The OD8-EM693-56-B is an emission filter in the ODiate® Fluorescence Filter Sets series, designed for fluorescence imaging applications with a center wavelength of 693 nm and a bandwidth of 56 nm. It is housed in a 25.0 mm diameter mount with a substrate thickness of 2.0 mm ± 0.1 mm and a scratch-dig specification of 60-40 over 21 mm clear aperture. The filter achieves average transmission ≥ 96% within its passband and blocking ≥ OD10 over the corresponding excitation passband, verified to OD8. It operates at an angle of incidence of 45° ± 1.5° with a cone half angle < 2°, and exhibits a transmitted wavefront error ≤ 1 wave PV @ 632.8 nm. The substrate material is Schott BOROFLOAT® 33, with an orientation arrow indicating light propagation direction.
The OD8-EM693-56-B Emission Filter is specified for emission of Cy5™ and supports similar alternative fluorophores, designed in conjunction with and . The filter is manufactured to provide maximum signal and sensitivity delivering exceptionally high passband transmission ≥ 96% avg for 693 nm CWL and 56 nm FWHM and enhanced blocking ≥ OD10 avg over the corresponding excitation passband.
Alternate Fluorophores
In addition to Cy5™ the following fluorophores are also compatible with this set:
Abberior STAR 635, Abberior STAR RED, Alexa Fluor® 647, Alexa Fluor® 660, APC, ATTO 635, ATTO 647, ATTO 655, BODIPY® 650/665-X, C5-Thiacyanine, Carboxynapthofluores
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.
