ODiate® Excitation Filter, 25.0 mm, 380 nm CWL, 59 nm FWHM

The OD8-EX380-59-B Excitation Filter is specified for excitaiton of DAPI and supports similar alternative fluorophores, designed in conjunction with and . The filter is manufactured to provide maximum performance delivering exceptionally high passband transmission ≥ 96% avg for 380 nm CWL and 59 nm FWHM and enhanced blocking ≥ OD10 avg over the corresponding emission passband.

Alternate Fluorophores

In addition to DAPI the following fluorophores are also compatible with this set:

Alexa Fluor^® 350, AMCA, ATTO 390, CF350, EBFP, Brilliant Violet 421™, HCS CellMask Blue, Hoechst^® 33258, Marina Blue^®, Pacific Blue, PromoFluor-350, PromoFluor-370LSS, sgBFP, Spectrum Blue, TagBFP, Vybrant^® DyeCycle Violet.

Optimized Coatings and Engineering Expertise

Newport pushed the boundaries with the introduction of our ODiate Fluorescence Filter Sets, to allow customers to fully optimize their system performance. Our expert engineering team has been involved from the first stage of design to ensure that we exceed your requirements and continues through the entire process of continual production deliveries.

Environmental Stability and Physical Durability

The coating systems used to produce ODiate filters use a dense sputtering process to provide robust environmental reliability to meet the highest demands for thin-film coatings. The resulting highly durable coatings meet or exceed testing procedures including humidity, thermal shock, adhesion, chemical resistance, and moderate abrasion per U.S. Military and international standards.
