KolaDeep™ Spectral Measurement System: Measure Deeper Blocking

New fluorescence-based life science and biomedical instrumentation increasingly requires high-performance optical filters with very high blocking (OD) and steep spectral edges that transition between high transmission and high OD. IDEX Health & Science Semrock engineers therefore developed the KolaDeep Spectral Measurement System (SMS), a proprietary award-winning platform for proven measurements of the steepest and deepest spectral features of our optical filters. This system is used in routine production to ensure that instruments made from these filters will deliver their intended performance.

The graph above shows OD measured on a custom pentaband filter.

The blocking between passbands is specified to exceed OD 8 to prevent excitation light leakage. Theory and measurement agree to OD > 8, with some blocking reaching from OD > 9 to the noise floor.

When choosing a partner for your custom optical filters needs, it’s important to have proven data behind specifications. Contact us to discover how Semrock can provide actual data measurements of your custom optical filters with the KolaDeep™ Spectral Measurement System.
