The key factors to consider are: wavelength, power, delivery, repeatability, and cost. 89 North can deliver on all factors.

There are many differences but the four most important are:

  1. Small fiber size. The LDI is available in 100um, 400um, or larger fibers.

  2. Linearity. The LDI is an extremely useful light source for quantitative imagine, with linearity tracked internally from 1% to 100%.

  3. 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.

  4. Stability. The LDI is a very stable light source, which enables both accuracy any precision of light measurements.

Virtually none. The LDI ships fully aligned, and requires no regular alignment or cleaning.

Multi-mode lasers are the most economical lasers you can buy, on a photon/dollar basis. 89 North improves on this value further by providing light sources that are also quantitative and reliable.

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.

Absolutely! The LDI is extremely stable, and linear from 1% to 100%.

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.
