Transmittance Measurement of IR-Cut Glass Using a UV-2600 UV-VIS Spectrophotometer with ISR-2600Plus Integrating Sphere

Introduction

With the evolution of mankind and the accompanying development of technology, energy consumption has steadily increased. However, because energy sources such as oil and natural gas are limited, a variety of innovations have been introduced with the aim of reducing energy consumption. One of these is IR-cut glass, which effectively limits the rise of indoor temperature by filtering out near-infrared rays. On the other hand, while cutting near-infrared radiation is an effective means of conserving energy, it is also important to ensure that visible light is effectively transmitted to the interior to permit outside light to help illuminate the interior of a room. Here we introduce use of the auto point pick feature newly added to the s tandard sof tware to ver i f y the effectiveness of IR-cut processing in window glass.
