LEDs in Life Sciences and Medical Illumination

Traditionally life science and medical endoscopy have turned to the broadband light sources such as mercury, metal halide and xenon lamps to fulfill their demanding illumination requirements. With recent advances in light emitting diodes, these applications are now replacing traditional lamp-based light sources to take full advantage of LED technology. While standard LED sources are fully adequate to cover most of the spectrum required by these applications, specific wavelength requirements in the “green gap” require a clever approach with LED to generate sufficient optical power to effectively image samples.

With illumination technology moving to LEDs, users must be aware of the differences in the peak optical power between lamps and LEDs and ensure optimization of their filters to achieve maximum excitation efficiency of their fluorophores.

Excelitas’ LaserLED Hybrid Drive allows for superior illumination uniformity and maximum light delivery at all wavelengths including the challenging green gap. This enables users in microscopy and endoscopy to visualize molecules with LED illuminators as they would with traditional lamp technologies without any compromise.

Read our technical feature in the February / March 2020 issue of Lighting Magazine to learn how innovative and advanced LED technology developed by Excelitas overcomes this challenging wavelength gap that lies between 540-590nm. Download a pdf copy below or visit Lighting Magazine online at:
