TQ821 0 Optical Power Meter 1., INTRODUCTION 1.1 Standard Features The T08210 is a convenient, lightweight, and portable optical power meter. It can measure optical power for four different wave- length ranges in the range from 400 to 1650 nm, depending on which o f optical sensors 1082014, T082015, T082017, and 082018A are used.
Available Optical Sensors 1.2 Av a i l a b l e Optical Sensors (I) T 0 8 2 0 1 4 Short Wavelength Beam Sensor Figure 1-1 T 0 8 2 0 1 4 Short Wavelength Beam Sensor With o n e o f the following connector adapters, t h e T082014 can be used for optical fiber beam measure- ment.

T0821 0 Optical Power Meter 2.6 ZERO Key The t i key is used to memorize the sensor offset value and to cancel the offset. Cover the sensor input. For TO82014, TO82015, and 082018A put on the cap on the sensor input. F o r TO82017, closing the sliding cover is not enough for light shielding.
Wavelength K e y 2.7 Wavelength Ot) Key When the wavelength of the light to be measured is input, the 108210 can compensate for the nonlinearity errors of the connected sensor. An example of input- ting a wavelength of 780 nm is given below. Small LCD Large L C D Operation...

THEORY OF OPERATION 3. THEORY OF OPERATION Figure 3-1 Block Diagram of T08210 When light strikes the photodiode, the photodiode passes electric current proportional to the intensity of the light. The current is converted into voltage and input to the A/D converter. The output signal from the A/D converter is sent to the CPU, sensor sensitivity compensation is performed for the optical wavelength, then the signal is output to the LCD driver as optical...
