BLINKFR: A SUPERIOR TECHNOLOGY

blink-side

BLINKFR sensors are based on a proprietary technology which enables natural response times of 90 msec (typ) while still keeping broadband spectral range, power density capability and direct high power operation up to 60W of comparable thermopile detectors.

The response time is a key parameter for laser detectors where a faster response is required because several phenomena like pointing stability, fast drifts, instabilities can only be monitored if the detector responds very quickly. However, when the detector is fast it cannot withstand high powers (as is the case of all photodetectors) or, vice-versa, when the detector can withstand the power, it is slow (as it happens with thermopile sensors or Peltier devices).
Photodetectors can respond to pulses < 1nsec. They can only withstand few milliwatts of direct laser power and their advantage of a fast response is, in most of applications, spoiled by standard readout electronics which curb the response time to 0.1-0.2 sec.
grafico
Thermopile detectors are inherently slow: their natural response times range from > 1sec to several tens of seconds, depending on the maximum power rating. Those natural response times can be reduced by electronics circuits and speed-up algorithms, but cannotbe lower than 800msec-1 sec, and only in the case of very low power heads.
BLINKFR sensors, differently from thermopile sensors, offer an unreached natural (without any acceleration by additional electronics) response time down to 90 msec (typ.). This is a game changing feature for laser power measurement because it paves the way to a number of applications that were not possible before.
