Analytical’s patented LED arrays provide wavelength and power specific illumination to samples for photoredox catalysis applications.
Up to 15 different color wavelengths are available*
5 output STAGES (customizeable) with calibration data stored on board**
Available in two Surface Mat styles
Three options for Base configurations
Lumidox II LED Arrays are available in up to 15 wavelengths*:
365nm UV, 375nm UV, 385nm UV, 395nm UV, 405nm UV, 420nm-Violet, 445nm-Indigo, 470nm-Blue,
505nm-Cyan, 527nm-Green, 590nm-Amber, 630nm-Red, 660nm-Deep Red, 730nm-IR Infrared and White
* Most LED arrays (excluding Discovery) are wavelength-specific - only one wavelength per device
** Calibration data is stored onboard (not on the controller), allowing the use of different illuminators with one controller. Controller can only operate 1 device at a time. STAGE settings are NOT user-adjustable and must be configured prior to shipping
Surface Mat Styles
Array top surfaces come in two styles, Lens Mat and Diffuse Mat.
Lens Mat Surface
Ultra-clear, molded to fit into the holes of a Para-dox® Reaction Block
Captures nearly all light emitted by the array’s LEDs and directs it into the vials in the reaction block
Chemically inert silicone
Diffuse Mat Surface
Flat surface, making for easy pairing with SLAS footprint apparatus
Can be used for niche applications such as illuminating cell culture flasks, reservoir plates, large scale containers, etc.
Chemically inert silicone
About Array Cooling and Base Options
Lumidox® II LED Arrays can generate a considerable amount of heat at any output stage and therefore need to be cooled. Both Lens Mat and Diffuse Mat style arrays are available with an Active Cooling base, Solid base or Flow-Through base. Each has it’s own specific way of cooling the LEDs in the array and can affect different application situations.
Active Cooling Base:
Self-cooling, no external cooling source required
Fully conforms to SLAS/ANSI standard dimensions
Ideal for lower output applications like cell culture and PCR work (may require special adapter)
Not compatible with tumble stirrers or devices that generate powerful magnetic fields
A Thermal Transfer Deck (TTD) is recommended and can be attached to the base when used in conjunction with a recirculating chiller. The TTD can be removed if using a different cooling source, such as a cooling bay
Fully conforms to SLAS/ANSI standards and can be used with cooling baths, plates, or other cooling chamber (if NOT being used with our Thermal Transfer Deck and recirculating liquid chiller)
Ideal for applications requiring high output - up to nearly 3x more radiometric power output than Active Base arrays
NEW!Flow-Through Base:
Provides the most optimal cooling efficiency for LED arrays
Direct connection to recirculating liquid chiller (required). Cooled liquid flows through the array base itself (no need for Thermal Transfer Deck)
Ideal for applications requiring high output - up to nearly 3x more radiometric power output than Active Base arrays
Light Weight – improved usability with orbital shakers due to lower overall mass
Shorter overall height than active base array – offers improved compatibility with tumble stirrers (less distance between stirrer and sample)
Note: Flow-through base LED arrays can only be used with an independent, dedicated recirculating chiller circuit. They cannot be daisy chained with any other hardware.
Note: All LED arrays can operate in an incubator at 37ºC, 95% humidity
For added protection, each device has a built-in thermal cutoff switch that, in case of overheating, will automatically shut down the unit. The trip temperature for Solid Base and Flow-thru Base Arrays is 95°C, and will
reset when cooled to 65°C. Active Cooling Base Arrays will shut down if their temperature exceeds 75°C. They will reset once they have cooled to 45°C.
Note: Active Cooling Base arrays are not compatible with strong magnetic fields such as those found in most tumble stirrers due to interference with the cooling fans.
Lumidox® II STAGES
By default, all Lumidox II devices are factory calibrated with 5 discrete linearly stepped output STAGES... Expand
Lumidox® II STAGE Selection
By default, all Lumidox II devices are factory calibrated with 5 discrete linearly stepped output STAGES (Example 1, below). STAGE 1 output is the least radiometric power while STAGE 5 output is the most. For LED arrays with Active Cooling Stage bases, STAGE 5 thermal dissipation requirements are configured to an appropriate level for each device's built-in thermal satisfaction abilities. STAGE 5 defaults for Passive (solid) Base Arrays are tuned to be thermally satisfied with an average powered chiller in thermal contact with the array base. STAGES are calibrated to nearest whole number of radiant flux, and displayed in milliwatts (mW).
Analytical Sales & Services offers custom tuned stages to meet specific and unique requirements. A user, for example, may have a more sophisticated cooling mechanism and require an array tuned for maximum light output. In this scenario, Analytical would tune the upper STAGES to higher levels than typically thermally controllable by standard users (Example 2). In another example, a user may have a need for a tighter resolution of STAGES (Example 3).
For custom STAGE settings, please contact Analytical Sales & Services before ordering. Note: STAGES may only be calibrated at the time of shipment.
