4 ports - LED & Doric Detector Heads - Lock-in or Sequential Detection

ilFMC4-G2_IE(400-410)_E(460-490)_F(500-550)_S

This cube permits excitation of the GCaMP isosbestic point with 400-410 nm light and fluorophores with 460-490 nm light. The single detector measures both signals within the fluorescence detection window from 500-550 nm.

More details

In order to optimize signal detection and simplify usage, it is desirable to minimize the number of fiber optic connections to a Fluorescence Mini Cube. By taking advantages of the new Doric Fluorescence Detector, and our Built-in LED Optical Heads, it is possible to have an Integrated Fluorescence Mini Cube.

  • The Built-in Fluorescence Detector Head allows for an increase in signal transmission of 30 % due to the proximity of the detector active surface and signal source, as well as the reduced number of optical connections. A Fluorescence Detector Amplifier is provided for each detector head.

  • The Built-in LED Optical Head removes the need for light source patch cords. The Intensity Adjustment Ring allows additional fine control of light intensity, ideal for low-power fiber photometry experiments. All Fluorescence Mini Cube E and IE ports come with a Built-in LED Optical Head.

  • Any built-in device can be replaced by an FC Receptacle if requested.


This cube permits excitation of the GCaMP isosbestic point with 400-410 nm light and fluorophores with 460-490 nm light. The single detector measures both signals within the fluorescence detection window from 500-550 nm. The separation of GCaMP isosbestic and functional excitations is possible if both excitations are modulated.

On the image IE and E are ports for excitations, F is for fluorescence detection and S is the for fixed sample port. The numbers in the brackets of the ordering code denote the corresponding wavelength bands.

    Doric Connectorized LEDs couple high brightness LEDs into an FC receptacle compatible with an FC connectorized fiber-optic patch cord. Each Connectorized LED is actively aligned for optimum output power and its optical design provides the maximum fiber-coupling efficiency into multimode optical fibers.
