The FLPIRR2 series from Bivar, Inc., consists of 4mm round light pipes designed for both LED and IR940 lighting applications. These light pipes are versatile and commonly used in projects requiring efficient light transmission over short distances. If you're working on optical systems that need to distribute light evenly across a surface or channel light from an LED to a specific area, these light pipes are a go-to solution.

One thing worth noting is their compact design, which makes them ideal for space-constrained applications. Engineers tend to reach for this when they need a reliable way to transmit light without significant loss or distortion. Another practical benefit is their ability to handle both visible and infrared wavelengths, making them suitable for a wide range of projects from consumer electronics to industrial sensors.

These light pipes are particularly useful in applications like optical switches, where precise light transmission is crucial, or in automotive lighting systems where visibility needs to be optimized. Their robust construction also ensures longevity and durability, even in environments with varying temperatures and mechanical stresses.
