Microscope Lighting

Replacement microscope illumination

LED microscope lights are versatile plug & play solutions to enhance your microscopy or other high-tech illumination demands.  They are also utilized in a wide variety of research and industry applications.  These LED lights can save up to 80% in operational costs over their long lifetimes.  

The NEW 8-channel Multilux light system incorporates a simple user interface and delivers consistent high performance. The cost-effective long-life LED bulbs eliminates the need to replace bulbs across multiple lights over time.

Reduce hardware, confusion and cost with an all-in-one single light source that allows you to switch quickly between multiple light wavelengths.  This is ideal for fluorescence microscopy and multispectral imaging.

LED lights offer high quality intense light with minimal heat generation.  They are good alternatives to halogen or short-arc cold light sources. Models range in brightness up to 1000 lumens.  Pulse operation is available on some models up to 100 kHz.  Using LEDs the nm wavelength (color temperature) is adjustable for your application.  The Deep UV system delivers stable UV radiation, and is often used for wafer inspection and photomask analysis.
