There are three models in the iBright Imaging Systems family: The iBright CL750 Imaging System, the iBright CL1500 Imaging System, and the iBright FL1500 Imaging System. The iBright CL750 Imaging System offers the core essential western blot and gel imaging functions and makes the transition from the darkroom and film easy. The iBright CL1500 Imaging System expands application support and has many of the high-performance specifications of our premier iBright FL1500 model. The iBright FL1500 Imaging System features maximum application support, including fluorescence western blot imaging with up to four fluorescence channels at a time.

Qualitative visible imaging applications**
Translucent objects (e.g., colony plates)

Opaque objects (e.g., 2D strips, TLC plates, leaf sections)


GFP expression in multiwell plates (e.g., 6-well)  


Detector Cooled 16-bit CCD, 65,535 shades of gray
Resolution 9.1 megapixels
Lens Fixed, 25 mm, f/0.95
Field of view 22.5 x 18.0 cm (W x D) (image up to 4 mini blots or gels)
Binning modes 1x1, 2x2, 4x4 (high-resolution/sensitivity settings)

1x1, 2x2, 3x3, 4x4, 5x5, 6x6, 8x8 (maximum flexibility for adjusting resolution and sensitivity based on needs)
