Prior Scientific LED Light Sources
BioVision Technologies offers the following range of Prior Scientific LED illumination products for brightfield and fluorescence microscopy applications:
Lumen 100-LED Fluorescence Illumination System
The Lumen 100-LED illuminator provides advanced, high quality illumination for a wide range of fluorescence microscopy applications. A wide range of adaptors are available to connect the L100-LED to most upright and inverted microscopes. A broad array of LEDs covering wavelengths throughout the visible spectrum are available and are suitable for the majority of fluorophores used in fluorescence applications. A combiner is also available if two LEDs need to be used simultaneously. Excitation filters can be added to LEDs to further optimize the bandwidth for your specific application.
Features
- Precise intensity control in 1% increments
- Up to 11 LED’s available (additional wavelengths to be added)
- Adapters to fit all major microscope manufacturers
- Long lifetime (25,000 operating hours)
- Increased energy efficiency
- Instant On/Off control
- Direct coupling to fluorescence port to maximize light efficiency
- Silent operation
- No Mercury
- No bulb replacement
- No alignment necessary
- USB control for OEM integration
Lumen 300-LED White Light Fluorescence Excitation Illumination System
The Lumen 300-LED is specifically designed to offer broad‐spectrum LED illumination for fluorescence applications. Fitting directly to most microscopes, the system is simple to install and use. Controlled by a manual keypad controller, the Lumen 300‐LED offers instant on/off operation via TTL, manual 0–100% intensity control in 1% increments and on/off control for each LED. An optional liquid light guide is available to keep the illumination source remote from the microscope. Providing 25,000+ hours of bulb life, the Lumen 300‐LED is an environmentally friendly illumination system that requires no special disposal regulations.
Users of triple multiband filter sets should be aware that DAPI is typically excited at longer violet wavelength (400 nm) than the common UV band (365 nm). To match these triple multiband filter sets, the Lumen 300‐LED in multiband ("MB") format should be specified.

Lumen 1600-LED Fluorescence Illumination System
The Lumen 1600‐LED offers individual control for 16 selectable wavelengths. With its unique 16 selectable LED wavelengths, the Lumen 1600‐LED is compatible with all simple and multiband filter sets. For the user who wants ease of use, the Lumen 1600‐LED has a “white light” mode with simple on/off and intensity buttons. Fitting directly to most microscopes the system enables for rapid switching between LED wavelengths to allow for capture of high speed events. The Lumen 1600‐LED is controlled via a manual keypad controller, TTL, and USB as well as analog input for dynamic intensity control. Excitation filters can be fitted in the optical path for controlled switching with no moving parts. Providing 25,000+ hours of bulb life, the Lumen 1600‐LED is an environmentally friendly illumination system that requires no special disposal regulations.
