Cylindrical irradiance is less directional than irradiance; it includes UV radiation over essentially 47[pi] steradians
; that is, all of the possible directions from which UV rays might originate are included.
Legacy Whisper ($12,900, price includes a dedicated Steradian
processor) Reviewed by WCH in Issue 73.
Semiconductor is a fabless semiconductor company based out of Bangalore, India.
The units of radiance are W/[m.sup.2]sr where sr (steradians
) are solid angle units (5).
Later, I received a production version of the Steradian
. The box was still black, but it was now much more attractive.
The number of photoelectrons per steradian
per unit light flux, [dN.sub.v]/d[ohm] is proportional to the differential cross section and hence we can recast the above equation into one that refers to the measurable parameters of the experiment:
Processor: The Whispers come with a dedicated version of the Steradian
electronic processor, somewhat similar to the Steradian
unit that KWN described in his review of the Legacy Focus speakers, but with an algorithm especially designed for the bass characteristics of the Whispers.
Thus, it is normally necessary to consider threats from the complete sphere surrounding the aircraft, which is called "4 p steradian
coverage" as shown in Figure 2.
- Capacity of the minimum quantum CCD camera equal to or greater than 70% for wavelengths between 450 nm and 800 nm (extended beyond 700 nm, and then in the infrared), with a detection limit of less than or equal to 70 photons / second / cm / steradian
and a limit of sensitivity of the camera to detect between 10 and bioluminescent cells (4T1 cells transformed with gene luc2 Promega) in a rat subcutaneous athymic Nu / Nu.
The specified frequency was chosen to be at the peak of the V([lambda]) distribution (555 nm) and the factor 1/683 watts per steradian
was chosen based upon the best estimate at that time of the freezing point of platinum.
If you absolutely insist on spending six grand, the Legacy Focus speakers with Steradian
processor offer an overall combination of bass performance, dynamic capability, mid an ability to match to various rooms that are unmatched at this price point.
I have become quite spoiled by the Legacy Focus speakers and their associated Steradian
environmental processor, which form an admittedly quite expensive ($5,000+) loudspeaker system.
