Abstract

The Jarrell-Ash Company Recording Microphotometer is a new instrument which incorporates the fundamental photometric advantages of the Jarrell-Ash Non-recording Microphotometer. The instrument will accommodate two 4×10 inh plates or 20 inches of 35mm film in both the sample and master-comparison projected fields. Both fields are in view at all times. A variable slit is incorporated over the detector. Scanning mechanism, detector-screen assembly, visual deflection meter, and recorder are different in the recording instrument.
