Lumidox® II LED Arrays - Analytical Sales and Services, Inc.

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

Solid Base:

External cooling source is required (see Thermal Transfer Deck)
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

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.

LED Output STAGES
By default, all Lumidox II devices are factory calibrated with 5 discrete linearly stepped output STAGES. STAGE 1 output is the least radiometric power while STAGE 5 output is the most. STAGES are calibrated to the nearest whole number of radiant flux, and displayed in milliwatts (mW).

Custom Tuned STAGES
Analytical offers custom tuned stages to meet specific and unique requirements. These can range from maximum light output to low output to tight resolution. NOTE: STAGE settings are stored on each individual Lumidox® II peripheral device (LED Array or Lumlamp), and are not tunable via the controller. Custom STAGE settings can only be calibrated by Analytical Sales and Services prior to shipment. Please contact Analytical before ordering.
