be the way to go. But if you're making a remote control, 940 nm is probably a better choice.
We also offer 3mm Infrared Lamp LED Emitters which come in different peak wavelengths. These smaller LEDs are great for applications where space is limited, like in some portable devices.
As a DIP IR LED supplier, we make sure to test each and every LED to ensure that it has the correct peak wavelength. We use state - of - the - art equipment and follow strict quality control procedures. That way, you can be confident that you're getting a high - quality product that will perform as expected.
If you're interested in purchasing DIP IR LEDs for your project, we'd love to hear from you. Whether you need a specific peak wavelength or a certain package size, we've got you covered. Just reach out to us, and we can start a discussion about your requirements. We can provide samples so you can test them out in your application before making a large - scale purchase.
In conclusion, the peak wavelength of a DIP IR LED is a crucial factor that determines its suitability for different applications. Whether it's 850 nm for visible - edge infrared or 940 nm for completely invisible operation, understanding this characteristic will help you make the right choice for your project. So, don't hesitate to get in touch with us if you have any questions or if you're ready to start sourcing DIP IR LEDs.
