Spectral Curves

The spectral curve and ascii data is a typical representation of this filter’s performance, but will vary due to production and design variations. Omega only guarantees this part to meet the product specifications listed. The displayed OD is calculated from a %T measurement. The blocking regions are likely higher OD than what is displayed here. To learn more about the challenges of measuring high OD values, see our paper.
