Important LED Safety Information

Use caution when operating LUX LEDs. High-power light output from the LUX LEDs can be harmful to the eyes and skin. Never look directly at any LED light output, either from the LED module directly or from the output of a connected optical cable. For ultra-violet (UV) LEDs (415 nm and lower), extra precaution must also be taken to avoid direct light exposure to skin. Protective eyewear, such as these from ThorLabs, should be worn when operating LEDs.

LUX Photosensors

TDT LUX integrated photosensors have a wide bandwidth and gain for detecting fluorescent response signals in a large variety of fiber photometry applications. They also have a large voltage range to avoid sensor saturation. TDT LUX photosensor components require no external batteries or connectors when used with the RZ10X processor or iX6 / iConZ configuration.

Product Specs
Bandwidth DC – 700 Hz
Wavelength Range 320 – 1100 nm
Max Responsivity (A/W) 0.6 (at 960 nm)
Gain 1×1010
Photosensor Sensitivity 240 fW @ 375 nm
55 fW @ 900 nm

LUX Power Meter

The PMI Power Meter takes the guesswork out of your fiber photometry setup. Prior to recording, measure the power of your rig and optimize your signal. TDT’s Fiber Photometry Gizmo displays power output, light loss, and distortion.

Product Specs
Bandwidth DC – 3000 Hz
Wavelength Range 320 – 1100 nm
Gain 6.5×104
Sensitivity 36 nW @ 375 nm
8.2 nW @ 900 nm

LUX Cable Kit

The LUX Cable Kit has been optimized for fluorophore stimulation and detection for two and three LED configurations.

Includes:
  • Drive Cables (small diameter):

    • Connects the LEDs to optical filter (e.g. minicube)
    • Minimizes the potential for photobleaching of fluorophores
  • Response Cable (large diameter):

    • Connects the optical filter to the PS2
    • Maximizes the fluorophore signal
  • Subject Cable (low autofluorescent):

    • Connects the optical filter to the Power Meter
    • Measures power output
