The UHP-T-MP series Ultra High Power LEDs feature a powerful rectangular collimated LED beam. These LEDs are useful for direct illumination of biological Well Plates (such as for example 96 well microplate). These Collimated LEDs are excellent for such power demanding applications as Optogenetics with Channelrhodopsin (ChR2), ArchT, Halorhodopsin (NpHR) and other Opsins, Photoactivation, Uncaging, Photobleaching and Photochemistry.

The UHP-T-MP optics contains aspheric lens to create collimated LED beam with almost flat field illumination of standard 96 well microplate from working distance of about 40cm (see example of beam profile).

The unique LED head design of UHP-T-MP LED features shielded LED head metal enclosure which contains high current driver. The UHPTLCC LED controller performs control functions. This arrangement eliminates much of RFI / EMI interference common in high current light sources. The controller features Optically Isolated TTL and Analog Inputs. All these features make this product especially suited for electrophysiology rig applications.

UHP-T-MP LED can be used with a full range of other optical OptiBlocks such as, Liquid Light Guide coupler, Beam Combiner, Filter Wheel,Beam Switcher and others.

Please see full list of optional accessories below.


Key Features:

  • Single chip Ultra High Power LED 3:4 aspect ratio.
  • Close to Flat Field Collimated beam.
  • Optically isolated TTL input for external triggering (no shutter needed) or strobe operation.
