Ultra-High Brightness LED Light Source

               Click to enlarge

The UHP-T-SR is a Ultra-High Brightness LEDs series featuring unique LED chips. The UHP-T-SR proprietary thermal management enables us to drive the LED die at high current density, making the UHP-T-SR series a top-brightness system. The UHP-T-SR collimated LED head features built-in adjustable aspheric collimator to provide collimated LED beam. Applications such as fluorescence microscopy, confocal microscopy, chemical reaction activation and numerous others can benefit from this design.
The shielded UHP-T-SR LED head contains the high current driver, while the LED controller box contains 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. These features make this product especially suited for electrophysiology rig applications. UHP-T-SR can be used with a full range of other optical OptiBlocks such as Fiber Coupler, Liquid Light Guide coupler, Beam Combiner, Filter Wheel, Beam Switcher and others.
Please see Optional Accessories section  below.

 Optional Accessories

   For full details on optional accessories please see:



Beam Combiner [2]

Multiple LED beams can be combined into one output beam. For example UV LED can be combined with White LED to create Mercury lamp like configuration. For more details please see: http://www.youtube.com/watch?v=iv7dlwLHaUE

Filter Wheel [7]

The UHP-Mic-LED can equipped with a 6 positions filter wheel at the beam output. This accessory is especially useful for UHP-Mic-LED-White light source. Please see https://www.prizmatix.com/Optics/filter-wheel.htm for more details

Fiber Coupler Adaptor [3]

All Prizmatix LED heads can be easily changed from collimated LED source to fiber coupled LED configuration by means of Fiber Coupler Adaptor (SMA, FC or ST connector). .
For more details please see video clip

Liquid Light Guide Adaptor [9]

The Microscope-LED can be easily changed from direct microscope coupling to Liquid Light Gide coupled LED configuration by means of LLGA Adaptor For more details please see video clip

Fiber Optics Collimator [13]

The output from optical fiber is divergent according to fiber NA. In order to reduce the divergence angle a collimator module can be used. Prizmatix collimator was especially designed to fit thick core high NA Polymer Optical Fibers. See more details at https://www.prizmatix.com/optics/collimator.htm

Fiber Bundles [4]

To combine outputs of multiple LEDs a Y-shaped fiber bundle with two or more input branches can be used. Prizmatix can help to configure and build custom fiber bundles for specific applications. See more details at https://www.prizmatix.com/dev/Custom-Fiber-Optic-Assemblies.htm
