Considerations when specifying transition pass bands, blocking bands, and transition widths include filter manufacturing tolerances, thermal tolerances and source/detector variations among others. These factors must be taken into account properly and completely in order to achieve the spectral performance required for an application.
The next advances in communications, 5G and machine-to-machine communications, will require “help from above” to blanket literally every corner of our planet with high-speed, ultra-low latency, secure networks — telecom meet satcom.
This white paper helps the reader understand where, when, how, and how much to specify wavefront distortion to ensure that functional requirements of filters are guaranteed while unnecessary and costly constraints are avoided.
The evolution of sensing and imaging systems, combined with the desire to create safer, more efficient transportation systems, is driving the development of autonomous vehicles. LiDAR is a key technology that will eventually help carry this growth through to “Level 5” autonomy.
Midwave infrared (MWIR) light is important in many hardware applications, and optical filters are critical to success. Some simple practices can help avoid over-specifying filter characteristics and driving up costs.
