Of late, the microspectrophotometry has been regarded as of necessity and is being eagerly taken up in the fields of biological, medical and physical studies as we see for example in the determination of spectral transmission of various objects such as blood corpuscles, nuclei of cells, cancer cells and many kinds of microcrystals.
A single-beam microspectrophotometric apparatus, into which a PbS photoconductive infrared detector is incorporated, has been constructed enabling the intended work in near infrared region to be carried out. Its optical system consists of a double monochromator, objectives, eyepieces and other usual parts, and its photometric system, a PbS photoconductive detector, a main ampli-fier and other customary appliances. With ×30 and ×10 objectives, over 200 signal-to-noise ratios within the region of 0.8_??_1.5μ in wavelength were successfully obtained.
