Sky Quality Meter - L (SQM-L) from Unihedron: Measure the Quality of the Night Sky with Accuracy

Visit Sky Quality Meter - L (SQM-L) from Unihedron is a portable device specially designed to measure the brightness of the night sky with great precision. It's ideal for astronomers and astrophotographers thanks to its narrow measuring field and enhanced sensitivity.

Key features

  • Angular sensitivity : The SQM-L is equipped with a lens that reduces the measurement field to an angle of 20° (FWHM), with an HWHM of around 10°, enabling precise, localized measurements.
  • Measuring range : Measures brightness in magnitudes per square arcsecond (mag/arcsec²), with typical values ranging from 16 (very bright sky) to 23 (extremely dark sky).
  • Sensor : Uses a TAOS TSL237S sensor, sensitive only to visible light thanks to a HOYA CM-500 filter that blocks infrared.
  • Display : LCD display showing brightness and temperature (in °C or °F).
  • Measuring time : Fast measurement in approx. 8 seconds, even in dark environments.

Benefits and applications

  • Greater precision : Its narrow field of view makes it possible to assess sky quality in specific areas, such as the zenith or targeted regions.
  • Time tracking : Ideal for monitoring the evolution of light pollution on a given site, enabling long-term follow-up.
  • Ease of use : Lightweight and compact, simply point the device at the zenith and press a button for an accurate measurement.

Scope of delivery

  • Sky Quality Meter - L
  • 9V battery
  • Carrying pouch

In a nutshell

Visit SQM-L is a must-have tool for amateurs and professionals wishing to objectively analyze the quality of the night sky with exceptional precision. Its ease of use, portability and ability to provide local measurements make it the perfect tool for any light pollution study.
