Improved optical chamber for small measuring cells with temperature control

Mostrar todas las versiones(2)

An improved optical chamber is described containing a Chatelain prism with controlled heating and temperature control. It consists of placing the prism between two copper plates heated through a miniaturized device that creates a hot air current inside a small acrylic chamber. The heater is a power...
