Long Pass Filters

We offer several long pass filters which have been especially designed for use with our fluorescent probes.  These filters are mounted 1 inch round filters.

481 LP

Ideal for excitation < 480 nm, and the collection of fluorescence / phosphorescence > 481 nm.

Transmission dichroic
Absorbance dichroic

Figure 1. Unpolarized transmission, A, and absorbance spectra, B, recorded for filter 481 LP. The filter was oriented perpendicular to the light beam.

 

Ideal for use with: Cyanide Orange; Cyanide Red; Viscous Green 1; DCVJ; Viscous Aqua; Viscous Red; Fluorescein; wt-GFP from Aequorea and Rhacostoma GFP.  Also can be used for isolating the phosphorescence of Phos 1; Phos 2; Methuselah Green 1 and 2, Methuselah Green Carboxy; Methuselah Green Hydroxyl and Phos Hydroxy.

492 LP

Ideal for excitation < 490 nm, and the collection of fluorescence / phosphorescence > 492 nm.
