TopPride™ filters

DELTA's highest quality fluorescence filters

TopPride™ FSTP 0050: fluorescence filter set for mRFP

Since 2009 DELTA has enriched its catalogue with TopPride™ filters.

This magnificent new range of filters represents the best DELTA can provide in terms of transmission and edge steepness.

All TopPride™ filters are:

Single substrate construction
Without colored glass (minimal lens effect, extreme durability and minimal auto fluorescence)
Ultra Hard Coated using oxide materials
Scratch/Dig Optical Surface Specifications 60/40
Typical transmission level for these filters is 95% - 98% (minimum 92%)
The upper limit of the blocking range has been extended from the traditional 780 nm to beyond 950 nm to better suit modern camera based microscopes
TopPride™ dichroics can be made with low bending by applying a stress compensation antireflex coating on the rear side

Very few companies in the world are able to manufacture filters with these advanced specifications. DELTA's manufacturing technology also enables us to produce TopPride™ filters in large volumes at competitive prices.
