Characteristics of Alternative IR Wavelengths
Infrared transmitters operating beyond the standard 850 nm and 940 nm bands exhibit distinct optical behavior that supports application-specific system design.
Alternative wavelengths can align with sensors designed for different or extended spectral sensitivity ranges.
Longer or shifted wavelengths may interact differently with surfaces and materials in terms of reflection and absorption.
Operating outside common IR bands helps minimize interaction with widely used consumer infrared sources.
Non-standard wavelengths allow greater freedom for specialized, proprietary, or function-defined system architectures.
Why Use Non-Standard IR Wavelengths
While 850 nm and 940 nm infrared emitters are widely adopted, they are not universal.
- Alternative IR wavelengths are often selected when applications require:
- Different optical interaction with materials or surfaces
- Detection behavior aligned with specific sensor response ranges
- Functional separation from common consumer IR sources
- Application-defined wavelength positioning rather than convention
In these cases, wavelength choice supports how the system functions, not how commonly the emitter is used.
Where Other IR Wavelengths Are Applied
- Systems using non-standard optical filters or lenses
- Detection setups based on photodiodes optimized beyond 850 / 940 nm
- Applications utilizing wavelength differences for signal identification or separation
- Designs that intentionally avoid overlap with widely used IR communication bands
- Specialized sensing or control systems with application-specific optical behavior
Choosing the Right Wavelength
- If your application is designed around a defined optical wavelength range, selecting an IR transmitter outside standard bands helps maintain alignment with system intent.
- This option is best suited for projects where:
- Wavelength is predefined by design
- Functional differentiation is required
- Standard IR bands are not part of the system strategy
For general IR communication or consumer-style remote control systems, standard 850 nm or 940 nm options are typically more appropriate.
