RGB LED Light Source enables independent control of red (619 nm), green (515 nm), and blue (465 nm) LEDs to create any desired color, including white light, for visual observation. Color images can be produced from monochrome cameras, giving full non-interpolated color at every pixel. Light source head mounts instead of condenser on upright microscopes and does not create any vibration or noise. Light source controller connects to computer serial or USB port.
