Sky Quality Meter (SQM) - LR

Unihedron's Sky Quality Meter – LR (SQM-LR): Advanced Measurement of Night Sky Quality

The Sky Quality Meter – LR (SQM-LR) from Unihedron is an advanced version of the well-known night sky quality meter. This model is designed to offer enhanced functionality, including the ability to be remotely controlled, making it ideal for fixed observatories and automated monitoring projects.

Main Features

• Remote connectivity : The SQM-LR model allows remote control, making it perfect for automated systems or fixed observatories.
• Measuring range : It measures the sky's brightness in magnitudes per square arcsecond (mag/arcsec²), providing high accuracy even in the darkest locations.
• Angular sensitivity : With a built-in lens that limits the measurement field to an angle of 20° (FWHM), it enables precise measurements on specific areas of the sky.
• Sensor and filter : Equipped with the TAOS TSL237S sensor and a HOYA CM-500 filter, which blocks infrared light, ensuring measurements are taken only in the visible spectrum.

Benefits and applications

• Automated monitoring : Thanks to its remote connectivity, the SQM-LR is ideal for observatories or facilities requiring continuous, autonomous sky monitoring.
• Scientific research : Perfect for research projects requiring regular and accurate light pollution data collection.
• Site comparison : Allows objective comparisons of sky quality between different observation sites.
