Two Color Detectors |
 |
Westlake Village, California, August 3, 2009. The PSS silicon “sandwich” detector consists of two vertically stacked 3.6mm diameter active area silicon PIN photodiodes. The top silicon detector acts as a long-pass filter, only allowing wavelengths greater than 950nm to pass through it to the bottom detector. The unique signature created by the dual current outputs can be used to identify source wavelength or Color temperature by comparing ratios with the standard black body radiation curves.

Pacific
Silicon Sensor Inc. just introduced
a new Wavelength Sensor and Circuit. The WS-7.56-PCBA2
(PDF), is a unique wavelength
sensor based on Silicon Photodiode Technology. The sensor
is constructed monolithically by superimposing two photodiodes

Wavelength
Sensor |
 |
Westlake
Village, California, June 1,2000 - WS-7.56 is
a wavelength sensor operating in the range of 450 to 900 nm.
This unique sensor can determine the actual wavelength of monochromatic
light (such as lasers or LED's) and determine the spectral
peak of light containing many wavelengths. The measurement
is accomplished by comparing the light entering two silicon
photodiode junctions superimposed on each other. The top layer
junction absorbs the shorter wavelengths (such as blue light)
and passes the longer wavelengths (such as red light). the
quotient of the two outputs is directly proportional to the
incident wavelength. This is independent of light intensity
until saturation occurs. The sensor has an active area of 7.56mm2 and
is housed in a hermetically sealed TO-5 case. Applications
include laser testing, LED sorting, analytical instruments
and color matching. |
