Sky Quality Meter (SQM) - LU - DL

Sky Quality Meter – LU-DL (SQM-LU-DL) by Unihedron: Measure Night Sky Quality with USB Connectivity

The Sky Quality Meter – LU-DL (SQM-LU-DL) from Unihedron is an advanced photometer, specifically designed to measure the brightness of the night sky. With its USB connectivity and data-logging capabilities, it is the ideal tool for astronomers, astrophotographers, and researchers studying light pollution.

Main Features

• USB connectivity : Allows you to connect the device to a computer for direct data transfer and continuous recording.
• Stand-alone recording : Capable of collecting and storing data without constant intervention, ideal for long-term monitoring.
• Measuring range : Measures sky brightness in magnitudes per square arcsecond (mag/arcsec²), with typical values ranging from 16 (very bright sky) to 23 (extremely dark sky).
• Angular sensitivity : Featuring an integrated lens, it offers a precise 20° measuring field (FWHM), perfect for localized measurements.
• Sensor : It uses a TAOS TSL237S sensor combined with a HOYA CM-500 infrared-blocking filter, ensuring accurate measurements in the visible spectrum.

Benefits and applications

• Continuous monitoring : Ideal for documenting the evolution of light pollution on a given site, without the need for frequent intervention.
• Scientific research : Perfect for projects requiring regular, accurate data on the quality of the night sky.
• Astrophotography : Helps correlate sky conditions with the performance of CCD or CMOS sensors during imaging sessions.
• Transportable and practical: Lightweight and compact, it can be used at different locations to objectively compare sky quality between several sites.
