There are many differences but the four most important are:
Small fiber size. The LDI is available in 100um, 400um, or larger fibers.
Linearity. The LDI is an extremely useful light source for quantitative imagine, with linearity tracked internally from 1% to 100%.
Specificity. The wavelengths of light from the LDI are not broad in spectrum line an LED. They are highly specific, which is critical for fluorescent illumination.
Stability. The LDI is a very stable light source, which enables both accuracy any precision of light measurements.
Many factors, like wavelength, stability, and maintenance are critical issues that are often overlooked. Don’t just pay attention to cost, as all lasers are not the same.
The LDI is about the size of a small desktop computer. The dimensions are 12.5” x 9.2” x 5.75”, 318mm x 234mm x 146mm. You can find more specifications in the table at the top of the page.
The single most important thing to remember when setting up any laser light source is safety. Always review all documentation carefully, and consult your institution’s laser safety officer with any questions.

Large vesicle extrusions from C. elegans neurons are consumed and stimulated by glial-like phagocytosis activity of the neighboring cell.
The LDI-NIR is the same great multiline, solid-state laser illuminator as the LDI-7, but offers more power and extends the range into the NIR. This affordable multi-mode laser launch will change how you imagine laser illumination.
The LDI-5 is the big sister of the LDI-4 laser diode illuminator. Once again we listened to our users who asked for a pared down version of the LDI-NIR. The LDI-5 has increased power over her little sister and expands into the near infra-red with the addition of a 730nm line. This unit is also available with a 488nm laser for FITC/GFP and with a 577nm laser for TRITC/mCherry…or both!
