Omega Optical, Inc. is an innovator in the field of photonics, located in Brattleboro, Vermont. Founded in 1969 by Robert Johnson D.Sc.. Omega has been producing filters for fluoerescence since the 1970! We have the experience and the technology to deliver you a custom solution that is tuned to your application. We are ready to solve your optics problems!

Omega Optical can manufacture filters from prototype to production. This flyer describes our primary applications, capabilities and how we can guide you to choosing the filter you need.

To understand blocking, one has to understand the concept of optical density (OD). In an interference filter, OD is generated by reflecting unwanted light back instead of letting it go through the filter.

In this technical note, we will go through an example of how to determine the blocking level needed in a typical flow-cytometer system.
