High Power LED Transmitted Light - LED505/470-TR8W

High Power LED Transmitted Light
- LED505 / LED470-TR8W

Blue 470 nm and cyan 505 nm transmitted fluorescence excitation for stereo microscope observation

LED505-TR8W and LED470-TR8W are compact, high-power transmitted LED light sources designed for fluorescence excitation from directly beneath the microscope stage. The system combines strong excitation output, front dimming control and a dichroic-filter-based optical design to help reduce unwanted background glow during fluorescence observation and imaging.

Compact transmitted LED excitation

High power LED transmitted light for fluorescence excitation microscopy
  • Direct LED emission from beneath the microscope stage.
  • Available in 470 nm blue and 505 nm cyan excitation models.
  • Useful for fluorescent gels, stained samples and stereo microscope fluorescence workflows.
  • Front dimming control supports brightness adjustment for observation and image capture.
Model selection note Select 470 nm or 505 nm according to the excitation range of the fluorescent reagent or sample. A suitable emission filter is typically required for observation.

Features

Blue 470 nm and cyan 505 nm LED transmitted light

High-power excitation from below

The LED is positioned close to the sample and emits excitation light directly upward from beneath the stage.

Dichroic filter performance for fluorescence observation

Reduced background glow

A multilayer dichroic filter helps sharply control residual wavelengths at the longer-wavelength side, improving the separation between excitation light and weak fluorescence signals.

High contrast fluorescence observation with transmitted LED light

High-contrast fluorescence viewing

Strong excitation and background suppression help make fluorescent bands or stained regions easier to observe and capture, especially when used with the appropriate emission filter and camera settings.

LED transmitted light features and system design

Practical microscope-stage design

The die-cast aluminum body and heat-sink structure support stable operation. The included fixing stage plate, compact body and front dimmer make the system easy to use on many stereo microscope stages.

LED505 or LED470? The best wavelength depends on the excitation profile of the reagent. For gel dyes and fluorescent samples, confirm the recommended excitation wavelength and emission filter before selecting the model.

Recommended Filter Holder Set

For fluorescence observation with a stereo microscope, the transmitted excitation light should be combined with a suitable emission filter. The microscope filter holder keeps the emission filter in the optical path above the objective side, helping separate fluorescence from excitation light.
