Print on Demand. This book presents modifications to a state-of-the-art reference spectrophotometer that enhance its capabilities and accuracy to new heights, delving into the ultraviolet region of the spectrum and implementing advanced automation. The modifications discussed, including the integration of novel averaging spheres and automation via a specialized data acquisition platform, allow for unprecedented precision in transmittance measurements, even for challenging samples such as scattering filters. The book provides a comprehensive exploration of the technical aspects of these advancements and their implications for accurate optical measurements. Extending its reach into the ultraviolet spectrum empowers users to analyze samples across a wider range of applications. The significance of this work lies in its contribution to the field of high-precision spectrophotometry, enabling scientists, researchers, and industrial professionals to unlock new possibilities in their respective disciplines. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.…

- Physics
A pneumatically controlled sliding sample holder was constructed. The temperature of samples mounted in this holder is controlled by water circulated in the holder and in a jacket surrounding the filter to also maintain the temperature of the air surrounding the filter. The holder - jacket combination is three point spring loaded.
The circulating water temperature is provided by a bath which was modified. The heaters and refrigerator (approximately 670 watts each) of the bath were isolated and ad justed so that in combination they yield a nearly constant temperature. Then, a 300 watt heater was installed to tune the temperature to the desired level. A special proportional controller was obtained which shuts off the heater or refrigerator (depending on whether one desires a lower or higher temperature) for large temperature changes (several degrees C) until the temperature reaches the range where the 300 watt heater is cycled to maintain a constant temperature as detected by a thermistor placed in the bath.
