Cutting-edge optical filters with extremely steep transition slopes play an increasingly significant role in our lives. Although invisible to the average user, they are often critical components in both current and next-generation photonics instruments used in telecommunications, astronomy, fluorescence spectroscopy, LiDAR, and laser/Raman spectroscopy. Filters with sharp edges enhance contrast, minimize spectral overlap, increase sensitivity for clear signal separation, and optimize detector performance.
EssentOptics offers exceptional measurement capabilities for such filters using the Photon RT 0420 Ultra spectrophotometer. Below is an example of a nanoband filter with a bandwidth of just 0.57 nm. The signal transition from 80%T to 5%T occurs over a mere 0.2 nm, resulting in an impressive slope steepness of 0.03%.
A very low level of stray light, just one one-hundred-thousandth of a percent, combined with a strong signal, provides a default measurement capability for optical density values as high as OD8. The images below depict measurement results of a bandpass filter with high OD broadband measurement.

The PHOTON RT 0420 Ultra spectrophotometer not only successfully meets current metrology challenges but also inspires coating experts to design and produce sophisticated thin film stacks with very small bandwidth. With its powerful and user-friendly features, achieving success is no longer just a dream. The examples below demonstrate measurements of ultra-narrow bandpass filters optimized for the visible and near-infrared ranges.
The PHOTON RT 0420 Ultra spectrophotometer features a carefully designed additive Czerny-Turner double monochromator, offering an unparalleled spectral resolution of 0.06 nm.
An example below demonstrates the monochromator's ability to distinguish between two closely spaced wavelengths of the mercury doublet. The high spectral resolution of the spectrophotometer enables meaningful measurements of ultra-narrow bandpass filters with steep slopes and small bandwidth.
