Before 2023 comes to an end we want to go on record with three things that we guarantee will happen in 2024.
(Guarantee not valid anywhere, anytime, and/or any place. Void everywhere.)

It’s that time again. Let’s take a look at the most-read articles that appeared on Photonics Online this year. It’s got intrigue, suspense, and surprises. Oh, and infrared, LiDAR, and so much more.
-
Cold mirrors are much like hot mirrors in that they are used to separate IR from the non-IR. Discover the distinctions between the two and which applications benefit from using cold mirrors.
-
Narrow dual band pass filters, designed and produced mostly for DWDM modules, improve a module’s total insertion loss by reducing the number of components used.
-
Understanding the mechanical dimensions of optical filters, particularly parameters like clear aperture and parallelism, is paramount for ensuring proper functionality.
-
Surface quality standards establish acceptable flaws on optical components that affect performance. Proper specification of these standards is crucial to achieving performance balance.
-
Thoughtful design and substrate selection are vital to minimize substantial shifts in interference filter spectra due to temperature fluctuations.
