Additional Information

  • Background

    AbFluor™ 633 is a far infrared fluorescent dye, which has bright fluorescence and strong light stability. The absorption peak of AbFluor™ 633 is 630 nm, which can be best match of 633 nm hene laser or 635 nm red diode laser. The emission peak of AbFluor™ 633 is 650 nm. AbFluor™ 633 is brighter than other dyes. In addition, the more important advantage of AbFluor™ 633 is its incomparable light stability. AbFluor™ 633 is the best choice for equipment with 633 nm or 650 nm laser excitation system.
