LS182 (Model): Product Features: 47mm notch, capable of measuring seven parameters: 365nm ultraviolet, full-band visible light, 940nm infrared, 1400nm infrared full infrared, SHGC, TSER.
LS182 is currently the most fully functional desktop demonstration optical transmittance measuring instrument. It has three switchable gears and can measure seven values, which are SHGC (Solar Heat Gain Coefficient), TSER (Total Solar Energy Rejection), visible light transmittance, ultraviolet rejection rate, infrared 940nm, 1400nm, and full infrared rejection rate. It can comprehensively evaluate the optical performance of solar films, glass and other materials.
Core Advantages:

Switchable between three gears: 940nm/1400nm/full infrared rejection rate.
Capable of measuring 7 parameters: ultraviolet rejection rate, 940nm, 1400nm and full infrared rejection rate, visible light transmittance, TSER, and SHGC.
Adopts parallel optical path design, which can accurately measure large-thickness materials.
The instrument has a real-time dynamic self-calibration function and can self-calibrate when turned on.
Can be powered by a 5V power supply or connected to a mobile power supply via a USB interface.
