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

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

Main Features

• USB connectivity : Connects the device to a computer for direct data transmission 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 : Uses a TAOS TSL237S sensor combined with a HOYA CM-500 infrared-blocking filter, guaranteeing 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 quality with CCD or CMOS sensor performance during imaging sessions.
• Transportable and practical: Lightweight and compact, it can be used at different locations to objectively compare sky quality between several sites.
